What is FoReco?

Forecast reconciliation with a real object model, five years after it started returning bare matrices.

FoReco reconciles hierarchical forecasts across cross-sectional, temporal, and cross-temporal frameworks, and now covers both point and probabilistic reconciliation. The 1.3.0 release gave every reconciliation function a shared foreco S3 class carrying framework, function, forecast type, and reconciliation metadata, which replaced the loose attribute-and-helper pattern the package had used since 1.0.0. The follow-up 1.3.1 turned the same attention on the API's edges: strict argument validation with errors that name the expected and supplied values, and a help index pruned down to user-facing functions only.

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.

Forecast reconciliation with a real object model, five years after it started returning bare matrices.

◆ Current state

FoReco reconciles hierarchical forecasts across cross-sectional, temporal, and cross-temporal frameworks, and now covers both point and probabilistic reconciliation. The 1.3.0 release gave every reconciliation function a shared foreco S3 class carrying framework, function, forecast type, and reconciliation metadata, which replaced the loose attribute-and-helper pattern the package had used since 1.0.0. The follow-up 1.3.1 turned the same attention on the API's edges: strict argument validation with errors that name the expected and supplied values, and a help index pruned down to user-facing functions only.

◆ Where it's heading

The package is completing a reversal it started in 1.0.0. That release simplified outputs to plain matrices and pushed metadata into attributes reachable via recoinfo(); 1.3.0 removed recoinfo() outright and put the structure back as a class with components(), summary(), and plot() methods. The direction is toward being infrastructure rather than a function library — the class is exported through new_foreco_class() and a sibling package has already adopted it. Method coverage has meanwhile broadened from optimal combination into non-negative algorithms, bounded reconciliation, and Gaussian and sample-based probabilistic variants.

◆ Prediction

The soft-deprecated res2matrix() is flagged for removal, so a subsequent release should finish that cleanup; with the class now exported, expect more methods to hang off foreco objects rather than more top-level functions.

5.0

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.
