Interesting job was done in this release with 3 new features:

- Support for XOAUTH2;
- New 'tls_level' configuration option to automatically discard insecure SSL protocols;
- New interface 'syslog' comes in, next to the -s CLI option. This allows better
  integration with systemd.

I won't merge big changes until the stable is out. IOW, you can seriously start
testing this rc2.

As explained in the README, I'm currently putting all my efforts into imapfw.
Hence, I plan to do the "minimal" maintenance work for OfflineIMAP. Experimented
users are very welcome to help others since I'll be afk for this kind of topic.
At github, I've marked issues I won't work on with the new "need contributor"
tag. A pending topic needs love in the pull requests so a maintainer can merge.
