Looks like Friday the 13th isn't the best day to make releases. :) These releases fix two bad bugs in v1.1.12.

- v1.1.12's MAILBOXDIR changes broke accessing mails in some setups
- v1.1.12's login_executable -D checking changes caused dovecot to
  crash at startup if protocols setting contained only pop3.
- mbox: pop3_lock_session=yes was broken with mail_privileged_group.
