Synapse vs Misskey: at a glance
What is Synapse?
Synapse keeps a fixed release train: one minor a fortnight, patches in between.
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.
What is Misskey?
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
Synapse vs Misskey: editorial side-by-side
Synapse
5.0COMMS
Synapse keeps a fixed release train: one minor a fortnight, patches in between.
◆ 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.
Misskey
5.0COMMS
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
◆ Current state
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
◆ Where it's heading
Misskey's last two cycles are about making servers cheaper and safer to run: tighter Sentry data-collection defaults in 2026.10, lower memory and newer Node versions in 2026.11. Each one carries a breaking requirement that admins must check before upgrading.
◆ Prediction
Expect 2026.11.x patch releases for upgrade problems, especially around custom NODE_OPTIONS and systemd units. The entries do not show what the next feature cycle will target.
