What is DuckDB?

Six releases, all patches — this window shows DuckDB's maintenance machine, not its roadmap

Every entry in this window is a bugfix release, and two release lines are being maintained side by side: 1.5.5, 1.5.4, 1.5.3, 1.5.2 and 1.5.1 on the current branch, with 1.4.5 shipped the same day as 1.5.4 for users still on the older line. The content is backports, race-condition fixes, extension and build plumbing, and in 1.5.5 a backport of out-of-bounds security fixes. Feature releases sit outside this window, so what is visible is the patch cadence rather than the direction.

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.

Six releases, all patches — this window shows DuckDB's maintenance machine, not its roadmap

◆ Current state

Every entry in this window is a bugfix release, and two release lines are being maintained side by side: 1.5.5, 1.5.4, 1.5.3, 1.5.2 and 1.5.1 on the current branch, with 1.4.5 shipped the same day as 1.5.4 for users still on the older line. The content is backports, race-condition fixes, extension and build plumbing, and in 1.5.5 a backport of out-of-bounds security fixes. Feature releases sit outside this window, so what is visible is the patch cadence rather than the direction.

◆ Where it's heading

The pattern is a project treating its previous minor as a supported branch rather than abandoning it — same-day 1.4.5 and 1.5.4 releases, with fixes explicitly backported from the newer line. Patch spacing has tightened over the window, from roughly two months between 1.5.1 and 1.5.2 to about five weeks between 1.5.4 and 1.5.5. Each release also points at an announcement blog post, so the substantive narrative lives off the feed.

◆ Prediction

The visible entries only support a continuation of the same pattern: further patch releases on both the 1.5 and 1.4 lines, with fixes backported between them. Nothing in this window signals what the next feature release contains.

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.
