objects using Closure::bind() and Closure::bindTo().
- Turning null, false or empty string into an object by adding a property
will now emit a warning instead of an E_STRICT error.

fatal error such as "Cannot re-assign auto-global variable GLOBALS".
- Converting array to string now will cause E_NOTICE warning.
- Added multibyte support by default. Now it can be enabled or disabled through
zend.multibyte directive in php.ini.

4. Changes made to existing functions
=====================================
@ -190,22 +197,41 @@ UPGRADE NOTES - PHP 5.4
- fclose() closes streams with resource refcount > 1; it doesn't merely
decrement the resource refcount.
- socket_set_options() and socket_get_options() now support multicast options.
- Arrays cast from SimpleXMLElement now always contain all nodes instead of
just the first matching node.
- All SimpleXMLElement children are now always printed when using var_dump(),
var_export(), and print_r().
- The raw data parameter in openssl_encrypt()/openssl_decrypt() is now an options
integer rather than a boolean. A value of true produces the same behaviour.
- Write operations within XSLT (for example with the extension sax:output) are
disabled by default. You can define what is forbidden with the method
XsltProcess::setSecurityPrefs($options)
XsltProcess::setSecurityPrefs($options).
- Added AES support to OpenSSL.
- openssl_csr_new() expects the textual data to be in UTF-8.
- Added no padding option to openssl_encrypt()/openssl_decrypt().
- Added a "no_ticket" SSL context option to disable the SessionTicket TLS
extension.
- Added new json_encode() options: JSON_PRETTY_PRINT, JSON_UNESCAPED_SLASHES,
JSON_NUMERIC_CHECK, JSON_BIGINT_AS_STRING, JSON_UNESCAPED_UNICODE.
- Added Tokyo Cabinet and Berkley DB 5 support to DBA extension.

supports hashes marked $2a$, $2x$, $2y$ and $2z$.
- mbstring now supports following encodings: Shift_JIS/UTF-8 Emoji,
JIS X0213:2004 (Shift_JIS-2004, EUC-JP-2004, ISO-2022-JP-2004),
MacJapanese (Shift_JIS), gb18030.
- Added encode/decode in hex format to mb_[en|de]code_numericentity().
- Added support for SORT_NATURAL and SORT_FLAG_CASE in array sort functions
(sort, rsort, ksort, krsort, asort, arsort and array_multisort).
