Verj.io releases include new Application Containers. All Service Plans will be upgraded to the latest Verj.io Version after that version becomes publicly available.
An announcement will be made at the time of the release detailing when Service Plans will be upgraded to this version.
During this time, it is recommended that your application is tested using the newly released Studio to make sure your application will continue to operate as expected after it has been upgraded.
More details can be seen in the Verj.io Version policy.
