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 Apache SkyWalking?

SkyWalking is rebuilding its own foundations — its own database, its own runtime, and now GenAI traces

Apache SkyWalking ships roughly one major a year. 10.4.0 added GenAI observability, replaced the Groovy-dependent runtime with a new OAL V2 engine, and became compatible with Grafana Tempo. Before it, 10.3.0 landed a new trace model in BanyanDB, and 10.2.0 removed the H2 storage option permanently while deepening BanyanDB support.

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.

SkyWalking is rebuilding its own foundations — its own database, its own runtime, and now GenAI traces

◆ Current state

Apache SkyWalking ships roughly one major a year. 10.4.0 added GenAI observability, replaced the Groovy-dependent runtime with a new OAL V2 engine, and became compatible with Grafana Tempo. Before it, 10.3.0 landed a new trace model in BanyanDB, and 10.2.0 removed the H2 storage option permanently while deepening BanyanDB support.

◆ Where it's heading

Two rewrites are running at once. Storage is consolidating onto BanyanDB, SkyWalking's purpose-built database, with alternatives being removed rather than deprecated. The query and aggregation layer is moving off Groovy onto a typed, immutable OAL V2 engine with real error locations. GenAI observability arriving on top of that suggests the foundations work was clearing room for new telemetry types.

◆ Prediction

Expect the next major to extend GenAI observability and continue narrowing supported storage backends toward BanyanDB, with further OAL V2 migration on the way.
