[dependabot]

Updates the requirements on idna to permit the latest version.

Changelog

Sourced from idna's changelog.

3.12 (2026-04-21) +++++++++++++++++

• Update to Unicode 17.0.0.
• Issue a deprecation warning for the transitional argument.
• Added lazy-loading to provide some performance improvements.
• Removed vestiges of code related to Python 2 support, including segmentation of data structures specific to Jython.

Thanks to Rodrigo Nogueira for contributions to this release.

3.11 (2025-10-12) +++++++++++++++++

• Update to Unicode 16.0.0, including significant changes to UTS46 processing. As a result of Unicode ending support for it, transitional processing no longer has an effect and returns the same result.
• Add support for Python 3.14, lowest supported version is Python 3.8.
• Various updates to packaging, including PEP 740 support.

3.10 (2024-09-15) +++++++++++++++++

• Reverted to Unicode 15.1.0 data. Unicode 16 has some significant changes to UTS46 processing that will require more work to properly implement.

3.9 (2024-09-13) ++++++++++++++++

• Update to Unicode 16.0.0
• Deprecate setup.cfg in favour of pyproject.toml
• Use ruff for code formatting

Thanks to Waket Zheng for contributions to this release.

3.8 (2024-08-23) ++++++++++++++++

• Fix regression where IDNAError exception was not being produced for certain inputs.
• Add support for Python 3.13, drop support for Python 3.5 as it is no longer testable.
• Documentation improvements
• Updates to package testing using Github actions

Thanks to Hugo van Kemenade for contributions to this release.

3.7 (2024-04-11) ++++++++++++++++
