Unreleased

0.2.1 - 2025-12-20

Semi-incompatible changes

• Python implementation:

    • switch to versioned names for the facet unstable features so that, with the 0.32.x addition, the features are now named facet030-unstable and facet032-unstable
    • switch to a versioned name for the json-serialzero0-unstable feature

Fixes

• Python implementation:
  • test suite:
    • drop the unneeded uvoxen dependency from the unit-tests group
• Rust implementation:
  • mtv-extract:
    • pin the version of the media-type-version dependency
