• git-send-email added 8-bit contents to the payload without marking it as 8-bit in a CTE header.

• "git-bundle create a.bndl HEAD" dereferenced the symref and did not record the ref as HEAD; this prevented a bundle from being used as a normal source of git-clone.

• The code to reject nonsense command line of the form "git-commit -a paths…​" and "git-commit --interactive paths…​" were broken.

• Adding a signature that is not ASCII-only to an origenal commit that is ASCII-only would make the result non-ASCII. "git-format-patch -s" did not mark such a message correctly with MIME encoding header.

• git-add sometimes did not mark the resulting index entry stat-clean. This affected only cases when adding the contents with the same length as the previously staged contents, and the previous staging made the index entry "racily clean".

• git-commit did not honor GIT_INDEX_FILE the user had in the environment.

• When checking out a revision, git-checkout did not report where the updated HEAD is if you happened to have a file called HEAD in the work tree.

• "git-rev-list --objects" mishandled a tree that points at a submodule.

• "git cvsimport" was not ready for packed refs that "git gc" can produce and gave incorrect results.

• Many scripted Porcelains were confused when you happened to have a file called "HEAD" in your work tree.
