1. Backward Incompatible Changes
========================================
- Core
. Bitwise shifts by negative numbers of bits are disallowed (throws E_WARNING
and gives FALSE, like a division by zero).
. Left bitwise shifts by a number of bits beyond the bit width of an integer
will always result in 0, even on CPUs which wrap around.
. Right bitwise shifts by a number of bits beyond the bit width of an integer
will always result in 0 or -1 (depending on sign), even on CPUs which wrap
around.
- DBA
. dba_delete() now returns false if the key was not found for the inifile
handler, too.

13. Other Changes
========================================
- Core
. Instead of being undefined and platform-dependant, NaN and Infinity will
always be zero when casted to integer.
- Standard
. call_user_method() and call_user_method_array() no longer exists.
