mailu/CHANGELOG.md

Changelog
=========

Upgrade should run fine as long as you generate a new compose or stack
configuration and upgrade your mailu.env.

There are some changes to the configuration overrides. Override files are now mounted read-only into the containers.
The Dovecot and Postfix overrides are moved in their own sub-directory.
If there are local override files, they will need to be moved from overrides/ to overrides/dovecot and overrides/postfix/.
See https://mailu.io/1.8/faq.html#how-can-i-override-settings for all the mappings.

One major change for the docker compose file is that the antispam container needs a fixed hostname [#1837](https://github.com/Mailu/Mailu/issues/1837).
This is handled when you regenerate the docker-compose file. A fixed hostname is required to retain rspamd history. 
This is also handled in the helm-chart repo.

Please not that the shipped image for PostgreSQL database is deprecated.
We advise to switch to an external PostgreSQL database server.
