Rspamd 3.4 has been released

We have released Rspamd 3.4 today. This is a bugfix release with no incompatible changes. Several new features have also been added. Here are the most important changes in this version explained.

Main changes

Hyperscan databases are now shared between all Rspamd processes reducing memory footprint, especially when multiple worker processes are running.

Critical fix in the compatibility with the integrations and headers alterations

There was a critical compatibility issue, caused by the change in the milter_headers reply block that prevents some Rspamd integrations to be functional. In this release that issue has been fixed, and the compatibility with the previous output format has been restored.

Fix additional fields in the Redis schema

Some fields were no longer accepted in Redis settingsissue. Now it works correctly.
