SBT runner bundled

Simple Build Tool (Scala) plugin is now bundled with TeamCity.

Unidirectional protocol

Unidirectional protocol announced in previous EAP is now enabled by default.

To change the communication protocol for all agents, set the teamcity.agent.communicationProtocols=xml-rpc internal property.

You can configure unidirectional communications in the agent's properties file by setting the teamcity.agent.communicationProtocol=polling property.
