The new version 14.0.2 has been released and can be downloaded at the Microsoft Download Center.
Brian Harry self-effacingly called it “small update”. However for the teams at many companies who have been using TFVC but want to gradually move to Git, it has a huge update: you can now use both in the same team project.
This allows you to get to work without losing your context: you just incrementally move relevant pieces of your code from one repo to another. Previously you had to change context every time you were working on big code bases that lived partially in one place or another. I am now experimenting with it for builds to see if it allows the same ease of transition.
