+Codecs
+------------------
+ * Added the associated format name to 'core show codecs'.
+
+res_ari_channels
+------------------
+ * Added 'formats' to channel create/originate to allow setting the allowed
+   formats for a channel when no originator channel is available.  Especially
+   useful for Local channel creation where no other format information is
+   available.  'core show codecs' can now be used to look up suitable format
+   names.
