Review Board 5.0 Beta 2 Release Notes

Release date: August 17, 2022

Review Board 5.0 beta 2 drops support for Python 2.7. This has been end-of-life since January 2020. The 5.x series will support Python 3.7 through 3.10.

This release contains all bug fixes and features from Review Board version 4.0.10 and 5.0 beta 1.


To install this release, run the following:

$ sudo pip3 install \
    -f https://downloads.reviewboard.org/betas/reviewboard/5.0-beta-2/ \
    --pre -U ReviewBoard


We do not recommend upgrading a production server with this version of Review Board. It’s best to install on a test server, with a copy of your production database, in case there are any major problems.

New Features

  • Enhanced API tokens and token management.

    Since Review Board 2.5, users have been able to create API Tokens through the My Account page for use with RBTools or custom scripts using the Review Board API. These have historically been SHA1-based tokens.

    We’ve revamped API tokens in Review Board 5. They now support:

    • Expiration dates – tokens past an expiration date will no longer work

    • Invalidation – administrators can mark tokens as invalid and specify the reason

    • A larger length (255 characters), for security

    • Tracking the last-used date/time of a token

    • The ability to be scanned via secret scanning by checking an identifiable prefix (rbp__) and a checksum in the token

    All legacy tokens will continue to work, but we recommend moving to newer tokens for security.

    The API Tokens management page in My Account has been updated:

    • Tokens can now be copied with one click

    • The time a token was last used and how long until it expires or how long since it expired is now shown

    • If a token is invalidated, the date and reason why will be shown

    Additional UI for setting expirations will be added in the next beta release.

    Administrators can invalidate tokens through a new invalidate-api-tokens site management command.

  • Added debug logs for failed database upgrades.

    If there’s an issue upgrading the database, complete details will be logged to a file that can be used when contacting Beanbag Support to help diagnose and repair the issue.

Usability Improvements

  • The Install Key field in Administration UI -> Support Settings can now be copied with one click.


Bug Fixes

  • Improved performance of the auto-complete for the Search field.

  • Added protection against replay attacks for the new SAML Single Sign-On.

  • Updated SAML Single Sign-On to work when the Review Board server responds under multiple domain names.

  • Fixed a crash when trying to load extensions from broken Python packages.

  • Fixed a crash when a database issue causes multiple user profiles to be created for the same user.
