The latest version of Matlab, R2021a, is available for departments that have licenses. The software and license codes can be obtained through a mail to postmaster for those entitled to it. The software can also be found on the install-disc. All C&CZ-managed Linux machines will soon have this version installed, an older version (/opt/matlab-R2020a/bin/matlab) is still available temporarily. The C&CZ-managed Windows machines will not receive a new version during the semester to prevent problems with version dependencies in current lectures....

From now on, C&CZ signs the SSH keys of e.g. loginservers and compute clusternodes. That makes it possible for users, as explained on that page, to add the public signing key in the private .ssh/known_hosts, which makes one trust all C&CZ signed SSH servers. Whenever C&CZ deploys a new ‘lilo’, the question whether this might be spoofing will not occur then.

The old installation method, used with Matlab R2020b, highlighted several problems for some users. The solution was found in a different installation method. Some users will prefer the new method, others the old one. Each has its pros and cons. The new installation method makes Matlab easy to install, also for older versions and can be done with a small download if you only want a few toolboxes. But it requires signing in at The MathWorks and thus has a more complex workflow....
