Procedural Request: Start maintaining a Change Log

I noticed you guys did a release last month -- and I am updating my build system now to use it.

I am curious -- what went into version 12? Where are the release notes? As much as I love reading commit logs, it would really save some time if the releases were distilled down into a "release notes" or "what's new" list. Can you guys start doing that as part of your release procedure. It would really save me (and maybe others?) tons of time..

Thanks.
