Version 3.4.2

3.4.2 (2025-05-02)

Fixed

• Addressed the DeprecationWarning in our CLI regarding argparse.FileType by backporting the target class into the package. (#591)
• Improved the overall reliability of the detector with CJK Ideographs. (#605) (#587)

Changed

• Optional mypyc compilation upgraded to version 1.15 for Python >= 3.9

Version 3.4.1

🚀 We're still raising awareness around HTTP/2, and HTTP/3!

Did you know that Internet Explorer 11 shipped with an optional HTTP/2 support back in 2013? also libcurl did ship it in 2014[...] Using Requests today is the rough equivalent of using EOL Windows 8! We promptly invite Python developers to look at the first drop-in replacement for Requests, namely Niquests. Ship with native WebSocket, SSE, Happy Eyeballs, DNS over HTTPS, and so on[...] All of this while remaining compatible with all Requests prior plug-ins / add-ons.

It leverages charset-normalizer in a better way! Check it out, you will gain up to being 3X faster and get a real/respectable support with it.

3.4.1 (2024-12-24)

Changed

• Project metadata are now stored using pyproject.toml instead of setup.cfg using setuptools as the build backend.
• Enforce annotation delayed loading for a simpler and consistent types in the project.
• Optional mypyc compilation upgraded to version 1.14 for Python >= 3.8

Added

• pre-commit configuration.
• noxfile.

Removed

• build-requirements.txt as per using pyproject.toml native build configuration.
• bin/integration.py and bin/serve.py in favor of downstream integration test (see noxfile).
• setup.cfg in favor of pyproject.toml metadata configuration.
• Unused utils.range_scan function.

Fixed

• Converting content to Unicode bytes may insert utf_8 instead of preferred utf-8. (#572)
• Deprecation warning "'count' is passed as positional argument" when converting to Unicode bytes on Python 3.13+

Version 3.4.0

🚀 charset-normalizer is raising awareness around HTTP/2, and HTTP/3!

Did you know that Internet Explorer 11 shipped with an optional HTTP/2 support back in 2013? also libcurl did ship it in 2014[...] All of this while our community is still struggling to make a firm advancement in HTTP clients. Now, many of you use Requests as the defacto http client, now, and for many years now, Requests has been frozen. Being left in a vegetative state and not evolving, this blocked millions of developers from using more advanced features.

We promptly invite Python developers to look at the drop-in replacement for Requests, namely Niquests. It leverage charset-normalizer in a better way! Check it out, you will be positively surprised! Don't wait another decade.
