Stalwart vs Wire: at a glance
What is Stalwart?
SCIM v2 lands in the Enterprise tier, opening a provisioning surface beside the protocol work.
Stalwart ships weekly, and 0.16.20 breaks a long run of pure spec-completeness work by adding SCIM v2 to the Enterprise tier: core schema (RFC 7643), protocol (RFC 7644), cursor-based pagination (RFC 9865), the SCIM interoperability profile and the IPSIE lifecycle profile. The rest of the release is the established mix - conference links in calendar invites and alarms, 25 interface translations, and a fix run covering DANE lookup and failure semantics, Redis Sentinel deployments where rediss:// URLs connected to the master in cleartext, and cluster node leases that left removed nodes marked stale indefinitely.
What is Wire?
Calling is the one surface Wire's web client touches in every documented release.
Wire's web app ships production tags every one to three weeks. Four of the last six carry real upstream release notes and two are bare tags with no GitHub release behind them at all; a third reached our feed looking bare only because Wire published the notes upstream three days after cutting the tag. The documented work concentrates on calling - audio processing, background effects, session recovery - with Files and Shared Drives as the secondary thread.

Stalwart
6.3COMMS
SCIM v2 lands in the Enterprise tier, opening a provisioning surface beside the protocol work.
◆ Current state
Stalwart ships weekly, and 0.16.20 breaks a long run of pure spec-completeness work by adding SCIM v2 to the Enterprise tier: core schema (RFC 7643), protocol (RFC 7644), cursor-based pagination (RFC 9865), the SCIM interoperability profile and the IPSIE lifecycle profile. The rest of the release is the established mix - conference links in calendar invites and alarms, 25 interface translations, and a fix run covering DANE lookup and failure semantics, Redis Sentinel deployments where rediss:// URLs connected to the master in cleartext, and cluster node leases that left removed nodes marked stale indefinitely.
◆ Where it's heading
The protocol gap-closing continues, with DANE, iMIP, CalDAV and JMAP absorbing corrections every release, but SCIM points at a different axis: who is expected to deploy this. Provisioning, per-tenant branding, cluster lease handling and the recovery-admin impersonation fixes are operator concerns rather than mail-standard concerns, and they have been accumulating since 0.16.15. Calendar remains the least settled surface, now extending into localization rather than correctness alone.
◆ Prediction
SCIM shipped with the interoperability and IPSIE profiles attached, so the near-term work is likely the directory-side corrections that follow first contact with real identity providers - the same pattern the LDAP and SQL directory integrations have been producing. The 25 new translations open a localization surface that has not yet had to survive a release cycle.
Wire
5.0COMMS
Calling is the one surface Wire's web client touches in every documented release.
◆ Current state
Wire's web app ships production tags every one to three weeks. Four of the last six carry real upstream release notes and two are bare tags with no GitHub release behind them at all; a third reached our feed looking bare only because Wire published the notes upstream three days after cutting the tag. The documented work concentrates on calling - audio processing, background effects, session recovery - with Files and Shared Drives as the secondary thread.
◆ Where it's heading
Two threads run through the releases that document themselves. Calling is being hardened rather than widened: enhanced audio processing and WebSocket recovery were flipped on by default in early July, background effects were then chased for performance under system load through late July, and in the August release they land inside calls proper. The second thread is file collaboration, where Shared Drives gained filtering and sorting in late July. August adds a narrower third: a user-facing recovery path for Proteus decryption failures, which is encryption plumbing surfacing as something a person can act on.
◆ Prediction
The next documented release most likely continues on calling reliability or extends the background-effects work. Nothing in these entries points to a new surface opening.
