Test branches will be released periodically to allow users to try out new features and report any issues
You will need to have git installed. This installs the GitPython required by the Addon manager. You can download git here: https://git-scm.com/downloads
For non-developers, FreeCAD provides a mechanism for installing development versions using the Addon Manager. This option is not available by
default so you will need to enable it. From the Edit menu select Preferences.... In the left hand column select Addon Manager.
In the Advanced Options section check the Show option to change branches option. This will require a restart of FreeCAD to take effect.
Once restarted, select Tools and the Addon manager from the main menu. Scroll down to the Rocket workbench and select. In the installation menu you
will see the option Change Branch. Selecting this will bring up a list of branches allowing you to select the branch to test
VERY IMPORTANT
File formats in test branches may change and are typically not backwards compatible. If you open a file created with a previous version and save it with the test version you may not be able to open it again. Make sure you save anything important before testing. Even files created during testing may not be compatible with the final software version.
The best method for reporting problems is to create a new issue in GitHub. Please include information such as the development branch you're using, instructions on how to reproduce the error, and where relevant a copy of the file in which the issue was encountered. The more information you provide the easier it will be to pinpoint the problem.
For any feedback, features, and discussion please refer to the Rocketry workbench FreeCAD forum thread.
