The 2nd anniversary of the announcement that Spring 2.5 was available is just around the corner. There are many reasons to upgrade the SpringFramework from 2.0 to 2.5. Spring 2.5 is designed as a drop-in replacement for 2.0 so there are no valid technical arguments for not upgrading.
Release Announcement: 19/11/2007
I don’t want to review all the improvements that were made, but thought it would be interesting to pick a favorite feature and explain why for me its the best feature. Perhaps some of the few remaining projects out there will move up and start taking advantage of this fantastic framework. After all, with the release notice for 3.0 RC1 back in September soon there will be reasons to upgrade again!
