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 Stape?
Stape is layering profitability and policy guardrails onto its server-side tracking core.
Stape is shipping monthly across two threads: tooling around its server-side GTM containers and editorial guidance for advertisers navigating platform policy shifts. April brought POAS (profit on ad spend) data feed, GTM Helper updates for restricted environments, and a Smart Pause billing mechanism. February-March added AI-summarized tracking checks, log/monitoring overhauls, and reactive guidance on Meta's health-data limits and Google Ads' Customer Match changes.

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.
Stape
2.5ANALYTICS
Stape is layering profitability and policy guardrails onto its server-side tracking core.
◆ Current state
Stape is shipping monthly across two threads: tooling around its server-side GTM containers and editorial guidance for advertisers navigating platform policy shifts. April brought POAS (profit on ad spend) data feed, GTM Helper updates for restricted environments, and a Smart Pause billing mechanism. February-March added AI-summarized tracking checks, log/monitoring overhauls, and reactive guidance on Meta's health-data limits and Google Ads' Customer Match changes.
◆ Where it's heading
The product is moving up the stack from raw server-side tag plumbing into outcome-oriented features (profit data, recommended actions, tracking health). The frequent advertising-policy posts position Stape as a tracking-policy interpreter as much as an infrastructure provider. Expect more proprietary data products like POAS and tighter cross-platform compliance tooling as third-party signals keep degrading.
◆ Prediction
The next directional move likely productizes more advertiser-side metrics (LTV feeds, attribution overlays) on top of sGTM, plus expanded automation around platform compliance changes. Smart Pause economics suggest stricter tier enforcement is coming.
