<h3>December 24 1998, Version 3.0.6</h3>
<ul>
<li> Fix GetImageSize() to work with non-standard jpg images
<li> Add Mersenne Twister functions (mt_rand, mt_srand, etc)
<li> Add str_replace() function
<li> Add chunk_split() function
<li> Fixed a bug in the memory limit code, in cases where $php_errormsg was
  also used.
<li> Add iptcparse() function
<li> Adobe FDF supported
<li> getallheaders() NULL string fix &lt;michale@utko.fee.vutbr.cz&gt;
<li> Add all configuration directives to phpinfo() page
<li> Functions pack() and unpack() rewritten to be binary and buffer overrun
  safe and behave like the Perl functions for all implemented format codes.
<li> Ensured that msql_error() will not return error messages generated by
  previously-run scripts.
<li> Add base_convert() function
<li> Make sprintf() and printf() output binary safe
<li> Made gzgetc binary safe
<li> Add convert_cyr_string() and quoted_printable_decode() functions
<li> Fix ldap_free_result() core dump bug
<li> Add support for current OpenLDAP-2.0-devel library
<li> Add php3_asp_tags directive so it can be set from Apache config files
<li> Added UTF-8 support in the XML extension
<li> Make rand(min,max) safer on older platforms where the low-order bits have 
  short cycles.
<li> Added new pdf (Portable Document Format) module
<li> Added an XML parsing extension using James Clark's "expat" library
<li> Optimized parts of the token cache code.
<li> Terminate on out-of-memory errors.  Until now, PHP could crash in out of
  memory situations (clean-up, no real effect).
<li> Unterminated comments in include files were being reported with the wrong line
  number.  Fixed.
<li> Added ImageCopy() and ImageColorDeallocate(). ImageCopy() is about
  20% faster than ImageCopyResized(). ImageColorDeallocate() marks
  palette entries free for reuse (by &lt;mka@satama.com&gt;).
<li> In the CGI version, it was impossible to access resources (e.g. SQL links,
  images) from user-defined shutdown functions.  Fixed.
<li> Added optional third parameter to strpos() to specify the offset to
  start searching from.
<li> Fixed a crash bug in unset() when unsetting illegal variables (rare).
<li> Made ImageInterlace and ImageTransparentColor parameters optional, and made
  them return the current/new settings.
<li> Optimized GetImageSize() &lt;thies@digicol.de&gt;.
<li> Made odbc_autocommit() without args return status
<li> Added connect workaround for OpenLink ODBC
<li> Added minimal InterBase support. Tested only on 4.0 & Linux.
<li> Fixed some memory leaks and bogus error messages in the URL handler of
  the various file open functions.  Should only affect error handling
  in bad URLs.
<li>Added support for Empress RDBMS using unified ODBC inteface and Empress
  ODBC client driver (for Empress v8.10 and above).
</ul>

<h3>October 5 1998 Version 3.0.5</h3>
<ul>
<li> mysql_field_flags now reports all MySQL flags and the result is suitable
  for automatic parsing. Compatibility warning: The result format has
  changed. If you have scripts parsing the result of this function, you
  may need to adapt them.
<li>Made nl2br() binary safe (not that it's of much use).
<li>Fixed a bug in the API function getThis().  It affected mostly the dir
  functions, if nested within objects.
<li>Fixed a problem in require() in conjunction with switch(), and in some other
  cases.  Also fixed an identical problem with the call_user_function() API
  function.
<li>Removed -lpthread when compiling with MySQL support.  It caused various
  serious problems when compiled into Apache.
<li>Add serialize() and unserialize() functions from jkl@njet.net
<li>Fix in_addr_t check for systems with in_addr_t in netinet/in.h
<li>Add atan2() function
</ul>

