How to update this file

When you make a change that affects users or developers, add a brief entry under the [Unreleased] section describing:

  • What changed
  • Why it matters (when not obvious)
  • Whether it is breaking, additive, or a bug fix

When you cut a new release:

  1. Create a new version heading (for example, ## [0.3.0] - 2025-03-15).
  2. Move relevant entries from [Unreleased] into that version section.
  3. Commit the updated changelog as part of the release commit.
