poppr vs silx
A side-by-side editorial comparison of poppr and silx — release velocity, themes, recent moves, and the top alternatives to consider.
poppr vs silx: at a glance
What is poppr?
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
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 population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
◆ Current state
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
◆ Where it's heading
This is a mature package being kept installable rather than developed. The deprecation promised in 2.9.0 — removing blacklist in 2.10 — has not arrived across three years and four releases, which is the clearest sign that no feature line is currently active. What movement exists comes from outside contributors and from the toolchain moving underneath the package.
◆ Prediction
The next release is most likely another CRAN or compiler-compatibility fix; the promised 2.10 removal of blacklist would be the first sign of active development resuming, but nothing in these entries indicates it is being prepared.

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.
