OpenDataDiscovery vs silx: at a glance
What is OpenDataDiscovery?
Four ODD Platform releases in two weeks, and not one of them changes the product
ODD Platform's recent releases are entirely dependency and build hygiene. Four tags went out between 20 March and 3 April 2026: a Spring Boot security upgrade, a container Java runtime bump from 17.0.2 to 17.0.18, an alignment pass across apache-lang, okhttp and nimbus-jose-jwt, a commit whose stated purpose was forcing a build, and a netty-bom downgrade to unbreak UI static assets. Two contributors account for all of it, and no entry describes a user-facing change.
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.

Four ODD Platform releases in two weeks, and not one of them changes the product
◆ Current state
ODD Platform's recent releases are entirely dependency and build hygiene. Four tags went out between 20 March and 3 April 2026: a Spring Boot security upgrade, a container Java runtime bump from 17.0.2 to 17.0.18, an alignment pass across apache-lang, okhttp and nimbus-jose-jwt, a commit whose stated purpose was forcing a build, and a netty-bom downgrade to unbreak UI static assets. Two contributors account for all of it, and no entry describes a user-facing change.
◆ Where it's heading
The pattern is a project being kept patched rather than developed — the visible work is closing dependency vulnerabilities and repairing the fallout when those upgrades break something. The netty downgrade is the clearest illustration: an upgrade broke static asset serving and the fix was to step back a patch version. Nothing in these entries touches data discovery, cataloguing or lineage, which is what the platform actually does.
◆ Prediction
Nothing here indicates planned feature work; on this evidence the next releases are most likely more dependency alignment, since the netty and Spring Boot upgrades in this window are the kind that arrive on a security-advisory schedule rather than a product one.

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.
