If you had trouble upgrading to #WriteFreely v0.12 and are running MariaDB, be sure to check out the updated migration notes: https://github.com/writeas/writefreely/releases/tag/v0.12.0
Thanks to @kushal for helping test and verify the fix!
I also changed the notes to reflect that you can easily upgrade from WriteFreely v0.3 or later with the same exact steps. I don't think there are many people on versions that old -- but just in case!
This instance is only for A Bunch Tell projects.
