-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-		     
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990

-That's all there is to it!

+
+Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence
 for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features
 is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL),
 inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility
 without requiring unnecessary code duplication.

+# Upgrade to 2.3
+
+## EntityGenerator add*() method generation
+
+When generating an add*() method for a collection the EntityGenerator will now not
+use the Type-Hint to get the singular for the collection name, but use the field-name
+and strip a trailing "s" character if there is one.
+
+## Merge copies non persisted properties too
+
+When merging an entity in UoW not only mapped properties are copied, but also others.
+
+## Query, QueryBuilder and NativeQuery parameters *BC break*
+
+From now on, parameters in queries is an ArrayCollection instead of a simple array.
+This affects heavily the usage of setParameters(), because it will not append anymore
+parameters to query, but will actually override the already defined ones.
+Whenever you are retrieving a parameter (ie. $query->getParameter(1)), you will
+receive an instance of Query\Parameter, which contains the methods "getName",
+"getValue" and "getType". Parameters are also only converted to when necessary, and
+not when they are set.
+
+Also, related functions were affected:
+
+* execute($parameters, $hydrationMode) the argument $parameters can be either an key=>value array or an ArrayCollection instance
+* iterate($parameters, $hydrationMode) the argument $parameters can be either an key=>value array or an ArrayCollection instance
+* setParameters($parameters) the argument $parameters can be either an key=>value array or an ArrayCollection instance
+* getParameters() now returns ArrayCollection instead of array
+* getParameter($key) now returns Parameter instance instead of parameter value
+
+## Query TreeWalker method renamed
+
+Internal changes were made to DQL and SQL generation. If you have implemented your own TreeWalker,
+you probably need to update it. The method walkJoinVariableDeclaration is now named walkJoin.
+
+## Metadata Drivers
+
+Metadata drivers have been rewritten to reuse code from Doctrine\Common. Anyone who is using the
+`Doctrine\ORM\Mapping\Driver\Driver` interface should instead refer to
+`Doctrine\Common\Persistence\Mapping\Driver\MappingDriver`. Same applies to
+`Doctrine\ORM\Mapping\Driver\AbstractFileDriver`: you should now refer to
+`Doctrine\Common\Persistence\Mapping\Driver\FileDriver`.
+
+Also, following mapping drivers have been deprecated, please use their replacements in Doctrine\Common as listed:
+
+ *  `Doctrine\ORM\Mapping\Driver\DriverChain`       => `Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain`
+ *  `Doctrine\ORM\Mapping\Driver\PHPDriver`         => `Doctrine\Common\Persistence\Mapping\Driver\PHPDriver`
+ *  `Doctrine\ORM\Mapping\Driver\StaticPHPDriver`   => `Doctrine\Common\Persistence\Mapping\Driver\StaticPHPDriver`
+
+# Upgrade to 2.2
+
+## ResultCache implementation rewritten
+
+The result cache is completely rewritten and now works on the database result level, not inside the ORM AbstractQuery
+anymore. This means that for result cached queries the hydration will now always be performed again, regardless of
+the hydration mode. Affected areas are:
+
+1. Fixes the problem that entities coming from the result cache were not registered in the UnitOfWork
+   leading to problems during EntityManager#flush. Calls to EntityManager#merge are not necessary anymore.
+2. Affects the array hydrator which now includes the overhead of hydration compared to caching the final result.
+
+The API is backwards compatible however most of the getter methods on the `AbstractQuery` object are now
+deprecated in favor of calling AbstractQuery#getQueryCacheProfile(). This method returns a `Doctrine\DBAL\Cache\QueryCacheProfile`
+instance with access to result cache driver, lifetime and cache key.
+
+
+## EntityManager#getPartialReference() creates read-only entity
+
+Entities returned from EntityManager#getPartialReference() are now marked as read-only if they
+haven't been in the identity map before. This means objects of this kind never lead to changes
+in the UnitOfWork.
+
+
+## Fields omitted in a partial DQL query or a native query are never updated
+
+Fields of an entity that are not returned from a partial DQL Query or native SQL query
+will never be updated through an UPDATE statement.
