Today we released Teamprise V1.1 to the general public (available here). Version 1.1 is a maintenance release to address several issues that our customers have reported. Most notably, Version 1.1 now fully supports NTLM authentication (including NTLMv2). If you were previously unable to connect to your Team Foundation Server then we urge you to try this release. Version 2.0 will be available later this year and will include work item editing features along with additional source control functionality (users purchasing Version 1 will get a free upgrade to Version 2.0 when it becomes available).

If you're not familiar with the product, the description on their site says it all: "Teamprise is a suite of client applications for accessing Microsoft Visual Studio 2005 Team Foundation Server from outside of the Visual Studio Integrated Development Environment (IDE). Teamprise enables software development teams to use the source control and work item tracking features of Team Foundation Server from within the Eclipse IDE, and from other operating systems, including Linux and Mac OS X."
