A side-by-side editorial comparison of Easy!Appointments and Mattermost — release velocity, themes, recent moves, and the top alternatives to consider.
Easy!Appointments makes CalDAV sync failures explain themselves.
Easy!Appointments ships slowly through alpha and beta pre-releases. The 1.6.0 cycle added Jitsi meeting links for appointments booked on the public page, a meeting-link field, and a dedicated Google Calendar integration section. The 1.6.1 pre-releases tighten input validation and make CalDAV sync usable on local networks, with failures explained on the calendar page.
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
Easy!Appointments ships slowly through alpha and beta pre-releases.

The 1.6.1 pre-releases tighten input validation and make CalDAV sync usable on local networks, with failures explained on the calendar page.
The scheduler is building out integrations (Google Calendar, CalDAV, Jitsi) and then hardening them so self-hosters can diagnose problems without reading logs. Cadence is slow, with months between pre-releases, and the 1.6.0 notes are repeated across three cuts.
A 1.6.1 stable release with the CalDAV and validation work is the likely next step; the entries don't show new integrations queued behind it.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
