This release includes significant user interface changes enhancing accessibility and usability. This includes a new tool search, modernized multi-history view, new tag displays, theme support, and better drag and drop handling across the application. There are also brand new ‘Datatypes’ and ‘About This Galaxy’ interfaces. Interactive Tools are more seamlessly integrated into the user interface and Galaxy also comes with a new MGnify Notebook IT. The workflow editor has been completely overhauled with significant improvements to usability and extensibility, including new conditional workflow step functionality.

Administration Notes

Dependencies for various built-in converter tools have been changed from pysam to samtools. Please make sure you install these dependencies through the admin panel or manually. See more details on the PR here.

Configuration default values are no longer read from the sample files – they now come directly from the config schema. If you are relying on local changes to sample files, be aware that you will need to adjust your configuration. See more details on configuration changes on the PR here.
