Release 4.0 - Technology Preview
This is a preview release and is not recommended for production use.
Release 4.0 of the Session Border Controller is a major update that moves the system onto a new foundation and gives us an up-to-date platform on which to build. This will enable us to move quicker with patching security issues and enhancing functionality.
This preview release will allow users to evaluate the new platform and be ready for the upcoming production release. This release is functionally complete and tested for standalone systems. HA support will be coming in April 2025.
Due to the extent of the changes which have been made it is necessary to re-install the system from the 4.0 ISO when upgrading from 3.0. A system backup taken from 3.0 can be restored onto the 4.0 system and all settings will be migrated across.
