Hi!
We are happy to publish version 2.4.3 of Dovecot and Pigeonhole. These contain several CVEs, discovered by external researches. The majority of these have been discovered with help of automated code analysis tools like claude code security, which is why some of these are rather old, missed bugs.
No new supported distros have been added or old removed, no new dependencies have been added.
Note that there are experimental features in 2.4, one is enabled with
--enable-experimental-mail-utf8, and another with--enable- experimental-imap4rev2, and you also need to set mail_utf8_extensions=yes and imap4rev2_enabled=yes to enable them in config.
Thank you Aki - I think there may be a typo in the announce:
imap4rev2_enabled=yes
should probably be:
imap4rev2_enable=yes
