* - Add `unicode` feature to switch between `regex` and `regex-lite` as a trade-off between full unicode support and binary size. * Update CHANGES.md * Update CHANGES.md * refactor: move regexset code selection to own module * docs: add docs within RegexSet module * chore: restore manifests * test: ensure all actix-router codepaths are tested --------- Co-authored-by: Rob Ede <robjtede@icloud.com>
