Should any of the following have a CHANGES note?:
* ADT.Heap: Added low_peek().
* Fix GTK2.SourceBuffer undo/redo signal names * Fix spelling of composite[d]_changed signal - Is that an API change or where the signals not properly hooked up before?
* Crypto/SSL
- There is a ton of Crypto/SSL changes. I'm just going to trust Nilsson and/or Grubba to make sure relevant things are in CHANGES.
