Delta Chat vs Misskey: at a glance
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 moves to Sentry v11 and keeps shipping security fixes in its monthly releases.
Misskey, the ActivityPub social server, shipped 2026.10.0 with a security fix and an HTTP Signatures fix, then 2026.10.1, which moves to Sentry SDK v11 and replaces sendDefaultPii with a dataCollection setting. The 2026.10.2 alpha improves how quote posts from Mastodon and other software display and makes the server stop safely on a bad job-queue config.

Delta Chat
5.0COMMS
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.
Misskey
5.0COMMS
Misskey moves to Sentry v11 and keeps shipping security fixes in its monthly releases.
◆ Current state
Misskey, the ActivityPub social server, shipped 2026.10.0 with a security fix and an HTTP Signatures fix, then 2026.10.1, which moves to Sentry SDK v11 and replaces sendDefaultPii with a dataCollection setting. The 2026.10.2 alpha improves how quote posts from Mastodon and other software display and makes the server stop safely on a bad job-queue config.
◆ Where it's heading
Each version goes through alpha and beta tags before stable, and security fixes appear in most stable releases since 2026.9.0. Federation polish, such as how other servers' quotes and signatures are handled, is the main user-facing thread.
◆ Prediction
Expect 2026.10.2 stable soon after its alpha, carrying the quote display and deck fixes, with 2026.11 alphas following on the monthly cadence.
