- The usual git diff, when seeing a file turning into a directory, showed a patchset to remove the file and create all files in the directory, but git diff --no-index simply refused to work. Also, when asked to compare a file and a directory, imitate POSIX diff and compare the file with the file with the same name in the directory, instead of refusing to run.
- The default $HOME/.gitconfig file created upon git config --global that edits it had incorrectly spelled user.name and user.email entries in it.
- git commit --date=now or anything that relies on approxidate lost the daylight-saving-time offset.
- git cat-file bl $blob failed to barf even though there is no object type that is "bl".
- Teach the codepaths that read .gitignore and .gitattributes files that these files encoded in UTF-8 may have UTF-8 BOM marker at the beginning; this makes it in line with what we do for configuration files already.
- Access to objects in repositories that borrow from another one on a slow NFS server unnecessarily got more expensive due to recent code becoming more cautious in a naive way not to lose objects to pruning.
- We avoid setting core.worktree when the repository location is the .git directory directly at the top level of the working tree, but the code misdetected the case in which the working tree is at the root level of the filesystem (which arguably is a silly thing to do, but still valid).
- git rev-list --objects $old --not --all to see if everything that is reachable from $old is already connected to the existing refs was very inefficient.
- hash-object --literally introduced in v2.2 was not prepared to take a really long object type name.
- git rebase --quiet was not quite quiet when there is nothing to do.
- The completion for log --decorate= parameter value was incorrect.
- filter-branch corrupted commit log message that ends with an incomplete line on platforms with some sed implementations that munge such a line. Work it around by avoiding to use sed.
- git daemon failed to build from the source under NO_IPV6 configuration (regression in 2.4).
- git stash pop/apply forgot to make sure that not just the working tree is clean but also the index is clean. The latter is important as a stash application can conflict and the index will be used for conflict resolution.
- We have prepended $GIT_EXEC_PATH and the path git is installed in (typically /usr/bin) to $PATH when invoking subprograms and hooks for almost eternity, but the original use case the latter tried to support was semi-bogus (i.e. install git as /opt/foo/git and run it without having /opt/foo on $PATH), and more importantly it has become less and less relevant as Git grew more mainstream (i.e. the users would want to have it on their $PATH). Stop prepending the path in which git is installed to users' $PATH, as that would interfere the command search order people depend on (e.g. they may not like versions of programs that are unrelated to Git in /usr/bin and want to override them by having different ones in /usr/local/bin and have the latter directory earlier in their $PATH).
Git hopefully continues to improve.
Have fun.
