This week, a little surprisingly, a cumulative patch for Veeam Backup & Replication V11a was released:

This update comes especially to those customers who due to usage requirements need to maintain compatibility with older hypervisors ( for example VMware vSphere/Esxi 5.5).
The patch contains some product fixes, and also some security fixes of third-party components included in the software, such as VDDK, OpenSSL, liblz4, zlib and Putty:

Important note: If you decide to install this patch, you will no longer be able to upgrade to V12.1, but will have to wait for the release of the next minor update V12.2 (expected in the second half of 2024).
So if you are at V11 and have no compatibility issues with the rest of the infrastructure, the advice is to upgrade to the latest V12.1 version, taking advantage of the many added features immediately.
Below is one last link that may be useful when planning upgrades, the upgrade-path link for Veeam B&R.
