Bugfixes

No bugfixes.

Breaking changes

The following breaking changes were introduced:

• Java 17

  Valtimo is now compiled on Java 17 and needs to run in a Java 17 environment.

• View configurator module

  The view configurator module that was used by the old AngularJS front-end has been removed.

• Process data object relation

  Process data object relations were a way to link a stored object to a running process. When document definitions were introduced, this functionality was made obsolete. Process data object relations have now been removed.

• REST API versioning

  Every REST endpoint exposed by Valtimo now contains a version, e.g. /api/document becomes /api/v1/document. This makes it easier to support multiple versions in the future in case of breaking changes in the REST API, without waiting for a new major version of Valtimo.

• Removed deprecated code

  A number of deprecated methods and classes have been removed, and as a result some implementations need to make minor changes.

• Removed JWT configuration properties

  The properties valtimo.jwt.base64encoding and valtimo.jwt.tokenValidityInSecondsForRememberMe have been removed as they were used in a module that is no longer supported.

Instructions on how to migrate to this version of Valtimo can be found here.
