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 updown.io?
updown.io now checks that ports stay closed, not just that services stay up.
updown ships infrequently but substantively, maintained by a single developer. The past year added Pulse monitoring for inbound heartbeats, body string matching for those pulses, two probe-location changes, and a ten-year history chart on status pages. The newest release adds closed-port monitoring, so a check can assert that a TCP port is unreachable — firewall verification rather than an availability test.

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.
updown.io
2.5ANALYTICS
updown.io now checks that ports stay closed, not just that services stay up.
◆ Current state
updown ships infrequently but substantively, maintained by a single developer. The past year added Pulse monitoring for inbound heartbeats, body string matching for those pulses, two probe-location changes, and a ten-year history chart on status pages. The newest release adds closed-port monitoring, so a check can assert that a TCP port is unreachable — firewall verification rather than an availability test.
◆ Where it's heading
The arc is widening what a single check can assert rather than expanding elsewhere in the product. Pulse brought inbound heartbeats alongside outbound polling, string matching let a pulse fail on its content instead of only its absence, and closed-port checks invert the assertion entirely. Probe-network work runs in parallel — Toronto replaced the retired Montreal node for IPv6, Cape Town came online in 2025 — and every release carries a tail of small fixes rather than a second headline feature.
◆ Prediction
The next release most likely extends conditions on the existing check types again rather than introducing a new monitoring modality, given that each of the last three headline features reused the same probe machinery. The recurring maintenance tail points to continued consolidation around alerting, recipients, and API access.
