If you mean what is different other than 0.5 then. Firstly on Spring Source's website has the details you need.

Whats new in 2.0 and 2.5

Whats new in 3.0

For my money, the differences that matter are:

3.0 required Java 5. 2.5 could work off Java 1.4

2.5+ limited Annotations are supported. 3.0 you can do everything in annotations.

Also new in 3.0:

• Spring Expresssion Language
• Spring Converters
• Adding Java Config module to Core Spring
• Spring RESTful Web Services are new
• More namespaces etc.
