GrailsFlow 0.1, Released 08/16/2007

• Basic workflow engine
• Support for multiple nodes types (interactive, non interactive)
• Worklist for simple UI
• Process editor to edit process definitions, variables etc.
  

GrailsFlow 0.2, Released 10/31/2007

• Improved process editor with graphical preview of processes
• Process definition is now done using builders (more Groovy)
• automatically generated forms to work with process variables in the worklist (eg. a form that includes all variables and allows to edit them)
• Support for user defined forms and controllers
• Improved support for due dates and timeouts
• Basic reports to check the status of processes
• Analysis report to check min./max./average runtime of processes
  

GrailsFlow 0.3, Released 02/20/2008

• Action Editor with a user friendly UI to define actions that get executed, when entering a node
• Implemented ActionBuilder (executes actions, resolves action calls to action classes) and enhanced ProcessBuilder to deal with actions
• Document and Document Attachments for processes are defined as simple variables for a process and can be uploaded, updated and downloaded. Document attachments have a simple versioning system that allows to see the full history of documents.
• Fixed and enhanced tests and test scripts, added test actions actions
• GrailsFlow ported to Grails 1.0
• Minor improvements like predefined selection criterias, javascript date selection etc.

Planned for GrailsFlow 0.4 (may become GrailsFlow 1.0 RC1)

• Support for asynchronous calls, remote calls and webservices
• Create a GrailsFlow Plugin for Grails
• Improved storage of actions: allow arbitrary Groovy code instead of a simplified builder syntax
• Rename "worklist" to "inbox"
• Pluggable user management (using existing plugins like Acegi security or JSecurity)
  
• Reuse Ant Tasks and Grails Service classes as Actions in the workflow engine

Planned for later versions/further ideas

• Support for sub-processes (nested processes)
• Improvement of the workflow execution speed (execution of nodes; NodeActivator)
• New "start work" option that allows to track the time needed for the execution of the activity (instead of the pure waiting time)
• More analysis reports, eg. number of workflows that are open/discarded/closed per week/month/quarter..
• Simulation of processes/calculation of the execution time of processes
• web based fully graphical editor for processes (using the existing Ajax/Javascript libaries)
• Include the notion of "actors/groups/roles" to simplify process defintions and to allow for "swimlane" diagrams
