5.0 has reached end-of-life and will no longer receive
bugfixes or security patches from the PHP Project. Some downstream distributions may still continue to provide
backported fixes for a time, depending on their support policy.
Fixed bug #26737 (private/protected properties not serialized when user declared method __sleep() exists). E_NOTICE thrown when __sleep() returns name of non-existing member.

Fixed bug #27628 (Simplify the process of making a POST request via stream context).
Fixed bug #27619 (filters not applied to pre-buffered stream data).
Fixed bug #27519 (Reflection_Function constructor crashes with non-existant function's name).

Fixed numerous bugs with the just-in-time auto-global initialization, that could cause $_SERVER, $argv/$argc and other variables not to work properly.
Fixed data corruption with constant assignments to object properties.
Changed __toString() to be called automatically only with print and echo statements.
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.
Fixed possible crash when internal get_method() is not defined.
Fixed calling methods using call_user_func() in conjunction with the array("Class","Method") syntax to use the scope of the PHP user function.
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.
Fixed getopt() so it works without $_SERVER.
Added support for PHP 4 style object comparisons which is enabled in ze1_compatiblity_mode.
Added support for PHP 4 style object conversion to long, double, and boolean values which is enabled in ze1_compatibility_mode.
Allow object oriented extensions to overload comparison functions and other operations. Solves problems using SimpleXML values.

Improved out of memory handling in new memory manager.
Fixed crash when an object references itself during destructor call.
Fixed crash in foreach() when iterating over object properties or a method's return values.

Timezone specifier
Week specifier
Renamed php.ini option "zend2.implicit_clone" to "zend.ze1_compatibility_mode" as it doesn't only affect implicit cloning.
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.
Fixed crash in php_ini_scanned_files() when no additional INI files were actually parsed.
Fixed bug in gdImageFilledRectangle in the bundled GD library, that required x1 < x2 and y1 < y2 for coordinates.

Fixed bug #27504 (Visibility bugs in call_user_function()).

Completely overhauled SimpleXML extension.
Upgraded bundled SQLite library to version 2.8.11.
Improved destructor implementation to always call destructors on clean shutdown. An order of destruction is not guaranteed.
Redesigned exception support. This fixes many bugs in the previous design such as nested try's and problems with overloaded extensions.
Redesigned clone by adding a clone keyword (clone $obj) and copying all properties before __clone() is called. Also allows calling parent __clone function by using parent::__clone().
Fixed interfaces to check for function return-by-reference equality when inheriting and implementing interfaces.
