Hi Daniel,
Here is a rough changelog written from reading through bzr history.
I took a dump of every commit in MariaDB that is not in MySQL 5.1.38, and
wrote this summary of the changes.
I don't have sufficient knowledge to parse through all of the Maria changes
from before MariaDB started. Instead I wrote a generic entry for the Maria
storage engine, and also added entries for what is already written (by Monty I
think) on http://askmonty.org/wiki/index.php/MariaDB_versus_MySQL
So this is probably the best shot we have at a complete list of relevant
differences between MySQL and MariaDB. Do let me know if anyone finds anything
missing or any errors.
Daniel, I hope you can use this as the basis for the release notes.
Maybe this list will also be useful for you to fill out the Manual on the Wiki. I am
thinking you could check that all new features are documented, and add pages
for those that are not. If not trivial, you could just make a stub page and
ask on maria-developers@ for someone to fill them out?
- Kristian.

additional features and bug fixes.
