--------------------------
* Added setvar option to calendar.conf to allow setting channel variables on
notification channels.
+
+MixMonitor
+--------------------------
+ * Added two new options, r and t with file name arguments to record
+ single direction (unmixed) audio recording separate from the bidirectional
+ (mixed) recording. The mixed file name argument is optional now as long
+ as at least one recording option is used.
