A quote from Gostev, in the Veeam Community Forums Digest mailing, send on august 4:
If you, or your customers are still using B&R 6.5, please keep in mind that we will stop supporting this version along with our v8 release, which is planned for early Q4. So please take the opportunity of slow summer time to perform the upgrade to v7. New releases typically increase load on our technical support team, which may in turn increase response times to handle possible upgrade issues (although frankly, we are not getting a lot of those for v7).
So if you’re still using Veeam 6.5 in production. Start working on your RFC to upgrade to Veeam v7.
