What is Lightdash?

Lightdash keeps handing authoring to outside agents and keeping the governed layer for itself.

Lightdash has spent two months rebuilding around agents rather than around its own web editor. Data apps are scaffolded and iterated locally with Cursor, Claude Code or Codex and uploaded for the instance to build; Deep Research runs multi-step investigations against the warehouse; content as code now covers charts, dashboards, spaces, permissions, virtual views, AI agents, automations, users, groups and roles. The conventional BI surface is still maintained — SQL Runner big numbers, filter groups, timezone handling — but it is no longer where new capability lands. The newest release is a CLI slug rename that keeps Lightdash and the local files in step.

What is OpenMC?

OpenMC's random ray solver has gone from new arrival to the centre of every release

OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.

Lightdash keeps handing authoring to outside agents and keeping the governed layer for itself.

◆ Current state

Lightdash has spent two months rebuilding around agents rather than around its own web editor. Data apps are scaffolded and iterated locally with Cursor, Claude Code or Codex and uploaded for the instance to build; Deep Research runs multi-step investigations against the warehouse; content as code now covers charts, dashboards, spaces, permissions, virtual views, AI agents, automations, users, groups and roles. The conventional BI surface is still maintained — SQL Runner big numbers, filter groups, timezone handling — but it is no longer where new capability lands. The newest release is a CLI slug rename that keeps Lightdash and the local files in step.

◆ Where it's heading

The split is deliberate: authoring and interrogation move outward to whatever agent the user already runs, while the governed metrics, permissions and build stay inside Lightdash. The slug-rename command is a small marker of how far that has gone — refactoring tools are now needed for the repository rather than for the web UI, because that is where the content lives. Deep Research extends the same bet from generating artifacts to conducting analysis, testing competing explanations and validating numbers instead of emitting a chart.

◆ Prediction

Expect more repository-side maintenance commands of the slug-rename kind — moves, deletes, bulk edits across content-as-code files — since the agent workflow now produces content faster than the CLI can tidy it.

OpenMC's random ray solver has gone from new arrival to the centre of every release

◆ Current state

OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.

◆ Where it's heading

The project is layering a deterministic-adjacent solver alongside its Monte Carlo core rather than replacing it, and the ratio of random-ray work to core-solver work in each release keeps rising. In parallel it is packaging expert workflows into objects — R2SManager is the clearest case, turning a multi-stage shutdown dose calculation into a class rather than a recipe. The Python API is where most of that packaging surfaces, and it is also where the compatibility breaks land, with the minimum version moving to 3.12 in 0.16.0.

◆ Prediction

Given that every release since 0.15.0 has expanded the random ray solver's feedback and tally coverage, the next is likely to continue closing the gap between it and the main solver's feature set. The notes do not indicate whether it is intended to become a default path.
