After 9 months of development and testing we are pleased to announce the 
availability of Slurm version 20.11.0!

Slurm 20.11 includes a number of new features including:

- Overhaul of the job step management and launch code, alongside 
improved GPU task placement support.

- A new "Interactive Step" mode of operation for salloc.

- A new "scrontab" command that can be used to submit and manage 
periodically repeating jobs.

- IPv6 support.

- Changes to the reservation logic, with new options allowing users to 
delete reservations, allowing admins to skip the next occurance of a 
repeated reservation, and allowing for a job to be submitted and 
eligible to run within multiple reservations.

- Dynamic Future Nodes - automatically associate a dynamically 
provisioned (or "cloud") node against a NodeName definition with 
matching hardware.

- An experimental new RPC queuing mode for slurmctld to reduce thread 
contention on heavily loaded clusters.

- SlurmDBD integration with the Slurm REST API.

Please see the RELEASE_NOTES distributed alongside the source for 
further details.

Thank you to all customers, partners, and community members who 
contributed to this release.

As with past releases, the documentation available at 
https://slurm.schedmd.com has been updated to the 20.11 release. Past 
versions are available in the archive. This release also marks the end 
of support for the 19.05 release. The 20.02 release will remain 
supported up until the 21.08 release next August, but will not see as 
frequent updates, and bug-fixes will be targeted for the 20.11 
maintenance releases going forward.

Slurm can be downloaded from https://www.schedmd.com/downloads.php .
