?? March 2004, PHP 5 Release Candidate 1
- Fixed bug #27457 (handling of numeric indexes in strtr()). (Dmitry)
- Replaced the exec_finished hook by the zend_post_deactive hook for
  extensions. The new hook will be run after the symbol table and destructors
  are run. (Derick)
- Fixed possible crash when internal get_method() is not defined. (Andi)
- Fixed calling methods using call_user_func() in conjunction with 
  the array("Class","Method") syntax to use the scope of the PHP user function.
  (Dmitry)
- Fixed php-cgi to not ignore command-line switches when run in a web context.
  This fixes our test cases allowing INI with GET sections to work. (Rasmus)
- Fixed getopt() so it works without $_SERVER. (Rasmus, bfrance)
- Added support for PHP 4 style object comparisons which is enabled in
  ze1_compatiblity_mode. (Andi)
- Added support for PHP 4 style object conversion to long, double, and boolean
  values which is enabled in ze1_compatibility_mode. (Andi, Stas)
- Allow object oriented extensions to overload comparison functions and other
  operations. Solves problems using SimpleXML values. (Andi, Zeev)
- Fixed crash when accessing a class constant with a value which in turn is
  also a constant. (Dmitry)
- Fixed object's truth value conversion. It is always true unless
  ze1_compatibility_mode is on in which it behaves like in PHP 4. (Stas)
- Improved out of memory handling in new memory manager. (Stas)
- Fixed crash when an object references itself during destructor call. (Andi)
- Fixed crash in foreach() when iterating over object properties or a method's
  return values. (Andi)
- Fixed crash when an exception is thrown in a destructor. Such exceptions are
  now ignored as destruction happens out of context at no definite time. (Andi)
- Fixed crashes in exception handling. (Dmitry, Andi)
- Changed prototype checks so that they aren't done on constructors. (Andi)
- Changed prototype checks to output an E_STRICT message instead of
  an E_COMPILE_ERROR. (Andi)
- Changed Iterator::has_more() to Iterator::valid(). (Marcus)
- Upgraded bundled oniguruma library to version 2.2.2. (Rui, Moriyoshi)
- Added mb_list_encoding() to return an array with all mbstring supported
  encodings. (Derick)
- Added support for more ISO8601 datetime formats in strtotime(). (Moriyoshi)
  . Timezone specifier (ex. "20040301T02:00:00+19:00")
  . Week specifier (ex. "1997W021")
- Renamed php.ini option "zend2.implicit_clone" to 
  "zend.ze1_compatibility_mode" as it doesn't only affect implicit cloning.
  (Andi, Zeev)
- Methods that override parent methods are now subject to prototype checking,
  and have to be compatible with the method they're overriding - this check is 
  disabled in compatibility mode. (Andi, Zeev)
- Fixed crash in php_ini_scanned_files() when no additional INI files were
  actually parsed. (Jon)
- Fixed bug in gdImageFilledRectangle in the bundled GD library, that required
  x1 < x2 and y1 < y2 for coordinates. (Derick)
- Fixed crash with foreach() and temporary objects($obj->method()->a ...) where
  method returns a non-referenced object. (Andi, Zeev)
- Fixed problem preventing startup errors from being displayed. (Marcus)
- Fixed start-up problem if both SPL and SimpleXML were enabled. The double
  initialization of apache 1.3 was causing problems here. (Marcus, Derick)
- Fixed bug #27606 (Expression must be a modifiable lvalue compiler error).
  (Derick)
- Fixed bug #27597 (pg_fetch_array not returning false). (Marcus)
- Fixed bug #27586 (ArrayObject::getIterator crashes with [] assignment).

  values / objects). (Moriyoshi)

- Fixed bug #27227 (Mixed case class names causes Fatal Error in Constructor 
  call). (Marcus)
