Struts is still widely used by server-side Java developers, but I have stopped tracking it after the release of Struts 1.1 more than a year ago. So it's no surprise that I didn't notice the release of Struts 1.2.2 until now.
Scanning through the Release Notes, I don't see any compelling reasons to upgrade. Even worse, there are good reasons to not upgrade, like removal of code deprecated in 1.1 which will break some existing code.
I don't think I'll be upgrading my Struts 1.1-based projects and, for new java webapp projects, I'll be using the Spring Framework.
So long and thanks for all the actions, Struts. It's been fun watching the paint dry.
