What is Lightdash?
Lightdash is handing the analyst's job to agents and keeping the semantic layer as referee.
Lightdash has spent the last two months rebuilding around agents rather than around its own web editor. Data apps can be scaffolded and iterated locally with Cursor, Claude Code or Codex and uploaded for the instance to build; chart types can be generated from a prompt; verified content and AI agent answers now share one store that the Lightdash MCP serves to outside tools. The conventional BI surface is still being maintained — SQL Runner big numbers, filter groups, timezone handling — but it is no longer where the new capability lands.
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.

Lightdash is handing the analyst's job to agents and keeping the semantic layer as referee.
◆ Current state
Lightdash has spent the last two months rebuilding around agents rather than around its own web editor. Data apps can be scaffolded and iterated locally with Cursor, Claude Code or Codex and uploaded for the instance to build; chart types can be generated from a prompt; verified content and AI agent answers now share one store that the Lightdash MCP serves to outside tools. The conventional BI surface is still being maintained — SQL Runner big numbers, filter groups, timezone handling — but it is no longer where the new capability lands.
◆ Where it's heading
The pattern is a deliberate split: authoring and interrogation move outward to whatever agent the user already runs, while the governed metrics, permissions and build stay inside Lightdash. Deep Research extends that from generating artifacts to conducting analysis — exploring data, testing competing explanations, validating numbers. Content as code now covers charts, dashboards, permissions, automations, users and roles, which makes the whole instance addressable by an agent through a repository rather than a UI.
◆ Prediction
Expect the next releases to make agents first-class operators of the instance itself — driving the content-as-code surface to refactor resources and access, and extending Deep Research from answering questions to monitoring for the anomalies it currently only explains.

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.
