Acronis has released and we have tested version 11.7.50058. This is considered update 1 by Acronis. Its similar to a Service Pack for Windows. There are quite a number of bug fixes. We recommend upgrading, but as long as you are not seeing issues, there is no urgent need to upgrade.
Upgrading a machine already on 11.7 is a simple. Just download the installer and upgrade. Your cloud storage node will need to be upgraded first so please put a ticket in with support if you want to upgrade.
If you are on 11.5, the same rules apply as moving to 11.7. We can upgrade in place for bug fixes but the vault will still be on 11.5 and will not use the improved deduplication algorithms.
