Updates since v2.21
-------------------
+Backward compatibility note
+
+ * The filter specification "--filter=sparse:path=<path>" used to
+ create a lazy/partial clone has been removed. Using a blob that is
+ part of the project as sparse specification is still supported with
+ the "--filter=sparse:oid=<blob>" option.
+
UI, Workflows & Features
* "git checkout --no-overlay" can be used to trigger a new mode of
repositories now; also the pathname hash-cache is created by
default to avoid making crappy deltas when repacking.
+ * "git branch new A...B" and "git checkout -b new A...B" have been
+ taught that in their contexts, the notation A...B means "the merge
+ base between these two commits", just like "git checkout A...B"
+ detaches HEAD at that commit.
+
+ * Update "git difftool" and "git mergetool" so that the combinations
+ of {diff,merge}.{tool,guitool} configuration variables serve as
+ fallback settings of each other in a sensible order.
+
+ * The "--dir-diff" mode of "git difftool" is not useful in "--no-index"
+ mode; they are now explicitly marked as mutually incompatible.
+
Performance, Internal Implementation, Development Support etc.

+ declaration.
* The script to aggregate perf result unconditionally depended on
libjson-perl even though it did not have to, which has been
* The internal implementation of "git rebase -i" has been updated to
avoid forking a separate "rebase--interactive" process.
+ * Allow DEP and ASLR for Windows build to for security hardening.
+
+ * Performance test framework has been broken and measured the version
+ of Git that happens to be on $PATH, not the specified one to
+ measure, for a while, which has been corrected.
+
+ * Optionally "make coccicheck" can feed multiple source files to
+ spatch, gaining performance while spending more memory.
+
+ * Attempt to use an abbreviated option in "git clone --recurs" is
+ responded by a request to disambiguate between --recursive and
+ --recurse-submodules, which is bad because these two are synonyms.
+ The parse-options API has been extended to define such synonyms
+ more easily and not produce an unnecessary failure.
+
+ * A pair of private functions in http.c that had names similar to
+ fread/fwrite did not return the number of elements, which was found
+ to be confusing.
+
+ * Update collision-detecting SHA-1 code to build properly on HP-UX.

Fixes since v2.21
-----------------
* On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
the upload-pack that runs on the other end that hangs up after
detecting an error could cause "git fetch" to die with a signal,
- which led to a flakey test. "git fetch" now ignores SIGPIPE during
+ which led to a flaky test. "git fetch" now ignores SIGPIPE during
the network portion of its operation (this is not a problem as we
check the return status from our write(2)s).

(merge b3223761c8 jk/server-info-rabbit-hole later to maint).
* The message given when "git commit -a <paths>" errors out has been
* When given a tag that points at a commit-ish, "git replace --graft"
failed to peel the tag before writing a replace ref, which did not
make sense because the old graft mechanism the feature wants to

This has been fixed.

conflicts are resolved in working tree *.h files but before the
resolved results are added to the index. This has been corrected.

gets stopped with a conflict and the user concluded the sequence
with "git commit". Attempt to fix it by cleaning up the state
files used by these commands in such a situation.
(merge 4a72486de9 pw/clean-sequencer-state-upon-final-commit later to maint).
+ * On a filesystem like HFS+, the names of the refs stored as filesystem
+ entities may become different from what the end-user expects, just
+ like files in the working tree get "renamed". Work around the
+ mismatch by paying attention to the core.precomposeUnicode
+ configuration.
+ (merge 8e712ef6fc en/unicode-in-refnames later to maint).
+
+ * The code to generate the multi-pack idx file was not prepared to
+ see too many packfiles and ran out of open file descriptor, which
+ has been corrected.
+
+ * To run tests for Git SVN, our scripts for CI used to install the
+ git-svn package (in the hope that it would bring in the right
+ dependencies). This has been updated to install the more direct
+ dependency, namely, libsvn-perl.
+ (merge db864306cf sg/ci-libsvn-perl later to maint).

+ * "git cvsexportcommit" running on msys did not expect cvsnt showed

+
+ * A prerequisite check in the test suite to see if a working jgit is
+ available was made more robust.
