This merge request was triggered by a new tag being added to the fsl/slicetimer project.

Accepting this merge request will cause the conda recipe for fsl/slicetimer to be updated to version 2111.0.

If all goes well, a new conda package will built for fsl/slicetimer (2111.0), and will be uploaded to the FSL production conda channel.
