No noteworthy changes

From 3.0.1 to 3.1

Guest User and Agent Details

Starting from version 3.1, the Guest user does not have access to the agent details page. This has been done to reduce exposing potentially sensitive information regarding the agents' environment. In the Enterprise Edition, the Guest user's roles can be User Accounts to provide the needed level of permission.

StarTeam Support

Working Folders in Use

Since version 3.1 when checking out files from a StarTeam repository TeamCity builds directory structure on the base of the working folder names, not just folder names as it was in earlier versions. So if you are satisfied with the way TeamCity worked with StarTeam folders in version 3.0, ensure the working folders' names are equal to the corresponding folder names (which is so by default).

Also note, that although StarTeam allows using absolute paths as working folders, TeamCity supports relative paths only and doesn't detect absolute paths presence. So be careful and review your configuration.

StarTeam URL Parser Fixed

In version 3.0 a user must have followed a wrong URL scheme. It was like starteam://server:49201/project/view/rootFolder/subfolder/... and didn't work when user tried to refer a non-default view. In version 3.1 the native StarTeam URL parser is utilized. This means you now don't have to specify the root folder in the URL, and the previous example should look like starteam://server:49201/project/view/subfolder/...

From 3.0 to 3.0.1

Linux Agent Upgrade

Due to an issue with Agent upgrade under Linux, Agent auxiliary Launcher processes may have been left running after agent upgrades. Versions 3.0.1 and up fix the issue. To get rid of the stale running processes, after automatic agent upgrade, please stop the agent (via agent.sh kill command) and kill any running java jetbrains.buildServer.agent.Launcher processes and start the agent again.

From 2.x to 3.0

Incompatible changes

Please note that TeamCity 3.0 introduces several changes incompatible with TeamCity 2.x:

build.working.dir system property is renamed to teamcity.build.checkoutDir. If you use the property in you build scripts, please update the scripts.
runAll.bat script now accepts a required parameter: start to start server and agent, stop to stop server and agent.
Under Windows, agent.bat script now accepts a required parameter: start to start agent, stop to stop agent. Note that in this case agent will be stopped only after it becomes idle (no builds are run). To force immediate agent stopping, use agent.bat stop force command that is available under both Windows and Linux (agent.sh stop force). Under Linux you can also use agent.sh stop kill command to stop agents not responding to agent.sh stop force.

Build working directory

Since TeamCity 3.0 introduces ability to configure VCS roots on per-Build Configuration basis, rather then per-Project, the default directory in which build configuration sources are checked out on agent now has generated name. If you need to know the directory used by a build configuration, you can refer to <agent home>/work/directory.map file which lists build configurations with the directory used by them.
