What is hexfont?

A GNU Unifont packager whose real work is making a huge font load fast.

hexfont ships GNU Unifont's hex bitmap files to R as bittermelon font objects, covering the full Unicode range. The last two releases were about load cost and portability: a user-level cache for precompiled fonts, then making that cache read-only by default so nothing is written unless asked. The font data itself tracks Unifont v16.0.02.

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.

A GNU Unifont packager whose real work is making a huge font load fast.

◆ Current state

hexfont ships GNU Unifont's hex bitmap files to R as bittermelon font objects, covering the full Unicode range. The last two releases were about load cost and portability: a user-level cache for precompiled fonts, then making that cache read-only by default so nothing is written unless asked. The font data itself tracks Unifont v16.0.02.

◆ Where it's heading

Each release does two things — resync with a newer GNU Unifont and shave the cost of using it. The performance thread has been the more consequential one, moving from the ucp argument that restricts which code points get read, to a full precompiled cache. Version 1.0.0 also walked back the R 4.1 pipe to keep the package usable on R 4.0.

◆ Prediction

Future releases most likely follow GNU Unifont's own version cadence, with occasional cache or loading refinements.

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.
