What is Stalwart?
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.
What is Twist?
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
6.3COMMS
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Twist
0.0COMMS
A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
