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.

What is Zipkin?

Zipkin's last release was January 2025 — a dependency bump, and then nothing.

The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.

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.

Zipkin's last release was January 2025 — a dependency bump, and then nothing.

◆ Current state

The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.

◆ Where it's heading

This is a project in preservation rather than development. The pattern across the window — feature in May 2024, then three releases of purely defensive dependency work, then silence since January 2025 — describes a mature tracing server being kept safe to run rather than extended. The distributed-tracing work that would once have landed here now largely happens in OpenTelemetry, which Zipkin interoperates with rather than competes against.

◆ Prediction

The feed has produced nothing for nineteen months, so the honest read is that no next release is scheduled. If one comes, the shape of the last three says it will be another dependency and base-image refresh rather than new capability.
