j. New hash algorithms
========================================
1. Changes made to default configuration
========================================
- The default_charset setting now defaults to UTF-8.
It was ISO-88590-1 before, so if you were relying
on the default, you will need to add:
default_charset = iso-8859-1
to your php.ini to preserve pre-PHPX.Y behavior.
- We now check at compile time if /dev/urandom or /dev/arandom
are present to provide non-blocking entropy to session id
generation. If either is present, session.entropy_file
now defaults to that file and session.entropy_length defaults
to 32. If you do not want extra entropy for your session ids
for some reason, add:
session.entropy_file=
session.entropy_length=0
to your php.ini to preserve pre-PHPX.Y behavior.
- Deprecated ini directives will now throw an E_CORE_WARNING's
instead of the previous E_WARNING's.
The following directives are marked as deprecated:
- magic_quotes_gpc
- magic_quotes_runtime
- magic_quotes_sybase
- The following directives, which indicates a removed feature
in PHP will now throw an E_CORE_ERROR upon startup like the
deprecation warnings.
The following directives are no longer available:
- allow_call_time_pass_reference
- define_syslog_variables
- highlight.bg
- register_globals
- register_long_arrays
- safe_mode
- safe_mode_gid
- safe_mode_include_dir
- safe_mode_exec_dir

- safe_mode_protected_env_vars
- zend.ze1_compatibility_mode
=============================
2. Reserved words and classes
=============================
-
=====================================
3. Changes made to existing functions

- array_combine now returns array() instead of FALSE when two empty arrays are
provided as parameters.

4. Changes made to existing methods
===================================
-
===================================
5. Changes made to existing classes
