subject: Noether framework (emmiai-noether)
scheme: mixed (semver through 2.0.0, calendar-based from 2026.4.0)
current_version: 2026.4.0
current_version_released: '2026-04-29'
last_checked: '2026-08-17'
currency_note: >-
  Re-checked 2026-08-17: 2026.4.0 is still the newest PyPI release (uploaded
  2026-04-29) and the newest git tag (v2026.4.0) - no new version in ~3.5 months,
  though the default branch keeps taking commits. Two source caveats worth
  recording: the GitHub Releases API now returns an empty array for this
  repository (the four versions exist as tags only), and the in-repo CHANGELOG.md
  has not been regenerated past 2.0.0 (2026-03-27), so the 2026.4.0 entry below
  is the only surviving structured capture of that release.
