What is Delta Chat?

Delta Chat is quietly replacing its email identity with relays

Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.

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.

Delta Chat vs Misskey: editorial side-by-side

D5.0

Delta Chat is quietly replacing its email identity with relays

◆ Current state

Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.

◆ Where it's heading

The project is removing email from what users see and from how they think about identity, with relays taking its place as multi-path infrastructure. Fetching from every relay and sending through the fastest one treats a relay as replaceable, which matters for a federated messenger. Around that, the client keeps closing feature gaps with mainstream messengers through pinning, channel reactions and better group notification handling.

◆ Prediction

Expect further relay management work, as the core notes show this is where the structural change is. Channels are the next most active surface, with reaction privacy already changing there.

5.0

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.
