Release Notes

openplan-labs/PythonPDDL (jupyddl)

v2.4.0

Compare Source

Added

• A Research view in the workbench. jupyddl.learn shipped in 2.3.0 with
  its results only in .docs/ and a video, which meant the published site said
  nothing about the biggest addition in the release. The view carries the
  measured run: imitation against hff and goalcount, the per-instance
  spread behind the mean, the logistics loss and why the feature space causes
  it, and the three claims that turned out to be wrong. Its numbers are built
  from promo/rl-data.json — the same cache the RL video renders from — so
  the page and the video cannot drift apart, and a test pins them together.

Fixed

• Reading the workbench no longer costs a 10 MB download. <main> was
  hidden until Pyodide reported ready, so every page of prose, the requirement
  matrix and the new Research view sat behind a full-screen spinner waiting for
  a runtime none of them use. The shell now renders immediately from the
  committed bundle, the boot notice is a status bar rather than a splash
  screen, and only the controls that actually run a planner stay disabled until
  the interpreter arrives.

Changed

• Python 3.10 is the new floor, and the matrix runs 3.10 through 3.14.
  3.9 reached end of life in October 2025; requires-python moved to match
  what is actually tested.
• The pddl-examples submodule advances to a corpus that now grows on its own:
  it imports fresh domains from planning.domains daily.
• All URLs follow the organisation's rename to openplan-labs.

Removed

• Mergify. Its auto-merge rule waited on an approving review that a
  single-maintainer project does not produce, and its reviewer-assign rule
  pinged an inactive account; every recent pull request was merged by hand.
