  Selenium publishes a dated, per-release changelog in three coordinated places: a GitHub release
  per version, a per-binding CHANGELOG/CHANGES file in the monorepo (java/CHANGELOG, py/CHANGES,
  rb/CHANGES, dotnet/CHANGELOG, javascript/selenium-webdriver/CHANGES.md — all 200 on 2026-08-26),
  and a narrative announcement post on the project blog. Entries below are read from the JavaScript
  CHANGES.md, which is representative of the shared monorepo change set.

notes:
  - >-
    A `nightly` pre-release tag is published continuously alongside the stable train (last seen
    2026-08-26).
  - >-
    The wire contract itself does not move with these numbers. Nothing in 4.41–4.47 changed a W3C
    WebDriver HTTP endpoint; the churn is in the BiDi schema, the bindings and Grid.
  - >-
    Release announcements go back to 2010 on the project blog, which is an unusually long dated
    change record for any provider in this catalog.
