We recommend running in Monolith mode with a PostgreSQL database. - Dendrite has periodic semver releases. We intend to release new versions as we land significant features. - Dendrite supports database schema upgrades between releases. This means you should never lose your messages when upgrading Dendrite. - Breaking changes will not occur on minor releases. This means you can safely upgrade Dendrite without modifying your database or config file. This does not mean: - - Dendrite is bug-free. It has not yet been battle-tested in the real world and so will be error prone initially. - - All of the CS/Federation APIs are implemented. We are tracking progress via a script called 'Are We Synapse Yet?'. In particular, + +- Dendrite is bug-free.
