PHP X.Y UPGRADE NOTES

1. Backward Incompatible Changes
2. New Features
2. Changes in SAPI modules
3. Deprecated Functionality
4. Changed Functions
5. New Functions
6. New Classes and Interfaces
7. Removed Extensions
8. Other Changes to Extensions
9. New Global Constants
10. Changes to INI File Handling
11. Other Changes


========================================
1. Backward Incompatible Changes
========================================

- Drop Windows XP and 2003 support. (Pierre)

========================================
2. New Features
========================================

- Support constant array/string dereferencing. (Laruence)
  (https://wiki.php.net/rfc/constdereference)
- Add support for using empty() on the result of function calls and
  other expressions. Thus it is now possible to write empty(getArray()),
  for example. (https://wiki.php.net/rfc/empty_isset_exprs)

========================================
2. Changes in SAPI modules
========================================


========================================
3. Deprecated Functionality
========================================

- The preg_replace /e modifier is now deprecated.  Use
  preg_replace_callback instead.
  (https://wiki.php.net/rfc/remove_preg_replace_eval_modifier)

========================================
4. Changed Functions
========================================

- pack()/unpack() had the following changes, which bring it more in line
  with Perl's behavior:
  - Implemented format character "Z": NUL-padded string
  - "a" now does not remove trailing NUL characters on unpack() anymore
  - "A" will now strip all trailing ASCII whitespace on unpack() (it used to
    remove only trailing spaces).
- MessageFormatter::format() and related functions now accepted named arguments
  and mixed numeric/named arguments in ICU 4.8+.
- MessageFormatter::format() and related functions now don't error out when
  an insufficient argument count is provided. Instead, the placeholders will
  remain unsubstituted.
- MessageFormatter::parse() and MessageFormat::format() (and their static
  equivalents) now don't throw away better than second precision in the
  arguments.
