geopandas vs silx: at a glance
What is geopandas?
GeoPandas bet everything on shapely 2 and Pyogrio, and is now paying down pandas 3
The library is in patch mode on the 1.1 line, split between pandas 3.0 compatibility work - Copy-on-Write, the new string dtype - and a run of bug fixes that includes two separate SQL-injection hardenings in to_postgis. The visible history reaches back to the 1.0 pre-releases, where GeoPandas dropped shapely<2 and PyGEOS entirely and switched its default I/O engine from Fiona to Pyogrio.
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.

GeoPandas bet everything on shapely 2 and Pyogrio, and is now paying down pandas 3
◆ Current state
The library is in patch mode on the 1.1 line, split between pandas 3.0 compatibility work - Copy-on-Write, the new string dtype - and a run of bug fixes that includes two separate SQL-injection hardenings in to_postgis. The visible history reaches back to the 1.0 pre-releases, where GeoPandas dropped shapely<2 and PyGEOS entirely and switched its default I/O engine from Fiona to Pyogrio.
◆ Where it's heading
The 1.0 cycle collapsed a pile of optional backends into one geometry engine and one I/O engine, and the releases since have been about surviving what moves underneath: pandas 3.0 changing copy semantics and string storage. Expect the compatibility burden, not new spatial capability, to set the release cadence for now.
◆ Prediction
Further 1.1.x patches tracking pandas 3.x behaviour changes are the most likely next move, with the repeated to_postgis fixes suggesting more scrutiny of SQL construction there. Nothing in these entries points to a 1.2 feature line.

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.