+
+
+## Removed support for onUpdate in @JoinColumn
+
+The onUpdate foreign key handling makes absolutely no sense in an ORM. Additionally Oracle doesn't even support it. Support for it is removed.
+
+
+## Changes in Annotation Handling
+
+There have been some changes to the annotation handling in Common 2.2 again, that affect how people with old configurations
+from 2.0 have to configure the annotation driver if they don't use `Configuration::newDefaultAnnotationDriver()`:
+
+    // Register the ORM Annotations in the AnnotationRegistry
+    AnnotationRegistry::registerFile('path/to/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php');
+
+    $reader = new \Doctrine\Common\Annotations\SimpleAnnotationReader();
+    $reader->addNamespace('Doctrine\ORM\Mapping');
+    $reader = new \Doctrine\Common\Annotations\CachedReader($reader, new ArrayCache());
+
+    $driver = new AnnotationDriver($reader, (array)$paths);
+
+    $config->setMetadataDriverImpl($driver);
+
+
+## Scalar mappings can now be ommitted from DQL result
+
+You are now allowed to mark scalar SELECT expressions as HIDDEN an they are not hydrated anymore.
+Example:
+
+SELECT u, SUM(a.id) AS HIDDEN numArticles FROM User u LEFT JOIN u.Articles a ORDER BY numArticles DESC HAVING numArticles > 10
+
+Your result will be a collection of Users, and not an array with key 0 as User object instance and "numArticles" as the number of articles per user
+
+
+## Map entities as scalars in DQL result
+
+When hydrating to array or even a mixed result in object hydrator, previously you had the 0 index holding you entity instance.
+You are now allowed to alias this, providing more flexibility for you code.
+Example:
+
+SELECT u AS user FROM User u
+
+Will now return a collection of arrays with index "user" pointing to the User object instance.
+
+
+## Performance optimizations
+
+Thousands of lines were completely reviewed and optimized for best performance.
+Removed redundancy and improved code readability made now internal Doctrine code easier to understand.
+Also, Doctrine 2.2 now is around 10-15% faster than 2.1.
+
+## EntityManager#find(null)
+
+Previously EntityManager#find(null) returned null. It now throws an exception.
+
+# Upgrade to 2.1
+
+## Interface for EntityRepository
+
+The EntityRepository now has an interface Doctrine\Common\Persistence\ObjectRepository. This means that your classes that override EntityRepository and extend find(), findOneBy() or findBy() must be adjusted to follow this interface.
+
+## AnnotationReader changes
+
+The annotation reader was heavily refactored between 2.0 and 2.1-RC1. In theory the operation of the new reader should be backwards compatible, but it has to be setup differently to work that way:
+
+    // new call to the AnnotationRegistry
+    \Doctrine\Common\Annotations\AnnotationRegistry::registerFile('/doctrine-src/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php');
+
+    $reader = new \Doctrine\Common\Annotations\AnnotationReader();
+    $reader->setDefaultAnnotationNamespace('Doctrine\ORM\Mapping\\');
+    // new code necessary starting here
+    $reader->setIgnoreNotImportedAnnotations(true);
+    $reader->setEnableParsePhpImports(false);
+    $reader = new \Doctrine\Common\Annotations\CachedReader(
+        new \Doctrine\Common\Annotations\IndexedReader($reader), new ArrayCache()
+    );
+
+This is already done inside the ``$config->newDefaultAnnotationDriver``, so everything should automatically work if you are using this method. You can verify if everything still works by executing a console command such as schema-validate that loads all metadata into memory.
