Migrating from earlier versions of the Spring Framework

This page provides information when upgrading to newer versions of the Spring Framework. If you find items not covered yet, please raise a ticket in JIRA or submit a pull-request against this page.

For information pertaining to new features a given release, consult the What's New in the Spring Framework wiki page.

Actively supported generations: 3.2, 4.2, 4.3

Note that the 3.0.x and 3.1.x lines have been retired already, with no support whatsoever available anymore, in favor of the 3.2.x line (EOL is December 31 2016, see this blog announcement).

Limited support for 4.1.x is still available but no further maintenance releases are planned in that line. We strongly recommend an upgrade to the latest Spring Framework 4.2.x release or - preferably - to the 4.3 line: http://projects.spring.io/spring-framework/
