What is Discourse?

Monthly releases on time, security out-of-band, and the changelog living somewhere else

Discourse ships a dated minor every month — 2026.4 through 2026.7 in this window — and back-patches several supported branches alongside each one. Critical security fixes travel separately as out-of-band intermediate releases, the most recent on July 31 covering the 2026.8 pre-release line plus the 2026.7, 2026.6 and 2026.1 branches. The release topics carry no detail of their own; each links out to releases.discourse.org. The remainder of the feed is administrator documentation.

What is Plain?

Sidekick got skills and MCP; now Plain is clearing the path to move your history in.

Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.

Monthly releases on time, security out-of-band, and the changelog living somewhere else

◆ Current state

Discourse ships a dated minor every month — 2026.4 through 2026.7 in this window — and back-patches several supported branches alongside each one. Critical security fixes travel separately as out-of-band intermediate releases, the most recent on July 31 covering the 2026.8 pre-release line plus the 2026.7, 2026.6 and 2026.1 branches. The release topics carry no detail of their own; each links out to releases.discourse.org. The remainder of the feed is administrator documentation.

◆ Where it's heading

The cadence is the signal and it has not wavered: a monthly minor, patches reaching back to branches cut in January, and security decoupled from the feature train. That is the maintenance posture of self-hosted software whose installs upgrade on their own schedule, and the branch count is the tell — still patching 2026.1 at the end of July means an install that has sat still for six months is covered. Where the product is actually heading surfaces in the documentation instead, where the AI bot's support for external MCP servers is the only entry in the last ten describing a capability rather than a version number.

◆ Prediction

The August 2026 monthly release is the near-certain next entry, in the same pointer-topic shape. What lands inside it cannot be read from this feed — these topics are links, so any call on direction would have to come from the linked changelog.

Sidekick got skills and MCP; now Plain is clearing the path to move your history in.

◆ Current state

Plain's recent releases built Sidekick from an in-thread helper into an operator that uses workspace skills and connects to any MCP server, with workflows becoming the trigger layer for that agent work. The newest entry moves to the other end of the funnel: custom importers pull past conversations in from any tool, including in-house systems, with no built-in importer required.

◆ Where it's heading

Capability, then autonomy, then extensibility, and now onboarding. Removing the importer dependency means adoption stops being capped by Plain's connector roadmap, the same way the agent's ceiling stopped being its integration roadmap. The pattern across both is Plain declining to sit as the bottleneck between a customer's existing systems and its own product.

◆ Prediction

Expect the importer work to be followed by tooling that puts migrated history to use - Sidekick reading imported conversations for context is the obvious next step given the skills and MCP groundwork already shipped.
