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 Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

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.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
