+  o Major feature (channel):
+    - Remove the incoming and outgoing channel queues. The reason to do so was
+      due to the fact that they were always empty meaning never used but still
+      looked at in our fast path. Bottom line, it was an unused code path.
+    - We've simplify a lot the channel subsystem by removing those queues but
+      also by removing a lot of unused code or dead code around it. Overall
+      this is a cleanup removing more than 1500 lines of code overall and
+      adding very little except for unit test.
+    - The majority ot the channel unit tests have been rewritten and the code
+      coverage has now been raised to 83.6% for channel.c.
+      Closes ticket 23709.
