Mailu vs Misskey: at a glance
What is Mailu?
Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
Mailu's 2024.06 branch ships pinned releases, each tied to a single issue. October brought resolver fixes for the DNSSEC KSK rollover and SERVFAIL healthchecks, Roundcube 1.6.20, then PHP2Shell CVE mitigations in webmail followed by the patched PHP runtime. 2024.06.68 on 8 November carries the same PHP2Shell mitigation note again.
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.

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
◆ Current state
Mailu's 2024.06 branch ships pinned releases, each tied to a single issue. October brought resolver fixes for the DNSSEC KSK rollover and SERVFAIL healthchecks, Roundcube 1.6.20, then PHP2Shell CVE mitigations in webmail followed by the patched PHP runtime. 2024.06.68 on 8 November carries the same PHP2Shell mitigation note again.
◆ Where it's heading
The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.
◆ Prediction
The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.

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.
