RBTools 6.0 Release Notes¶

Release date: February 9, 2026

Installation¶

Follow our installation guide to install RBTools.

To learn more, see:

RBTools supports Python 3.10 through 3.14.

Support for Python 3.8 and 3.9 has been dropped. For continued support on those versions, please use RBTools 5.x.
Added a dependency on appdirs. This replaces a previously bundled copy.
Added a dependency on typelets 1.1.x.

Added support for Jujutsu

Jujutsu is a version control system which works seamlessly with Git servers while providing new and innovative concepts and commands. Because of its interoperability, it’s a powerful tool that can be integrated into individual developer workflows without requiring major organizational changes.

RBTools 6.0 includes full support for working with Jujutsu clones, including posting, patching, and landing changes.

Full documentation and type hinting for all resources.

The Python API part of RBTools automatically generates client-side bindings by introspecting API payloads. While this allowed the bindings to be used for all APIs, including those in custom extensions, it made it difficult to work with because things like method names were not properly documented.

The API now includes custom resource subclasses to match all resource endpoints in Review Board. These provide documentation and type hints for the entire API surface.

Under the hood, the API still uses introspection, so you can still use it with your extension-provided API endpoints.
Allow the --open-browser and --web-login options to be used for all commands.

Web-based login (introduced in RBTools 5.0) was only supported for the rbt login command, which meant that the login prompts used for other commands when there was no current session would not allow it. This has been changed so if the server supports web-based login, it can be used at any point.

Apply patches to binary files.

As of Review Board 7.0 and RBTools 5.0, posted changes may include binary files in diffs. This is limited to reviewable file types such as images. “rbtcommand:rbt patch will now download these files and apply them as part of the patch.

This is supported for Jujutsu, Git, Mercurial, Perforce, and Subversion.

Fixed an issue where an incorrect warning about private user profiles could be shown.

Fixed some potential issues with commit messages and authors when squashing multiple commits.
Fixed patching on Mercurial to use –config patch.eol=auto in order to more reliably apply patches in files with varying newline styles.
