What is logr?

A SAS-style logging package for R, shipping small and slowly by design.

logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.

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.

2.5

A SAS-style logging package for R, shipping small and slowly by design.

◆ Current state

logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.

◆ Where it's heading

The arc runs from correctness work on warning and error capture toward giving users control over where log output goes and how it is formatted. Recent releases are refinements of message content rather than new logging concepts, which is what a package settling into maintenance looks like. Nothing in these entries suggests an expansion of scope beyond the SAS-log-emulation brief.

◆ Prediction

Expect continued low-volume maintenance releases refining message detail and integration with the rest of the r-sassy suite, rather than new logging capability.

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.
