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 Jaeger?

Jaeger folds its MCP server into the query service and drops Elasticsearch 6

Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.

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.

Jaeger folds its MCP server into the query service and drops Elasticsearch 6

◆ Current state

Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.

◆ Where it's heading

Jaeger is treating machine consumption of traces as a first-class query path rather than an add-on. Merging jaegermcp into jaegerquery means the MCP surface ships wherever query ships, and trace summaries give both the UI and any agent a cheap way to scan results before pulling full traces. On storage, the direction is fewer supported backends maintained better, with ClickHouse steadily gaining parity.

◆ Prediction

Expect the trace-summaries path to become the default for search across storage backends, and further ClickHouse feature work as the Elasticsearch surface is trimmed rather than extended.
