What is Botpress?
Botpress spent its last visible releases on the agent authoring seat — then went quiet in April.
Three releases account for all six entries; every one appears twice, once from the marketing changelog and once from the docs mirror. The Autonomous Node got a real prompt editor with a macro menu for referencing knowledge bases and variables plus a raw Markdown mode; Studio multiplayer was rebuilt for latency; the integrations Hub was redesigned; Knowledge Bases gained Linear, GitHub, Confluence, Google Drive and Notion as sources; and Studio picked up model selection for the Vision Agent and a --url flag on CLI deploys. The newest entry is from mid-April.
What is Stalwart?
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

Botpress
0.0COMMS
Botpress spent its last visible releases on the agent authoring seat — then went quiet in April.
◆ Current state
Three releases account for all six entries; every one appears twice, once from the marketing changelog and once from the docs mirror. The Autonomous Node got a real prompt editor with a macro menu for referencing knowledge bases and variables plus a raw Markdown mode; Studio multiplayer was rebuilt for latency; the integrations Hub was redesigned; Knowledge Bases gained Linear, GitHub, Confluence, Google Drive and Notion as sources; and Studio picked up model selection for the Vision Agent and a --url flag on CLI deploys. The newest entry is from mid-April.
◆ Where it's heading
The work concentrates on two things: making the agent's prompt directly editable and inspectable rather than buried in UI, and widening the set of systems an agent can be grounded in. Both are builder-facing rather than end-user-facing, which fits a platform competing on how fast a team can get an agent into production. What comes after April is not visible in this feed.
◆ Prediction
On the visible pattern the next moves are more knowledge-source connectors and further Studio editor work; the three-month gap since the last entry makes anything beyond that unsupported.
Stalwart
5.0COMMS
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
◆ Current state
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.
◆ Where it's heading
The project is building toward being the reference implementation of the modern mail stack — JMAP first, with the classic protocols held at parity rather than left behind. The fix lists have shifted in character over these eight releases: less "feature does not work", more "spec detail is wrong", which is what a codebase looks like as it converges on conformance. Security and multi-tenancy fixes keep appearing alongside the protocol work, indicating real deployments are exercising the newer subsystems.
◆ Prediction
The next releases most likely track revisions to the drafts already implemented — DKIM2, JMAP push and the calendar drafts are all still moving — rather than adding another protocol surface. Expect continued JMAP conformance fixes until the test suite stops producing them.
