As already reported in various places (including lwn.net and Linus Torvalds), the most notable feature in this release is unarguably the improved support for the pull-request based workflow, in which participants can exchange their histories more securely, even over a potentially untrustable hosting service. This is truly an end-to-end support, starting from the inception of a topic branch with its own description, use of the branch description and the message in a signed tag in a pull-request message, use of the message in a signed tag in the resulting merge commit and verification of the signature when reviewing the resulting history (see this for a tutorial).
There also are many other updates that hopefully make working with Git a more delightful experience. Highlights are:
- "Credential helper" support, that allows integration of HTTP authentication with platform-native key-chain implementations;
- New progress eye-candy output for a couple of lengthy operations e.g. fsck;
- I18N framework enabled for both C and scripted Porcelains;
- Improvement in prompted input from an interactive terminal (most notably, reading the username for HTTP authentication);
- You can now run "git checkout -B <current branch> <elsewhere>" to correct the tip of the checked out branch;
- As another step to support large files better, "git add" stores large files directly into a new packfile without having to hold everything in-core at once; and
- "Signed commit" support, that lets a commit object record a GPG signature on it.
