GitBook is quietly building an in-editor docs agent and hardening reusable-content workflows.
GitBook ships weekly, and two threads dominate: the GitBook Agent (its in-editor AI) and reusable/change-request tooling. Recent releases let the Agent hold multiple chats per change request, read and set variables across docs, and handle more complex multi-step edits, while change requests gained diffs for reusable blocks and integration blocks inside reusable content. An API to update change-request content rounds out a docs-as-code posture.
Expo is running its SDK and EAS release engine at a fast, steady clip.
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.

An API to update change-request content rounds out a docs-as-code posture.
The direction is an authoring surface where an AI agent does structural work — updating variables everywhere, executing multi-step edits — inside a reviewable change-request flow, and where content can be automated via API from CI/CD. GitBook is positioning itself less as a docs editor and more as a governed, agent-assisted documentation pipeline.
Expect continued GitBook Agent capability expansion (broader edit actions, deeper structural understanding) and more API coverage for change requests to support automated, pipeline-driven documentation updates.

Two threads: keeping the SDK on a rapid major-version cadence, and deepening EAS as the paid cloud around it (workflows, device registration, testing insights). The MCP server going free signals interest in making Expo projects addressable by AI coding assistants. Expect the SDK cadence to hold and EAS to keep adding CI and testing surface.
Next likely: point releases and migration guidance following SDK 57, and continued EAS Workflows and testing features. Specific features are hard to call from the stub-level content in this feed.
