why would you upgrade to latest version?

[cablepuff]

here is a general question, why move from spring 2.5 to spring 3.0.4

why move from web flow 2.0.8 to say webflow 2.2.1

why move from spring security 2.0.4 to 3.0.3 release...


Give the key changes and/or improvement and why you would upgrade.

Many reasons:

New features are introduced in new versions.

Bugs get fixed.

When you do bump into a bug, you don't waste everybody's (including yourself) time digging into it, just to find out it was fixed in a newer version.

Performance improvements in the code or its dependencies.

If you don't upgrade periodically, you may find it harder to upgrade later when you do want a new version for a specific fix or feature.

Everyone using the latest version makes it easier to collaborate, both inside Spring projects and in projects that use Spring as a dependency.
