A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.
This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.
The trajectory in the captured window points to operational maintenance rather than category expansion: tightening data validation, fixing edge cases in audit reporting, supporting more telecom-data formats. The earlier Bouygues API connector hinted at a machine-to-machine ambition with the major French carriers, but follow-through (Orange, SFR) is not visible in this window. Public release cadence appears to have gone quiet.
Hard to call from the visible entries. If the Orange and SFR API connectors promised in 2024 ever shipped, they would have been the natural next chapter; their absence suggests either delayed delivery or a move to private release notes. Watch for whether public changelog cadence resumes at all.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
The work points toward production maturity: closing JMAP spec gaps, adding high-availability primitives (Redis Sentinel coordination), and tightening TLS, DANE, and encryption. Stalwart is positioning itself as a standards-faithful, deployable alternative to legacy mail stacks rather than chasing new user-facing features.
Expect continued point releases that finish protocol conformance and expand operational features—high-availability backends, certificate handling, and encryption options—rather than a major feature pivot.
