Open-source Matrix homeserver for secure decentralized real-time messaging

element.io ↗

Synapse keeps a fixed release train: one minor a fortnight, patches in between.

matrixself-hostingrelease-cadencemessaging-infrastructure
◆Current state
Synapse, the Matrix homeserver from Element, shipped 1.164 and 1.165 within three weeks, each after release candidates, plus three 1.164 and two 1.163 patch releases. The captured entries only link to CHANGES.md, so the feed shows the cadence but not what changed for operators.
◆Where it's heading
The pattern is a predictable train: release candidates about a week before each stable minor, and quick patches on the current and previous branch. Without the changelog text in the feed, it is unclear whether these releases carry new features or mostly fixes and maintenance.
◆Prediction
A 1.166.0rc1 is likely within about two weeks, following the same rc-then-stable pattern; its content can't be predicted from these entries.

    Synapse 1.164 reaches stable after three RCs

    1.164.0 lands after three release candidates over a week, a longer rc cycle than 1.165 got. The feed links CHANGES.md without the details, so the contents of this minor aren't visible here.

    Third release candidate for 1.164, published the same hour as the 1.163.2 patch, which suggests a fix applied to both branches.
