support; systems using that compiler will need to be upgraded to

+Dialplan Expressions:

+* The dialplan expression parser (which handles $[ ... ] constructs)
+ has gone through a major upgrade, but has one incompatible change:
+ spaces are no longer required around expression operators, including
+ string comparisons. However, you can now use quoting to keep strings
+ together for comparison. For more details, please read the
+ doc/README.variables file, and check over your dialplan for possible
+ problems.

Agents:
* The default for ackcall has been changed to "no" instead of "yes"
