Description

Underworld3 v3.0.1

Patch release with build reliability fixes and documentation improvements.

Bug Fixes

  • Fix Dockerfile resilience to dependency version differences
  • Fix binder launcher dispatch payload and YAML quoting

Improvements

  • Auto-detect binder launcher ref from git tag in RTD documentation
  • Add manual dispatch overrides for binder image builds