+
+# Update from 2.0-BETA3 to 2.0-BETA4
+
+## XML Driver <change-tracking-policy /> element demoted to attribute
+
+We changed how the XML Driver allows to define the change-tracking-policy. The working case is now:
+
+    <entity change-tracking-policy="DEFERRED_IMPLICT" />
+
+# Update from 2.0-BETA2 to 2.0-BETA3
+
+## Serialization of Uninitialized Proxies
+
+As of Beta3 you can now serialize uninitialized proxies, an exception will only be thrown when
+trying to access methods on the unserialized proxy as long as it has not been re-attached to the
+EntityManager using `EntityManager#merge()`. See this example:
+
+    $proxy = $em->getReference('User', 1);
+
+    $serializedProxy = serialize($proxy);
+    $detachedProxy = unserialized($serializedProxy);
+
+    echo $em->contains($detachedProxy); // FALSE
+
+    try {
+        $detachedProxy->getId(); // uninitialized detached proxy
+    } catch(Exception $e) {
+
+    }
+    $attachedProxy = $em->merge($detachedProxy);
+    echo $attackedProxy->getId(); // works!
+
+## Changed SQL implementation of Postgres and Oracle DateTime types
+
+The DBAL Type "datetime" included the Timezone Offset in both Postgres and Oracle. As of this version they are now
+generated without Timezone (TIMESTAMP WITHOUT TIME ZONE instead of TIMESTAMP WITH TIME ZONE).
+See [this comment to Ticket DBAL-22](http://www.doctrine-project.org/jira/browse/DBAL-22?focusedCommentId=13396&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_13396)
+for more details as well as migration issues for PostgreSQL and Oracle.
+
+Both Postgres and Oracle will throw Exceptions during hydration of Objects with "DateTime" fields unless migration steps are taken!
+
+## Removed multi-dot/deep-path expressions in DQL
+
+The support for implicit joins in DQL through the multi-dot/Deep Path Expressions
+was dropped. For example:
+
+    SELECT u FROM User u WHERE u.group.name = ?1
+
+See the "u.group.id" here is using multi dots (deep expression) to walk
+through the graph of objects and properties. Internally the DQL parser
+would rewrite these queries to:
+
+    SELECT u FROM User u JOIN u.group g WHERE g.name = ?1
+
+This explicit notation will be the only supported notation as of now. The internal
+handling of multi-dots in the DQL Parser was very complex, error prone in edge cases
+and required special treatment for several features we added. Additionally
+it had edge cases that could not be solved without making the DQL Parser
+even much more complex. For this reason we will drop the support for the
+deep path expressions to increase maintainability and overall performance
+of the DQL parsing process. This will benefit any DQL query being parsed,
+even those not using deep path expressions.
+
+Note that the generated SQL of both notations is exactly the same! You
+don't loose anything through this.
+
+## Default Allocation Size for Sequences
+
+The default allocation size for sequences has been changed from 10 to 1. This step was made
+to not cause confusion with users and also because it is partly some kind of premature optimization.
+
+# Update from 2.0-BETA1 to 2.0-BETA2
+
+There are no backwards incompatible changes in this release.
+
+# Upgrade from 2.0-ALPHA4 to 2.0-BETA1
+
+## EntityRepository deprecates access to protected variables
+
+Instead of accessing protected variables for the EntityManager in
+a custom EntityRepository it is now required to use the getter methods
+for all the three instance variables:
+
+* `$this->_em` now accessible through `$this->getEntityManager()`
+* `$this->_class` now accessible through `$this->getClassMetadata()`
+* `$this->_entityName` now accessible through `$this->getEntityName()`
+
+Important: For Beta 2 the protected visibility of these three properties will be
+changed to private!
+
+## Console migrated to Symfony Console
+
+The Doctrine CLI has been replaced by Symfony Console Configuration
+
+Instead of having to specify:
+
+    [php]
+    $cliConfig = new CliConfiguration();
+    $cliConfig->setAttribute('em', $entityManager);
+
+You now have to configure the script like:
+
+    [php]
+    $helperSet = new \Symfony\Components\Console\Helper\HelperSet(array(
+        'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($em->getConnection()),
+        'em' => new \Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper($em)
+    ));
+
+## Console: No need for Mapping Paths anymore
+
+In previous versions you had to specify the --from and --from-path options
+to show where your mapping paths are from the console. However this information
+is already known from the Mapping Driver configuration, so the requirement
+for this options were dropped.
+
+Instead for each console command all the entities are loaded and to
+restrict the operation to one or more sub-groups you can use the --filter flag.
