About Synapse
Synapse publishes only a changelog link, so its feed records releases without describing them
Synapse is the reference Matrix homeserver, and every entry captured here has the same 80-character body: a link to CHANGES.md on the release branch. Release candidates and finals alternate on a regular rhythm — 1.158, 1.159, and now a second candidate for 1.160 — but no note in this feed says what any of them contain. Judging any individual release from this source is impossible by construction.