<h3>Sept. 22, 1998 Version 3.0.4</h3>
<ul>
<li> Added uksort() - array key sort using a user defined comparison function.
<li> Added 'j' support to date() - generates the day of the month, without
  possible leading zeros.
<li> Added support for multiple crypt() encryptions if the system supports it
<li> Added optional support for ASP-style &lt;% %&gt; and &lt;%= tags
<li> Fixed data loss problems with very large numeric array indices on 64-bit
  platforms (e.g. DEC UNIX).
<li> 2 cursor_type parameters for ifx_query() and ifx_prepare changed
  to 1 (bitmask). Added a few constants for use in Informix module.
<li> Added php3.ini option ifx.charasvarchar. If set, trailing blanks
  are stripped from fixed-length char columns. (Makes life easier
  for people using Informix SE.)
<li> Static SNMP module which compiles with ucd-snmp 3.5.2
<li> fixed imap_header & header_info from crashing when a header line
  is > 1024 characters.
<li> Added patch for rfc822_parse_adr to return an array of objects instead
  of a single object.
<li> Informix Online 7.x & SE 7.x support now fairly complete and stable
<li> Add dbase_get_record_with_names() function
<li> Added a special case for open_basedir. When open_basedir is set to "."
  the directory in which the script is stored will be used as basedir.
<li> Include alloca.c in the distribution for platforms without alloca().
<li> Improved stripping of URL passwords from error messages - the length of the
  username/password isn't obvious now, and all protocols are handled properly
  (most importantly, http).
<li> Copying objects that had member functions with static variables produced
  undetermined results.  Fixed.
<li> Added function lstat() and cleaned up the status functions,
  added tests for file status functions (this may break on some plattforms)
<li> Fixed is_link() - it was returning always false.
<li> Fixed apache_note() - it was corrupting memory.
<li> New Function.  void get_meta_tags(string filename);  Parses filename until
  closing head tag and turns all meta tags into variables prefixed with 'meta_'.
  The below meta tag would produce $meta_test="some string here"<br>
    &lt;meta name="test" content="some string here"&gt;
<li> Generalized some internal functions in order to better support calling
  user-level functions from C code.  Fixes a few sporadic problems related
  to constructors inside eval() and more.
<li> Fixed an endless loop in explode(), strstr() and strpos() in case of an
  invalid empty delimiter.
<li> rand() now accepts two optional arguments, which denote the requested range
  of the generated number.  E.g., rand(3,7) would generate a random number
  between 3 and 7.
<li> Added M_PI constant.
<li> Added deg2rad() and rad2deg() for converting radians&lt;-&gt;degrees.
<li> ImageArc() misbehaved when given negative angles, fixed.
<li> Fixed a bug in ereg() that may have caused buglets under some circumstances.
<li> Added imap_status
<li> Shutdown functions, registered via register_shutdown_function(), could never
  generate output in the Apache module version.  Fixed.
<li> Brought IMAP docs into sync with acutal imap code
<li> imap_fetchstructure now takes in optional flags
<li> Fix potential core dumps in imap_append and imap_fetchtext_full
<li> Fix problem in SetCookie() function related to long cookies
<li> Add uasort() function to go along with usort (like sort() and asort())
<li> Add port number to Host header as per section 14.23 of the HTTP 1.1 RFC
<li> Fix imap_reopen to only take 2 arguments with an optional 3rd flags arg
<li> Add optional 2nd argument to imap_close
<li> Add CL_EXPUNGE flag to imap_open() flags
<li> Fix 4th arg on imap_append().  It was getting converted to a long by mistake.
<li> Fix shutdown warning in the LDAP module
<li> *COMPATIBILITY WARNING* imap_fetchstructure() "parametres" object and property
  name changed to "parameters" to match the documentation and to be consistent
  with the rest of the API.
<li> Delete uploaded temporary files automatically at the end of a request
<li> Add upload_max_filesize and correponsing php3_upload_max_filesize directive
  to control the maximum size of an uploaded file.  Setting this to 0 would
  completely eliminate file uploads.
<li> Force $PHP_SELF to PATH_INFO value when running in CGI FORCE_CGI_REDIRECT mode
<li> Add apache_lookup_uri() function which does an internal sub-request lookup
  and returns an object containing the request_rec fields for the URI.  (Yes,
  you have to be a bit of a gearhead to figure this one out)
<li> Fix a few signed char problems causing functions like ucfirst() not to work
  correctly with non-English charsets
<li> md5() function not binary safe - fixed
</ul>

