We have invested heavily in the 4.x platform over the last couple of years and we’re now at the stage where we can release 4.x on a similar cadence to that we achieved with the 3.x series.
4.3 reached feature parity with 3.12 and supports the same DMA and Meeting Management functionality.
We strongly advise customers to start planning to migrate to 4.3 or higher sooner than later.
There is a real risk that vulnerabilities are found within the CentOS Operating System and because of the end of support and declining activities of the CentOS community, they are not fixed and are not fixable.
Migrating to 4.x will require a new VM. We provide tooling to export and import the data from 3.x into 4.x.
More details can be found in the 3.12 and 4.3 and above release notes.
