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 OctoPrint?

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

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.

2.5

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

◆ Current state

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

◆ Where it's heading

Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.

◆ Prediction

Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
