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 JuiceFS?

JuiceFS is spending its v1.4 cycle on metadata-engine efficiency, one transaction at a time.

The v1.4 cycle is running in the open across three pre-releases — beta1 in May with 373 commits since v1.3, beta2 two weeks later, and rc1 in June. The recurring subject is the metadata layer: quota keys no longer create mass tombstones, quota lookups are batched to save a round trip, transactional key-value lookups collapse into a single transaction, and chunks commit in write order. Feature additions are narrow — custom tags in tier configuration, an upload-part stream API, and checkpoint support for multipart uploads in sync.

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.

JuiceFS is spending its v1.4 cycle on metadata-engine efficiency, one transaction at a time.

◆ Current state

The v1.4 cycle is running in the open across three pre-releases — beta1 in May with 373 commits since v1.3, beta2 two weeks later, and rc1 in June. The recurring subject is the metadata layer: quota keys no longer create mass tombstones, quota lookups are batched to save a round trip, transactional key-value lookups collapse into a single transaction, and chunks commit in write order. Feature additions are narrow — custom tags in tier configuration, an upload-part stream API, and checkpoint support for multipart uploads in sync.

◆ Where it's heading

This is a release cycle about cost at scale rather than new capability. Every metadata change removes a round trip, a tombstone, or a transaction from paths that run constantly, which is where a filesystem backed by object storage and an external metadata engine actually gets expensive. The sync and upload work points the same direction: multipart and streaming paths make large-object transfers resumable instead of restarting them. Contributor counts stay high across releases, so the pace is sustained rather than a push by one maintainer.

◆ Prediction

With rc1 cut and the changes since beta2 already down to 50 commits, a v1.4.0 final is the likely next step rather than further feature work.
