• Introduction of async history. By enabling the asyncHistoryEnabled property on the process engine configuration (default is false), the history tables are not filled in the same transaction as the runtime tables. Instead an async history job is created and the history information will be written to the history tables in a separate, asynchronous transaction. This also opens up the option to not use the relational history tables at all, and move the historic information to a NoSQL database directly. Pluggability points are available to implement the persistence logic to a NoSQL database.
• New REST task feature thanks to Harsha. With the new REST task it becomes trivial to do REST calls from a Flowable process instance. There's also support in the Flowable Modeler for REST tasks.
• Introduction of a new DMN decision table editor. To improve the usability of the DMN decision table editor we are now using the Handsontable framework.
• The Engine SQL update logic has been improved to only update changed columns.
• The Odysseus JUEL code is now included directly in the flowable-engine-common module to prevent classloading issues due to conflicting JUEL libraries or even different versions of JUEL libraries.
• Added option to use a password encoder for the Flowable IDM engine (instead of the default plain text password persistence), thanks to Faizal!
• Support for static Groovy scripts compilation with the new flowable-groovy-script-static-engine module by using the groovy-static scriptFormat value, thanks to Filip (fgroch)!
• Several additions to the Form builder and renderer (min/max length, improved expression field and more).
• Various small bugfixes all around.
