Veeam released V7a of VB365 just recently (Dec 5th, 2023).
The KB for the patches to 7.0 has all the changes of 7.0.x: https://www.veeam.com/kb4425
With a new major release (e.g. V7) we get the changes within the “what’s new” document: https://www.veeam.com/veeam_backup_m365_7_0_whats_new_wn.pdf
There does not seem to be a “what’s new” document for 7a (7.1.x). Here I can only find the full release notes which makes it kind of hard to determine changes.
Did anyone find the specific changes within 7a already?
