-=============================
-1. Reserved words and classes
-=============================

-- **namespace** and **goto** are now reserved keywords.
+========================================
+1. Changes made to default configuration
+========================================

-- **Closure** is now a reserved class. (Used by lambda and closure.)
+- 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:

-=====================================
-2. Changes made to existing functions
-=====================================
+    default_charset = iso-8859-1

-- The HTTP stream wrapper now considers all status codes from 200 to 399 to be
-  successful.
+  to your php.ini to preserve pre-PHPX.Y behavior

-- The array functions natsort(), natcasesort(), usort(), uasort(), uksort(),
-  array_flip(), and array_unique() no longer accept objects passed as arguments.
-  If you need to use them to access an object's properties, you must cast the
-  object to an array first.
+=============================
+2. Reserved words and classes
+=============================

-- var_dump() output now includes private object members.
+-

-- session_start() now returns FALSE when the session startup fails.
+=====================================
+3. Changes made to existing functions
+=====================================

-- property_exists() now checks the existence of a property independent of
-  accessibility (like method_exists()).
+-

-- The $initial parameter for array_reduce can now be of any type.
-
-- clearstatcache() no longer clears the realpath cache by default.
-
-- realpath() is no longer system-dependent and works identically on all
-  platforms.
-
-- call_user_func() now propagates $this even if the callee is the parent class.
-
-- The filesystem functions opendir(), scandir(), and dir() now use the default
-  context if no context argument is passed.
-
-- The behaviour of functions with by-reference parameters called by value has
-  changed. Where previously the function would accept the by-value argument, a
-  warning is now emitted and all by-ref parameters are set to NULL.
-
-- There is now native support for the following math functions: asinh(),
-  acosh(), atanh(), log1p(), and expm1().
-
-- In the GD extension, there is now pixelation support available through
-  the imagefilter() function.
-
-- crypt() now has Blowfish and extended DES support, and crypt() features are
-  now 100% portable. PHP has its own internal crypt implementation which drops
-  into place when system support for crypt or crypt_r() is not found.
-
-- get_cfg_var() is now able to return "array" INI options.
-
-- Stream wrappers can now be used by the include_path INI directive.
-
-- These functions now take new parameters:
-     clearstatcache(): $clear_realpath_cache and $filename.
-     copy(): $context
-     fgetcsv(): $escape
-     ini_get_all(): $details
-     json_encode(): $options
-     json_decode(): $depth
-     nl2br(): $is_xhtml
-     parse_ini_file(): $scanner_mode
-     round(): $mode
-     stream_context_create(): $params
-     strstr(), stristr(): $before_needle
-     sybase_connect(): $new
-
-- And new mode option for fopen: 'n' (O_NONBLOCK)
-
-- The new mysqlnd library necessitates using MySQL's newer 41-byte password
-  format. Continued use of the old 16 byte passwords will cause mysql_connect()
-  and other related functions to produce the following error message:
-  "mysqlnd cannot connect to MySQL 4.1+ using old authentication"
-
-- The dl() function is now disabled by default, and only available under the
-  cli, cgi, and embed SAPIs.
-
-- mail() now supports the logging of sent mail.
-
-- stream_select(), stream_set_blocking(), stream_set_timeout(), and
-  stream_set_write_buffer() now work with user-space stream wrappers.
-
-- getopt() accepts "long options" now on all platforms.
-  Optional values and using = as a separator for short options are now
-  supported.
-
-
 ===================================
-3. Changes made to existing methods
+4. Changes made to existing methods
 ===================================

-- The magic methods __get(), __set(), __isset(), __unset(), and __call() should
-  always be public and can no longer be static. Method signatures are enforced.
+-

-- The __call() magic method is now invoked on access to private and protected
-  methods.
-
-- The __toString() magic method can no longer accept arguments.
-
-- There is a new magic method, __callStatic().
-
-- Internal count() vs. count_elements() handler resolution rules have changed.
-  (This could potentially break custom PHP extensions.)
-
-- The trailing / has been removed from SplFileInfo and other related directory
-  classes.
-
-- SplFileInfo::getpathinfo() now returns information about the path name.
-
-- There are new parameters in:
-     Exception::__construct(): $previous
-
 ===================================
-4. Changes made to existing classes
+5. Changes made to existing classes
 ===================================

-- SplObjectStorage now has ArrayAccess support. It is also now possible to
-  store associative information with objects in SplObjectStorage.
+-

 =============

-
-- mysql_listtables(), mysql_dropdb(), mysql_createdb(), mysql_list_tables(),

-
-- All ereg functions are now deprecated and emit E_DEPRECATED errors:
-  sql_regcase(), spliti(), split(), ereg_replace(), eregi(),
-  ereg_replace(), and ereg().
-  Use the PCRE family of functions (preg_*()) instead.
-

 7. Extensions:
 ==============

      a. moved out to PECL and actively maintained there

-        - fdf
-        - ming
-        - ncurses
+        -

      b. no longer maintained

-        - dbase
-        - fbsql
-        - msql
-        - sybase (use sybase_ct, which is still in PHP core)
-        - mhash (hash has full BC layer)
-        - mime_magic (use fileinfo, has full BC layer)
+        -

      c. with changed behaviour

-        - dns: dns_check_record() will now return an extra "entries" index,
-          containing the TXT elements.
+        -

-        - datetime: date/time functions will no longer use the TZ environment
-          variable to guess which timezone should be used.
-
-        - cURL now supports SSH
-
-        - hash: The SHA-224 and salsa hash algorithms are now supported.
-
-        - mbstring: Now supports CP850 encoding.
-
-        - oci8: Database Resident Connection Pooling (DRCP) and Fast Application
-          Notification (FAN) are now supported.

