3.15 (2026-05-12)
- Enforce DNS-length cap on individual labels early in
check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.- Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared
_unicode_dots_refromidna.corein the codec module.- Use
raise ... from errfor proper exception chaining and switch internal string formatting to f-strings.- Allow
flit_core4.x in the build backend.- Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
- Add Dependabot configuration for GitHub Actions.
- Convert README and HISTORY from reStructuredText to Markdown.
- Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.
Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.13 (2026-04-22)
