Grails 3.3 GA Released
July 26, 2017
Grails 3.3 includes a number of significant improvements, most notably to GORM with GORM 6.1, which we released earlier in order to gather feedback from Grails 3.2.x users.
GORM 6.1 includes some real breakthrough innovations, including Data Services that allow you to define interfaces that are automatically implemented and work seamlessly with GORM's multi-tenancy features.
Other highlights of Grails 3.3 include the new EventBus abstraction which integrates with existing reactive libraries such as RxJava. Events are also for the first time transaction aware so that consumers are only notified if the surrounding transaction is successful, which simplifies code greatly.
