== News
HTCondor have renewed interest in REST interface. aCT client is being tested in Oslo, using an HTCondor cluster. KIT is moving to CondorCE (run HTCondor as well). There's interest at KU to use LUMI instead of the local HPC, so ARC can be interfaced to it, if the NeIC proposal is approved.
== GridFTP deprecation and replacement with REST
Two key questions from HTCondor:
a) Is there a planned version (or date) when the GridFTP interface will become obsolete and this work [REST interfacing] will need to be done?
b) Similarly, for the REST interface, what's the minimum supported ARC CE version they should be targeting
Specification is almost complete, except for the error handling and error messages which got delayed due to Covid. Balazs and Andrii will check Aleksandr's comments if they are implemented in the specification. Hopefully in one week the specs will be ready. Coding will take probably a couple of months, so by the end of the year REST implementation can be ready. Won't be a major release yet, as it shouldn't break anything, hopefully.
GridFTP can be marked obsolete in ARC7, but will be still released.
== Bugs
No new bugs, nothing worth noting.
== AOB
A meeting about ARC7 is needed, but should be Zoom-only if we want it soon. Clustering of people is possible.
An accounting expert is needed.
