Yesterday, Veeam released Veeam Backup and Replication 9.5 Update 4b, which contains some significant improvements: VMware vSphere 6.7 U3 support, Dell EMC Unity OE version 4.5 support, Microsoft Windows 10 May 2019 Update and Microsoft Windows Server version 1903 support as guest VM and others… This build is fully supported by Veeam technical support, who is standing by to assist all early adopters. If nothing unexpected pops up (especially around 3rd party platform updates), Veeam B&R Update 4b should hopefully be the last version 9.5 build. The next planned release vehicle is version 10, which goes into the private beta later this month, and is expected to be shipped before the end of this year.
