Review Board 5.0.1 Release Notes

Release date: November 2, 2022


To upgrade to this release, run the following using a compatible version of Python:

$ sudo pip3 install ReviewBoard==5.0.1

And then perform an upgrade of your site. See Upgrading Review Board for details.

Known Issues

  • Single Sign-On is currently broken out of the box on Python 3.11, due to issues with a couple of third-party dependencies.

    Users should be able to work around this by running:

    $ sudo pip3 install 'ReviewBoard[saml]'
    $ sudo pip3 install --force-reinstall --no-binary lxml lxml

New Features

  • Added deprecation notices for old-style API tokens.

    API tokens constructed before Review Board 5 will now show as deprecated in the My Account page -> Authentication page. This helps identify tokens that should be replaced for security reasons.


  • Added a deprecated field to API Token Resource showing whether a token has been deprecated.

  • API requests made with deprecated API tokens now contain a X-API-Token-Deprecated HTTP header containing a message to display.

  • Fixed a Python version-specific inconsistency in the URI templates in Root List Resource.

    Depending on the version of Python being run, URI template names would sometimes map to different locations. This was a problem in Review Board 4 and 5.

    We’ve taken a hard look at this, and have fixed this to use the mappings consistent with Python 2.7, as those have been in use the longest. This may affect some clients of the API.

    Steps were taken to ensure these inconsistencies can’t happen again.

Bug Fixes


  • Fixed a generation problem with API tokens created in Review Board 5.0.

    These tokens use a Base62-encoding, but the character set used was wrong. This led to tokens that weren’t exactly Base62.

    This is fixed in this release, and only affects consumers looking to validate tokens through custom code. Review Board still considers these tokens valid.

  • Fixed a small inconsistency with the Single Sign-On “Log in” button.

    This button now says Log in instead of Login, matching the other buttons.

Review Requests

  • Fixed a breakage when uploading diffs in the New Review Request page after filtering the list of repositories. (Bug #4981, Bug #4982)

  • Fixed a bug where the dropdown besides the “Publish Review” button could close the Review Dialog. (Bug #4944)

    Patch by Mike Conley.


  • Hosting services that fail to load (for example, due to missing extensions) now result in proper error messages and not crashes or bad behavior.

    This was most noticeable with Git hosting services. If the service failed to load from an extension, Review Board would attempt to access the repository directly, but this most often would not work, and would lead to confusing errors.

  • Fixed a crash in GitLab when localizing some authentication errors.
