Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Misskey and Shortwave — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.

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.
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.

Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.