-
-          The oci8 function oci_bind_by_name() now supports SQLT_AFC (aka the
-          CHAR datatype).
-
-          Calling oci_close() on a persistent connection, or when the variable
-          that references a persistent connection goes out of scope, will now
-          trigger a roll back of an uncommitted transaction. To avoid unexpected
-          behavior explicitly issue a commit or roll back as needed. The old
-          behavior can be enabled with the INI directive

-        - SOAP: Now supports sending user-supplied HTTP headers.
-
-        - MySQLi: Now supports persistent connections by prepending the hostname

-
      d. no longer possible to disable

-        - PCRE
-        - Reflection
-        - SPL
+        -

 ==========================
 8. Changes in SAPI support
 ==========================

-- A new "litespeed" SAPI is now available.
+-

-- FastCGI is now always enabled and can not be disabled. See sapi/cgi/CHANGES
-  for more details.
-
-- A new CGI SAPI option, -T, can be used to measure execution time of a script
-  repeated several times.
-
-- CGI/FastCGI now has support for .htaccess style user-defined php.ini files.
-  See the new user_ini.filename and user_ini.cache_ttl INI directives.
-
 ============================
 9. Changes in INI directives
 ============================

-- zend_extension_debug and zend_extension_ts have been removed. Always use the
-  zend_extension directive to load Zend Extensions.
+-

-  on, then an E_ERROR is emitted at startup.
-
-- There is now support for special sections: [PATH=/opt/httpd/www.example.com/]
-  and [HOST=www.example.com]. Directives set in these sections cannot be
-  overridden by user-defined INI files or at runtime.
-

-
-- A new directive, request_order, controls the behavior of $_REQUEST
-  independently of variables_order.
-

-
 ====================
 10. Syntax additions
 ====================

-- NOWDOC: Similar to HEREDOC, but with single quotes:
+-

-      <<<'LABEL' ...
-
-  Static HEREDOCs can be used to initialize static variables and class members
-  or constants:
-
-      static $foo = <<<LABEL
-      No variables here...
-      LABEL;
-
-- HEREDOC now supports wrapping the identifier with double-quotes, to complement
-  the NOWDOC syntax:
-
-      <<<"LABEL" ...
-
-- The ?: operator has been introduced:
-
-      var_dump(0 ?: 'Hello!');
-
-- Namespaces were added:
-
-      namespace my\name;
-      $obj = new \my\name\MyClass;
-
-- Dynamic access to static methods is now possible:
-
-      $foo::myFunc();
-
-- Exceptions can now be nested:
-
-      class MyCustomException extends Exception {}
-      try {
-          throw new MyCustomException("Something happend", 112);
-      } catch(Exception $e) {
-          throw new InvalidArgumentException("You are doing it wrong!", 911, $e);
-      }
-
-- Exceptions can now be handled in destructors.
-
-- A garbage collector has been added and is enabled by default.
-
 ===================
 11. Windows support
 ===================

-- The minimum Windows version is now Windows 2000. (Windows 98, ME and NT4 are
-  no longer supported).
+-

-- PHP Windows binaries target i586 or later. i386 and i486 are not supported.
-
-- Support for the IIS SAPI has been dropped. Use the FastCGI SAPI instead
-  (available for IIS5 and later)). FastCGI is the recommended way to use PHP
-  with IIS (see http://php.iis.net/).
-
-- A new build is available based on the latest Visual C++ Compiler (VC9).
-  Its use is recommended with FastCGI or CLI. Apache's Windows binaries are not
-  compatible with VC9; however, you can use Apache Lounge's build
-  (http://apachelounge.com).
-
-- The x64 binaries are for experimental usage only. They are not meant to be
-  used in production.
-
-- A new site is available to download Windows releases as well as Windows-only
-  releases: http://windows.php.net. Windows-specific releases will be made to
-  fix security issues in the bundled libraries (libpng, openssl, etc.). Please
-  note that this site does not replace the main PHP site as a source of PHP
-  news, resources, or documentation.
-
-- Windows support has been added for the following functions: getopt(),
-  imagecolorclosesthwb(), mcrypt_create_iv(), inet_ntop(), inet_pton(),
-  getmxrr(), checkdnsrr(), dns_get_record(), linkinfo(), readlink(),
-  symlink(), link(), fnmatch(), stream_socket_pair(), time_nanosleep(),
-  time_sleep_until(), and socket_create_pair().
-
-- Crypt supports now all available algorithms on Windows (blowfish included).
-
-- Improved portability of stat(), touch(), filemtime(), filesize() and related
-  functions (100% portable for the available data).
-
-- It is now possible to create hard links on Windows using the link() function,
-  and symbolic links using the symlink() function. Hard links are available
-  as of Windows 2000 and symbolic links as of Windows Vista.
-
-- The PDO_OCI php_pdo_oci8.dll library (for use with Oracle version 8 client
-  libraries) is no longer being built. Instead, use php_pdo_oci.dll (note no
-  '8') with Oracle 10 or 11 client libraries. Connection to other database
-  versions is still supported.
-
-- For the OCI8 extension, a new library php_oci8_11g.dll is available in
-  addition to php_oci8.dll. Only one can be enabled at any time. Use
-  php_oci8.dll with Oracle 10.2 client libraries. Use php_oci8_11g.dll with
-  Oracle 11 client libraries. Connection to other database versions is still
-  supported.
-
-- Firebird and SNMP support are no longer available on Windows. Firebird support
-  may be reintroduced in the future.
