We have released Rspamd 1.7.6 today. There are no incompatible changes introduced with this version to our best knowledge.

The most important features and fixes

• Fix multiple neural networks support: it is now possible to learn multiple neural networks with different settings as documented
• Rework rspamadm to use mostly Lua for subcommands for better documentation and extensions support
• Add pubkey checks for dkim_signing module (#2277)
• DMARC reports are now compressed using gzip as suggested by RFC
• Settings module can now skip message processing to improve performance
• Bayes classifier now consider more metatokens from the headers
• ED25519 DKIM signatures are now supported
• Fixed serious issues with composites, maps and other components
• Major memory leak hunting and eliminating (especially those that occurs during reload)
• Add more tests and allow to create fake DNS records to make certain tests self-contained (e.g. DKIM or DMARC)