+
+## AnnotationDriver is not a default mapping driver anymore
+
+In conjunction with the recent changes to Console we realized that the
+annotations driver being a default metadata driver lead to lots of glue
+code in the console components to detect where entities lie and how to load
+them for batch updates like SchemaTool and other commands. However the
+annotations driver being a default driver does not really help that much
+anyways.
+
+Therefore we decided to break backwards compability in this issue and drop
+the support for Annotations as Default Driver and require our users to
+specify the driver explicitly (which allows us to ask for the path to all
+entities).
+
+If you are using the annotations metadata driver as default driver, you
+have to add the following lines to your bootstrap code:
+
+    $driverImpl = $config->newDefaultAnnotationDriver(array(__DIR__."/Entities"));
+    $config->setMetadataDriverImpl($driverImpl);
+
+You have to specify the path to your entities as either string of a single
+path or array of multiple paths
+to your entities. This information will be used by all console commands to
+access all entities.
+
+Xml and Yaml Drivers work as before!
+
+
+## New inversedBy attribute
+
+It is now *mandatory* that the owning side of a bidirectional association specifies the
+'inversedBy' attribute that points to the name of the field on the inverse side that completes
+the association. Example:
+
+    [php]
+    // BEFORE (ALPHA4 AND EARLIER)
+    class User
+    {
+        //...
+        /** @OneToOne(targetEntity="Address", mappedBy="user") */
+        private $address;
+        //...
+    }
+    class Address
+    {
+        //...
+        /** @OneToOne(targetEntity="User") */
+        private $user;
+        //...
+    }
+
+    // SINCE BETA1
+    // User class DOES NOT CHANGE
+    class Address
+    {
+        //...
+        /** @OneToOne(targetEntity="User", inversedBy="address") */
+        private $user;
+        //...
+    }
+
+Thus, the inversedBy attribute is the counterpart to the mappedBy attribute. This change
+was necessary to enable some simplifications and further performance improvements. We
+apologize for the inconvenience.
+
+## Default Property for Field Mappings
+
+The "default" option for database column defaults has been removed. If desired, database column defaults can
+be implemented by using the columnDefinition attribute of the @Column annotation (or the approriate XML and YAML equivalents).
+Prefer PHP default values, if possible.
+
+## Selecting Partial Objects
+
+Querying for partial objects now has a new syntax. The old syntax to query for partial objects
+now has a different meaning. This is best illustrated by an example. If you previously
+had a DQL query like this:
+
+    [sql]
+    SELECT u.id, u.name FROM User u
+
+Since BETA1, simple state field path expressions in the select clause are used to select
+object fields as plain scalar values (something that was not possible before).
+To achieve the same result as previously (that is, a partial object with only id and name populated)
+you need to use the following, explicit syntax:
+
+    [sql]
+    SELECT PARTIAL u.{id,name} FROM User u
+
+## XML Mapping Driver
+
+The 'inheritance-type' attribute changed to take last bit of ClassMetadata constant names, i.e.
+NONE, SINGLE_TABLE, INHERITANCE_TYPE_JOINED
+
+## YAML Mapping Driver
+
+The way to specify lifecycle callbacks in YAML Mapping driver was changed to allow for multiple callbacks
+per event. The Old syntax ways:
+
+    [yaml]
+    lifecycleCallbacks:
+      doStuffOnPrePersist: prePersist
+      doStuffOnPostPersist: postPersist
+
+The new syntax is:
+
+    [yaml]
+    lifecycleCallbacks:
+      prePersist: [ doStuffOnPrePersist, doOtherStuffOnPrePersistToo ]
+      postPersist: [ doStuffOnPostPersist ]
+
+## PreUpdate Event Listeners
+
+Event Listeners listening to the 'preUpdate' event can only affect the primitive values of entity changesets
+by using the API on the `PreUpdateEventArgs` instance passed to the preUpdate listener method. Any changes
+to the state of the entitys properties won't affect the database UPDATE statement anymore. This gives drastic
+performance benefits for the preUpdate event.
