Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
A side-by-side editorial comparison of Salon Booking System and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
Small patches every few weeks, and a salon console that keeps moving to mobile.
Salon Booking System is a WordPress appointment plugin releasing patch versions every few weeks, each a short list of fixes with one or two additions. The 10.30 line carries the substance: a mobile web app interface in March, drag-to-resize booking duration and WhatsApp quick-links in February, two-way Google Calendar sync improvements in April, and a forecasted-bookings screen with in-form service search in June. July's release is purely corrective — Revenue Guard report endpoints returning HTTP 500, and an empty time-slot grid on the booking form.
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

Two directions run through the patch stream. One is the salon owner's console moving to mobile, with a progressive web app calendar that supports drag-resize, walk-in badges and its own diagnostics. The other is closing revenue leaks: no-show handling, Revenue Guard reporting, a Stripe payment status refresh, discount exclusion rules. Security patches appear inside several of these releases with no announcement of their own, which matters to anyone tracking WordPress plugin risk.
Revenue Guard now has its own reporting endpoints and needed a fix within weeks of appearing, so it is under active development and likely to grow past reporting cards. The changelog format offers no roadmap beyond that.
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases.

Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.
WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
