What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- Replace `htpasswd` file parser with a custom implementation to migrate off unmaintained
  `passlib` dependency. The new parser only supports bcrypt and SHA-1 hashing.
  Contributions for additional formats are welcome as long as they don't introduce new
  dependencies.