+
+## Collection API
+
+The Collection interface in the Common package has been updated with some missing methods
+that were present only on the default implementation, ArrayCollection. Custom collection
+implementations need to be updated to adhere to the updated interface.
+
+# Upgrade from 2.0-ALPHA3 to 2.0-ALPHA4
+
+## CLI Controller changes
+
+CLI main object changed its name and namespace. Renamed from Doctrine\ORM\Tools\Cli to Doctrine\Common\Cli\CliController.
+Doctrine\Common\Cli\CliController now only deals with namespaces. Ready to go, Core, Dbal and Orm are available and you can subscribe new tasks by retrieving the namespace and including new task. Example:
+
+    [php]
+    $cli->getNamespace('Core')->addTask('my-example', '\MyProject\Tools\Cli\Tasks\MyExampleTask');
+
+
+## CLI Tasks documentation
+
+Tasks have implemented a new way to build documentation. Although it is still possible to define the help manually by extending the basicHelp and extendedHelp, they are now optional.
+With new required method AbstractTask::buildDocumentation, its implementation defines the TaskDocumentation instance (accessible through AbstractTask::getDocumentation()), basicHelp and extendedHelp are now not necessary to be implemented.
+
+## Changes in Method Signatures
+
+    * A bunch of Methods on both Doctrine\DBAL\Platforms\AbstractPlatform and Doctrine\DBAL\Schema\AbstractSchemaManager
+      have changed quite significantly by adopting the new Schema instance objects.
+
+## Renamed Methods
+
+    * Doctrine\ORM\AbstractQuery::setExpireResultCache() -> expireResultCache()
+    * Doctrine\ORM\Query::setExpireQueryCache() -> expireQueryCache()
+
+## SchemaTool Changes
+
+    * "doctrine schema-tool --drop" now always drops the complete database instead of
+    only those tables defined by the current database model. The previous method had
+    problems when foreign keys of orphaned tables pointed to tables that were schedulded
+    for deletion.
+    * Use "doctrine schema-tool --update" to get a save incremental update for your
+    database schema without deleting any unused tables, sequences or foreign keys.
+    * Use "doctrine schema-tool --complete-update" to do a full incremental update of
+    your schema.
+# Upgrade from 2.0-ALPHA2 to 2.0-ALPHA3
+
+This section details the changes made to Doctrine 2.0-ALPHA3 to make it easier for you
+to upgrade your projects to use this version.
+
+## CLI Changes
+
+The $args variable used in the cli-config.php for configuring the Doctrine CLI has been renamed to $globalArguments.
+
+## Proxy class changes
+
+You are now required to make supply some minimalist configuration with regards to proxy objects. That involves 2 new configuration options. First, the directory where generated proxy classes should be placed needs to be specified. Secondly, you need to configure the namespace used for proxy classes. The following snippet shows an example:
+
+    [php]
+    // step 1: configure directory for proxy classes
+    // $config instanceof Doctrine\ORM\Configuration
+    $config->setProxyDir('/path/to/myproject/lib/MyProject/Generated/Proxies');
+    $config->setProxyNamespace('MyProject\Generated\Proxies');
+
+Note that proxy classes behave exactly like any other classes when it comes to class loading. Therefore you need to make sure the proxy classes can be loaded by some class loader. If you place the generated proxy classes in a namespace and directory under your projects class files, like in the example above, it would be sufficient to register the MyProject namespace on a class loader. Since the proxy classes are contained in that namespace and adhere to the standards for class loading, no additional work is required.
+Generating the proxy classes into a namespace within your class library is the recommended setup.
+
+Entities with initialized proxy objects can now be serialized and unserialized properly from within the same application.
+
+For more details refer to the Configuration section of the manual.
+
+## Removed allowPartialObjects configuration option
+
+The allowPartialObjects configuration option together with the `Configuration#getAllowPartialObjects` and `Configuration#setAllowPartialObjects` methods have been removed.
+The new behavior is as if the option were set to FALSE all the time, basically disallowing partial objects globally. However, you can still use the `Query::HINT_FORCE_PARTIAL_LOAD` query hint to force a query to return partial objects for optimization purposes.
