We have four releases today. First, Visual Studio 2013 Update 4 CTP 2 is available, including a few features (e.g. performance improvements for the Visual C++ browsing experience) and some bug fixes. Second, there’s also a CTP available for Team Foundation Server. The release notes have the complete list of features and fixes for both these releases.
Third, we also released Team Explorer Everywhere 2013 Update 2, which, among other things, improves how TEE stores credentials (making sign on to Visual Studio Online much easier) and adds the capability to browse Git repositories within TEE. Will Smythe has a full post here.
Finally, we released the Visual Studio Tools for Unity (VSTU) 1.9.1 on the Visual Studio Gallery: VSTU for VS 2013, VSTU for VS 2012, and VSTU for VS 2010. This release fixed many of the issues you reported on Connect in version 1.9.
I wonder if we'll see more CTP's this week? Seems like a while since we got a VS "14" CTP... :P
