Redmine 2.5.1 is a maintenance release that includes a security fix (wrong validation of the URL where the user is redirected to after logging in, reported by Minoru Sakai). You can review the other changes in the Changelog. Redmine 2.4.5 includes the security fix only.
Redmine 2.5.0 is a new feature release available for download.
It brings many improvements to custom fields formats: text formatting support, HTTP link support, fine-grained selection for user and version custom fields based on roles and version status. The custom field format API was fully rewritten, so if you're running some plugins that deal with it (eg. that adds non standard field formats), you'll have to update them before upgrading. This version also introduces experimental support for Markdown formatting, a popular text formatting syntax. You can review the list of all changes in the Changelog.
Redmine 2.4.4 is a maintenance release that fixes a few defects and upgrades Rails to 3.2.17.
