Skinny channels only.
* You can now compile Asterisk against the Hoard Memory Allocator, see doc/hoard.txt
for more information.
+ * Config file variables may now be appended to, by using the '+=' append
+ operator. This is most helpful when working with long SQL queries in
+ func_odbc.conf, as the queries no longer need to be specified on a single
+ line.

* queues.conf: the queue-lessthan sound file option is no longer available, and the
queue-round-seconds option no longer takes '1' as a valid parameter.
+* If you have any third party modules which use a config file variable whose
+ name ends in a '+', please note that the append capability added to this
+ version may now conflict with that variable naming scheme. An easy
+ workaround is to ensure that a space occurs between the '+' and the '=',
+ to differentiate your variable from the append operator. This potential
+ conflict is unlikely, but is documented here to be thorough.

* Manager has been upgraded to version 1.1 with a lot of changes.
