What is roclang?

A roxygen2 documentation-reuse helper whose release notes are mostly upstream damage control.

roclang lets package authors pull documentation text out of an existing function's roxygen block and splice it into their own — extract_roc_text() with type = "param", "dot_params" or a section selector. The feature surface has been stable since 0.2.1; the parameter-matching rules and the checks for invalid or ambiguous extractions are the substance of what shipped.

What is silx?

silx settles into maintenance a release after its PySide6 migration

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

0.0

A roxygen2 documentation-reuse helper whose release notes are mostly upstream damage control.

◆ Current state

roclang lets package authors pull documentation text out of an existing function's roxygen block and splice it into their own — extract_roc_text() with type = "param", "dot_params" or a section selector. The feature surface has been stable since 0.2.1; the parameter-matching rules and the checks for invalid or ambiguous extractions are the substance of what shipped.

◆ Where it's heading

Nearly every release since 0.2.0 has been reactive. The package parses documentation text produced by other packages, so a wording change in stats::lm()'s documentation breaks its test suite, and a roxygen2 selection-semantics change forces its parameter matching to follow. The 0.2.3 release is exactly this pattern again. Release cadence has slowed to roughly one entry every two years, and the last two carried no functional change at all.

◆ Prediction

Further releases are most likely triggered by upstream roxygen2 or base R documentation edits breaking tests rather than by new extraction capability. The entries show no queued feature work.

silx settles into maintenance a release after its PySide6 migration

◆ Current state

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

◆ Where it's heading

The cadence has slowed markedly since April, and the content has shifted from structural change to plotting and colormap refinement. That is the expected shape after a binding migration: downstream beamline code needs a stable target, so the project trades feature velocity for a quiet surface. The gap between 3.0.1 in May and 3.1.0 in August is the clearest signal of the deliberate slowdown.

◆ Prediction

Expect further point releases servicing the plotting and fitting widgets rather than another structural change, with feature work continuing to arrive in the 3.1.x minors rather than patches.