+
+## Renamed Methods
+
+* Doctrine\ORM\Configuration#getCacheDir() to getProxyDir()
+* Doctrine\ORM\Configuration#setCacheDir($dir) to setProxyDir($dir)

-the support for Annotations as Default Driver and require our users to
-specify the driver explicitly (which allows us to ask for the path to all
-entities).
-
-If you are using the annotations metadata driver as default driver, you
-have to add the following lines to your bootstrap code:
-
-    $driverImpl = $config->newDefaultAnnotationDriver(array(__DIR__."/Entities"));
-    $config->setMetadataDriverImpl($driverImpl);
-
-You have to specify the path to your entities as either string of a single
-path or array of multiple paths
-to your entities. This information will be used by all console commands to
-access all entities.
-
-Xml and Yaml Drivers work as before!
-
-
-## New inversedBy attribute
-
-It is now *mandatory* that the owning side of a bidirectional association specifies the
-'inversedBy' attribute that points to the name of the field on the inverse side that completes
-the association. Example:
-
-    [php]
-    // BEFORE (ALPHA4 AND EARLIER)
-    class User
-    {
-        //...
-        /** @OneToOne(targetEntity="Address", mappedBy="user") */
-        private $address;
-        //...
-    }
-    class Address
-    {
-        //...
-        /** @OneToOne(targetEntity="User") */
-        private $user;
-        //...
-    }
-    
-    // SINCE BETA1
-    // User class DOES NOT CHANGE
-    class Address
-    {
-        //...
-        /** @OneToOne(targetEntity="User", inversedBy="address") */
-        private $user;
-        //...
-    }
-    
-Thus, the inversedBy attribute is the counterpart to the mappedBy attribute. This change
-was necessary to enable some simplifications and further performance improvements. We
-apologize for the inconvenience.
-
-## Default Property for Field Mappings
-
-The "default" option for database column defaults has been removed. If desired, database column defaults can
-be implemented by using the columnDefinition attribute of the @Column annotation (or the approriate XML and YAML equivalents).
-Prefer PHP default values, if possible.
-
-## Selecting Partial Objects
-
-Querying for partial objects now has a new syntax. The old syntax to query for partial objects
-now has a different meaning. This is best illustrated by an example. If you previously
-had a DQL query like this:
-
-    [sql]
-    SELECT u.id, u.name FROM User u
-    
-Since BETA1, simple state field path expressions in the select clause are used to select
-object fields as plain scalar values (something that was not possible before).
-To achieve the same result as previously (that is, a partial object with only id and name populated)
-you need to use the following, explicit syntax:
-
-    [sql]
-    SELECT PARTIAL u.{id,name} FROM User u
-
-## XML Mapping Driver
-
-The 'inheritance-type' attribute changed to take last bit of ClassMetadata constant names, i.e.
-NONE, SINGLE_TABLE, INHERITANCE_TYPE_JOINED
-
-## YAML Mapping Driver
-
-The way to specify lifecycle callbacks in YAML Mapping driver was changed to allow for multiple callbacks
-per event. The Old syntax ways:
-
-    [yaml]
-    lifecycleCallbacks:
-      doStuffOnPrePersist: prePersist
-      doStuffOnPostPersist: postPersist
-
-The new syntax is:
-
-    [yaml]
-    lifecycleCallbacks:
-      prePersist: [ doStuffOnPrePersist, doOtherStuffOnPrePersistToo ]
-      postPersist: [ doStuffOnPostPersist ]
-
-## PreUpdate Event Listeners
-
-Event Listeners listening to the 'preUpdate' event can only affect the primitive values of entity changesets
-by using the API on the `PreUpdateEventArgs` instance passed to the preUpdate listener method. Any changes
-to the state of the entitys properties won't affect the database UPDATE statement anymore. This gives drastic
-performance benefits for the preUpdate event.
-
-## Collection API
-
-The Collection interface in the Common package has been updated with some missing methods
-that were present only on the default implementation, ArrayCollection. Custom collection
-implementations need to be updated to adhere to the updated interface.

