* Many 'linkgit:<git documentation page>' references were broken,
which are all fixed with this.
+ * "git describe --contains" often made a hard-to-justify choice of
+ tag to give name to a given commit, because it tried to come up
+ with a name with smallest number of hops from a tag, causing an old
+ commit whose close descendant that is recently tagged were not
+ described with respect to an old tag but with a newer tag. It did
+ not help that its computation of "hop" count was further tweaked to
+ penalize being on a side branch of a merge. The logic has been
+ updated to favor using the tag with the oldest tagger date, which
+ is a lot easier to explain to the end users: "We describe a commit
+ in terms of the (chronologically) oldest tag that contains the
+ commit."
+
+ * Running tests with '-x' option to trace the individual command
+ executions is a useful way to debug test scripts, but some tests
+ that capture the standard error stream and check what the command
+ said can be broken with the trace output mixed in. When running
+ our tests under "bash", however, we can redirect the trace output
+ to another file descriptor to keep the standard error of programs
+ being tested intact.
+
+ * "http.cookieFile" configuration variable clearly wants a pathname,
+ but we forgot to treat it as such by e.g. applying tilde expansion.
+
+ * When de-initialising all submodules, "git submodule deinit" gave a
+ faulty recommendation to use "git submodule deinit .", which would
+ result in a strange error message in a pathological corner case.
+ This has been corrected to suggest "submodule deinit --all" instead.
+
+ * Many commands normalize command line arguments from NFD to NFC
+ variant of UTF-8 on OSX, but commands in the "diff" family did
+ not, causing "git diff $path" to complain that no such path is
+ known to Git. They have been taught to do the normalization.
+
+ * A couple of bugs around core.autocrlf have been fixed.
+
+ * "git difftool" learned to handle unmerged paths correctly in
+ dir-diff mode.
+
+ * The "are we talking with TTY, doing an interactive session?"
+ detection has been updated to work better for "Git for Windows".
