What is GitBook?

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.

What is rgm?

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

GitBook is quietly building an in-editor docs agent and hardening reusable-content workflows.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

◆ Current state

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

◆ Where it's heading

Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.

◆ Prediction

The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
