Galaxy Release 21.05

Workflow Reports, Remote Files, Visualizations

June 10th 2021

We are pleased to announce the release of Galaxy 21.05 - developer and admin release announcement and user release announcement.

Highlights

New development stack

Galaxy release 21.09 will ship with a new web framework (fastAPI), Celery task queue and process management using Circus. You can preview new stack now by running APP_WEBSERVER=dev ./run.sh.

Celery for background tasks

Galaxy can now run certain tasks in the background. The Celery workers are currently not required, but if activated can perform certain long-running tasks, such as creating history export archives. Celery tasks will bridge the gap between rapid requests that can be handled during a web request and jobs that require extensive and relatively slow setup.

More robust selection of job handlers

Job throughput can be increased by starting Galaxy with multiple external job handler processes. Jobs were traditionally assigned to a job handler process by the web handler or workflow handler process that created the job. Since Release 19.01 Galaxy has supported additional mechanisms that use database serialization techniques to let job handlers assign processes to themselves. This mechanism is more robust and doesn't require that all job handler processes be alive and known by the web handler process. Galaxy now determines the best method for assigning jobs based on the database in use, if the assignment method is not set explicitly. Older job assignment methods will be removed in Galaxy release 21.09. For more details see the Job Handler Assignment Methods section of the Galaxy documentation.

¡Galaxy, ahora en español!

Thanks to Wendi Bacon, the Spanish language translation of Galaxy has been finalised and merged, so if you prefer to use Galaxy in Spanish, now you can! This update will be part of an ongoing project from Spanish speakers within the Galaxy community to keep the Galaxy interface localisation up to date, and to produce some Spanish language training materials in the GTN.

Bugfixes and Stability

This release of Galaxy features fewer user-facing changes, as a huge amount of developer time went into making this a maintenance release with better testing, better stability, and more bugfixes. But watch out, this is all in preparation for the next release of Galaxy, 21.09, which will have some of the biggest UI changes in years!

Remote Files: FTP Support

In the last release, the Remote Files interface was added granting access to a huge number of remote data sources directly in Galaxy. Support was added for FTP servers in the latest release so now you can connect e.g. the NCBI FTP server for all of your genomic data needs.

##Download Collections from Reports## Workflow reports are gaining popularity and features! You can not only insert previews of collections in your reports, but also download them directly from the report interface.

New Visualizations

Thanks to @dlal-group, the SimText suite of tools has been added as an interactive tool within Galaxy. You can read about how to use this new Interactive Tool in the associated GTN tutorial.
