+* Added support for Java 17.
 * Updated ProB 2 to version 4.0.0-SNAPSHOT.
 * Added a `:language` command to allow changing the language used to parse user input. For example `:language event_b` can be used to switch to Event-B syntax when a non-Event-B machine is loaded (or no machine at all).
 * Improved the performance of loading machines by reusing the existing instance of ProB instead of starting a new one for each machine.
