Expected dependencies for SNAP v9

I’m aware what SNAP v9 is expected to be released later this year (European summer?) and I was wondering if it’s possible to find out what the dependencies will be. The main one is the GLIBC version, will it still be v2.23?

I’m in the process of developing a new workflow with a HPC using v8 but I need to update the GLIBC version for this to occur. I don’t want develop this if the GLIBC version is going to change shortly.
