Hi!
We arey happy to release Dovecot v2.4.1!
Some IMPORTANT things to notice (still):
- We have changed the signing key for 2.4 going forward, releases are signed with EF0882079FD4ED32BF8B23B2A1B09EF84EDC5219, which can be found at https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4 and is signed with the previous key.
The old key has been renamed to https://repo.dovecot.org/DOVECOT-REPO-GPG-2.3.
New 2.4 packages **are not** compatible with old 2.3 configuration, please carefully review https://doc.dovecot.org/2.4.1/installation/upgrade/2.3-to-2.4.html before installing the new packages.
We are happy to provide experimental arm64 support in the form of a Docker image. There are now three kinds of images, latest, latest-dev and latest-root.
The latest docker image is now ran rootless, with UID 1000 as vmail. Please take this into consideration when upgrading. The latest-root image still runs as root. Latest 2.3 image can be used with tag 2.3-latest still
We won't be sending separate mail about Pigeonhole anymore as we will release one anyways when we release Dovecot, and Pigeonhole versioning has been changed to match Dovecot versioning.
