+Git v2.4.2 Release Notes
+========================
+
+Fixes since v2.4.1
+------------------
+
+ * "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" fails 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 to /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).
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.
SYNOPSIS
--------
[verse]
-'git hash-object' [-t <type>] [-w] [--path=<file>|--no-filters] [--stdin] [--] <file>...
+'git hash-object' [-t <type>] [-w] [--path=<file>|--no-filters] [--stdin [--literally]] [--] <file>...
'git hash-object' [-t <type>] [-w] --stdin-paths [--no-filters] < <list-of-paths>
DESCRIPTION
Hash the contents as is, ignoring any input filter that would
have been chosen by the attributes mechanism, including the end-of-line
conversion. If the file is read from standard input then this
- is always implied, unless the --path option is given.
+ is always implied, unless the `--path` option is given.
+
+--literally::
+ Allow `--stdin` to hash any garbage into a loose object which might not
+ otherwise pass standard object parsing or git-fsck checks. Useful for
+ stress-testing Git itself or reproducing characteristics of corrupt or
+ bogus objects encountered in the wild.
