What is nipnTK?

nipnTK's toolkit is settled; the last two years have gone into packaging, not methods.

An R implementation of the NiPN anthropometric data-quality checks — age heaping, age ratio tests, digit preference and the rest. The methods have been stable since the first CRAN release in 2020; the substantive change since was fixing ageRatioTest() for missing and numeric age values, shipped as a GitHub development release in April 2024 and to CRAN the next day. The most recent release is explicitly routine upkeep: refactored functions, a test for age heaping, pkgdown moved to the nutriverse template, citation and funding metadata.

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.

nipnTK's toolkit is settled; the last two years have gone into packaging, not methods.

◆ Current state

An R implementation of the NiPN anthropometric data-quality checks — age heaping, age ratio tests, digit preference and the rest. The methods have been stable since the first CRAN release in 2020; the substantive change since was fixing ageRatioTest() for missing and numeric age values, shipped as a GitHub development release in April 2024 and to CRAN the next day. The most recent release is explicitly routine upkeep: refactored functions, a test for age heaping, pkgdown moved to the nutriverse template, citation and funding metadata.

◆ Where it's heading

This is a maintained reference implementation rather than an evolving product. Release notes are dominated by repository plumbing — CI workflows, website templates, badges, CITATION files — which is what a package looks like once its statistical surface is complete and the work shifts to keeping it installable and citable. The nutriverse pkgdown template and shared conventions place it inside a family of nutrition packages from the same maintainer rather than standing alone.

◆ Prediction

Expect continued maintenance releases driven by CRAN policy and the nutriverse template rather than new checks, since two of the last three releases contained no method changes at all.

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.
