Recent changes:

  • #349: Specify the default backend for loading JWT X.509 fingerprints to maintain compatibility with older versions of cryptography – thanks @dabaer
  • #342: Additional Linux GUI dependency setup documentation – thanks @strikegun79
  • #351: Support a non-standard variant of ROPCG used by 21Vianet, and more robustly handle cases where expires_in is not returned as an integer – thanks @Eric-ZhehanZ
  • #357: Fix a configuration file path issue when using Nuitka – thanks @Selwoir for reporting
  • #360: Add link to example Helm Chart – thanks @pjaudiomv
  • Better debug logging of JSON message content when token-related errors occur
  • Add support for PKCE code challenges (required by Fastmail and Comcast; optional for various other providers/configurations)

Please note that the pre-built executables provided here are packaged automatically directly from the source using PyInstaller and Nuitka. There is no difference between these versions except for the way in which they are packaged, so it is fine to choose either option. However, while these versions of the proxy are provided for your convenience, they are not officially supported. In addition, it is possible that you will see false positive warnings about these files (from, e.g., Microsoft Defender). This is not an issue with the proxy itself, but if it helps you are welcome to report this problem to the various scanning providers (e.g., see this previous discussion), which normally resolves the alert for that version of the proxy.
