Maintenance Policy

Adding Environments

Whenever a new version of one of the following environments is released, we target support of that new version with the next minor release of Camunda. A new released environment has to be available three months before the next Camunda minor release to be considered.

• Java Language (LTS)
• Spring Boot
• Wildfly Application Server
• Oracle Database (LTS)
• PostgreSQL

The exact release in which we support a new environment depends on factors such as the release date of the environment and the required implementation effort.

Version support for other environments is decided case by case, much of which is based on the demand in our user base.

Removing Environments

Whenever a new version of one of the following environments is supported, we usually discontinue support of the oldest version with the same release:

• Wildfly Application Server

Note that we may decide to deviate from this policy on a case-by-case basis.
