What is Rocket.Chat?

Rocket.Chat's 8.6 RC line adds self-hostable translation and a unified presence engine

This feed tracks Rocket.Chat GitHub release-candidate tags, and the top of the window is dominated by empty 8.6.0-rc.x and 8.5.0-rc.x 'Bump meteor version' cuts with the real content concentrated in the 8.6.0-rc.0 minor release. Note: this appears to be a duplicate product row of the other Rocket.Chat entry in the catalog (same RocketChat/Rocket.Chat repo, same releases, different slug/UUID); it is being classified independently off its own entries. Because these are RCs, capabilities are staged into a pre-release train rather than GA.

What is Capacities?

Capacities is becoming an AI-connected knowledge hub with a real developer API.

Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.

Rocket.Chat's 8.6 RC line adds self-hostable translation and a unified presence engine

◆ Current state

This feed tracks Rocket.Chat GitHub release-candidate tags, and the top of the window is dominated by empty 8.6.0-rc.x and 8.5.0-rc.x 'Bump meteor version' cuts with the real content concentrated in the 8.6.0-rc.0 minor release. Note: this appears to be a duplicate product row of the other Rocket.Chat entry in the catalog (same RocketChat/Rocket.Chat repo, same releases, different slug/UUID); it is being classified independently off its own entries. Because these are RCs, capabilities are staged into a pre-release train rather than GA.

◆ Where it's heading

The 8.6 cycle leans into self-hosted and privacy-controlled deployments: LibreTranslate for fully on-premise message auto-translation, Virtru as an external ABAC attribute store, and a unified presence engine with priority-based claims. In parallel there is a broad, deliberate migration of legacy DDP methods to REST endpoints (settings, spotlight, im.blockUser, e2e key requests, rooms.join), signaling an API-surface modernization ahead of a 9.0.0 removal.

◆ Prediction

The rc.x cadence points to an 8.6.0 GA cut once the release candidates settle. Expect the DDP-to-REST migration to continue toward the flagged 9.0.0 removal.

C6.3

Capacities is becoming an AI-connected knowledge hub with a real developer API.

◆ Current state

Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.

◆ Where it's heading

The arc is Capacities moving from a closed personal tool toward a platform: API 2.0 gives developers programmatic access, while the AI Chat Connectors let external assistants read and increasingly write into a user's space. Its AI work emphasizes user control — local-first search, choose-your-model — rather than a single hosted assistant. Cadence is high and consistent.

◆ Prediction

With the API opened and connectors moving from read to write, the likely next step is a richer integration surface — third-party tools and agents building on the API — plus more of what connected AI apps can create inside a space.
