Schema - v10.1/v11

• Separate branch catalogue_v10.1

• Release 4.7.3-1 / Deployed to Pre-Prod / Stress tests ongoing / Prod deployment TBD
• Release 4.7.4-1 / Freeze date TBD

• Version 4.7.3 is ready to be deployed to prod, but it was decided that we should wait for the stress tests to complete successfully. Vova will execute them this weekend. Following the result, we will decide when/if we will deploy it do production.
• Michael reminded that the release instructions have been updated. We should fill the %changelog part of cta.spec.in appropriately.

Public release:

• Only missing nightly runs and documentation fixes. After that the release should be ready.
• Michael will check with Steven how we can avoid having the Cern Oracle Instant Client as dependency, since it cannot be accessed outside of cern.

4 New CTA features

• Allow VO override for repack (#1210)
• Command to put down a disk instance (#1219)

• We will discuss this next meeting, when Julien is back.

5 dCache Integration

• Main issue: #1222

• Jacek will work on this together with another developer of their team.
• Michael suggested starting by having a build of the CTA Frontend using gRPC, in our repo. After that we would move to the other tasks, such as a version of cta-admin that uses gRPC.

6 AOB