<h3>August 15, 1998 Version 3.0.3</h2>
<ul>
<li> Changed the name of fopen_basedir to open_basedir, to be a little more
  accurate about what it does.
<li> Added Hyperwave module
<li> Added config-option (php3_)enable_dl &lt;on/off&gt;. This enables/disables the
  dl() function.  In safe-mode dl() is always disabled.
<li> Auto-prepended files were crashing under some circumstances - fixed.
<li> Win32 mail fixes provided by walton@nordicdms.com
<li> Comparing between arrays and/or objects now generates a warning (it always
  returns false, as it used to;  no comparison is made)
<li> Fixed a bug in the syntax highlighting code, that made ending-double-quotes
  appear twice under certain circumstances.
<li> Fix bug in filetype() function related to symlinks
<li> Started integrating Informix SE support to PHP configure/makefile setup.
<li> gdttf roundoff fixes from ellson@lucent.com
<li> Added initial Informix SE support files from Danny Heijl - This code still
  needs to be integrated into the PHP configure/makefile setup and the code
  itself needs more work.
<li> return in the global scope now terminates the execution of the current file.
<li> Added the ability to register shutdown function(s), via
  register_shutdown_function($function_name).
<li> Clean up const warnings
<li> Add write support to ftp fopen wrappers
<li> Add strspn() and strcspn() functions
<li> On systems without strerror use Apache version if compiling as Apache module
<li> The PHP start tag was being ignored under some circumstances - fixed.
<li> The db, dbase and filepro functions are now Safe-Mode aware.
<li> Added config-option (php3_)fopen_basedir &lt;path&gt;. This limits the directory-
  tree scripts can open files in to &lt;path&gt;.
<li> Fixed pg_loreadall that didn't always return all the contents in a PostgreSQL
  large object. Also, doesn't pass through anything if method is HEAD.
<li> configure fix to create target Apache module dir
<li> Fix core dump in imageTTFtext() function
<li> Added static IMAP support
<li> Syntax highlighting was generating additional whitespace - fixed.
<li> Added ucwords.  Works like ucfirst, but works on all words within a string.
<li> Added array_walk() - apply user function to every element of an array
<li> Added usort() - array sort that accepts a user defined comparison function!
<li> Added the ability to call user-level functions and object methods on demand
  from the C source using a completely generalized, slick API function.
  Miracles do happen every once in a while.
<li> Added constructors.  Don't even squeek about destructors! :) (we mean that)
<li> Make pg_lowrite() binary safe
<li> Fixed mod_charset option in ./setup
<li> Fixed rewinddir() and dir()::rewind() under Win32 (they didn't work before).
<li> Add Win32 COM support!  By-name referencing is supported using the IDispatch
  interface (automation).  Available functions - COM_Load(), COM_Invoke(),
  COM_PropGet() and COM_PropSet().

  getting truncated when having large values.
<li>Added testpages for unified odbc
<li>Fix php -s seg fault when filename was missing
<li>Made getdate() without args default to current time
<li>Added ImageColorResolve() and some fixes to the freetype support.

  to make it possible to configure the look of error messages displayed by PHP
  to some extent

  used in conjunction with error_reporting()
  (e.g. error_reporting(E_ERROR|E_WARNING|E_NOTICE);
<li>Fixed a crash problem with classes that contained function(s) with default
  values.
<li>Fixed a problem in the browscap module.  Browscap files weren't being read
  properly.
