Included are several improvements in web UI and various fixes throughout the system. See our YouTrack installation for the full list.
This is a minor upgrade so you can probably do light version of upgrade (comparing to the full instructions).
This light approach is:
- Create backup of your data from TeamCity Administration UI (backing up database and configuration data)
- Install the updated TeamCity version over your existing one. The simplest way to do that is to:
- stop the server
- backup your <TeamCity home>/webapps/ROOT directory
- delete it's content
- unpack TeamCity-5.1.5.war (this is a zip archive) into the directory
- start the server
