26.0 Galaxy Release (April 2026)

Please see the 26.0 user release notes for a summary of new user features. The GitHub Release Notes provide a comprehensive overview of all changes.

Get Galaxy

The code lives at GitHub and you should have Git to obtain it.

To get a new Galaxy repository run:

$ git clone -b release_26.0 https://github.com/galaxyproject/galaxy.git

To update an existing Galaxy repository run:

$ git fetch origin && git checkout release_26.0 && git pull --ff-only origin release_26.0

See the community hub for additional details on source code locations.

Admin Notes

Galaxy is now exclusively licensed under the MIT License: Galaxy has completed its transition from the Academic Free License (AFL) to the MIT License. All prior contributions have been re-licensed under MIT with contributor approval. This resolves long-standing compatibility concerns for downstream Linux distribution packagers (e.g., Debian) and simplifies licensing for all Galaxy Python sub-packages.

Developer Notes

Client Build Toolchain Modernized: Vite, Vitest, and Removal of Webpack/Gulp

The Galaxy client build system has been completely overhauled in 26.0. Webpack has been replaced by Vite for bundling, Jest has been replaced by Vitest for unit testing, and Gulp has been replaced by a plain Node.js script for pre-build tasks (icons and visualization plugins). These changes put the entire client on a single modern toolchain and result in significantly faster builds (~35s) and test runs (~22s for the full suite).

Contributors writing client tests should update their files to use Vitest APIs (vi.fn(), vi.mock()) and import test utilities explicitly (describe, it, expect, etc.) rather than relying on globals. The test environment has also switched from jsdom to happy-dom, removing the need for several manual polyfills. Pre-build shortcuts yarn icons, yarn plugins, and yarn plugins-rebuild are also now available.