-# Upgrade from 2.0-ALPHA2 to 2.0-ALPHA3
-
-This section details the changes made to Doctrine 2.0-ALPHA3 to make it easier for you
-to upgrade your projects to use this version.  
-
-## CLI Changes
-
-The $args variable used in the cli-config.php for configuring the Doctrine CLI has been renamed to $globalArguments.
-
-## Proxy class changes
-
-You are now required to make supply some minimalist configuration with regards to proxy objects. That involves 2 new configuration options. First, the directory where generated proxy classes should be placed needs to be specified. Secondly, you need to configure the namespace used for proxy classes. The following snippet shows an example:
-
-    [php]
-    // step 1: configure directory for proxy classes
-    // $config instanceof Doctrine\ORM\Configuration
-    $config->setProxyDir('/path/to/myproject/lib/MyProject/Generated/Proxies');
-    $config->setProxyNamespace('MyProject\Generated\Proxies');
-
-Note that proxy classes behave exactly like any other classes when it comes to class loading. Therefore you need to make sure the proxy classes can be loaded by some class loader. If you place the generated proxy classes in a namespace and directory under your projects class files, like in the example above, it would be sufficient to register the MyProject namespace on a class loader. Since the proxy classes are contained in that namespace and adhere to the standards for class loading, no additional work is required.
-Generating the proxy classes into a namespace within your class library is the recommended setup.
-
-Entities with initialized proxy objects can now be serialized and unserialized properly from within the same application.
-
-For more details refer to the Configuration section of the manual.
-
-## Removed allowPartialObjects configuration option
-
-The allowPartialObjects configuration option together with the `Configuration#getAllowPartialObjects` and `Configuration#setAllowPartialObjects` methods have been removed.
-The new behavior is as if the option were set to FALSE all the time, basically disallowing partial objects globally. However, you can still use the `Query::HINT_FORCE_PARTIAL_LOAD` query hint to force a query to return partial objects for optimization purposes.
-
-## Renamed Methods
-
-* Doctrine\ORM\Configuration#getCacheDir() to getProxyDir()
-* Doctrine\ORM\Configuration#setCacheDir($dir) to setProxyDir($dir)

-# Upgrade from 2.0-ALPHA3 to 2.0-ALPHA4
-
-## CLI Controller changes
-
-CLI main object changed its name and namespace. Renamed from Doctrine\ORM\Tools\Cli to Doctrine\Common\Cli\CliController.
-Doctrine\Common\Cli\CliController now only deals with namespaces. Ready to go, Core, Dbal and Orm are available and you can subscribe new tasks by retrieving the namespace and including new task. Example:
-
-    [php]
-    $cli->getNamespace('Core')->addTask('my-example', '\MyProject\Tools\Cli\Tasks\MyExampleTask');
-
-
-## CLI Tasks documentation
-
-Tasks have implemented a new way to build documentation. Although it is still possible to define the help manually by extending the basicHelp and extendedHelp, they are now optional.
-With new required method AbstractTask::buildDocumentation, its implementation defines the TaskDocumentation instance (accessible through AbstractTask::getDocumentation()), basicHelp and extendedHelp are now not necessary to be implemented.
-
-## Changes in Method Signatures
-
-    * A bunch of Methods on both Doctrine\DBAL\Platforms\AbstractPlatform and Doctrine\DBAL\Schema\AbstractSchemaManager
-      have changed quite significantly by adopting the new Schema instance objects.
-
-## Renamed Methods
-
-    * Doctrine\ORM\AbstractQuery::setExpireResultCache() -> expireResultCache()
-    * Doctrine\ORM\Query::setExpireQueryCache() -> expireQueryCache()
-
-## SchemaTool Changes
-
-    * "doctrine schema-tool --drop" now always drops the complete database instead of
-    only those tables defined by the current database model. The previous method had
-    problems when foreign keys of orphaned tables pointed to tables that were schedulded
-    for deletion.
-    * Use "doctrine schema-tool --update" to get a save incremental update for your
-    database schema without deleting any unused tables, sequences or foreign keys.
-    * Use "doctrine schema-tool --complete-update" to do a full incremental update of
-    your schema.
