operation learned to show the progress meter.

piece of memory while writing each index entry out. This has been
optimized.
+ * Platforms that ship with a separate sha1 with collision detection
+ library can link to it instead of using the copy we ship as part of
+ our source tree.
+
+ * Code around "notes" have been cleaned up.
+ (merge 3964281524 mh/notes-cleanup later to maint).
+
+ * The long-standing rule that an in-core lockfile instance, once it
+ is used, must not be freed, has been lifted and the lockfile and
+ tempfile APIs have been updated to reduce the chance of programming
+ errors.
+
+ * Our hashmap implementation in hashmap.[ch] is not thread-safe when
+ adding a new item needs to expand the hashtable by rehashing; add
+ an API to disable the automatic rehashing to work it around.
+
+ * Many of our programs consider that it is OK to release dynamic
+ storage that is used throughout the life of the program by simply
+ exiting, but this makes it harder to leak detection tools to avoid
+ reporting false positives. Plug many existing leaks and introduce
+ a mechanism for developers to mark that the region of memory
+ pointed by a pointer is not lost/leaking to help these tools.
+
+ * As "git commit" to conclude a conflicted "git merge" honors the
+ commit-msg hook, "git merge" that records a merge commit that
+ cleanly auto-merges should, but it didn't.
+
+ * The codepath for "git merge-recursive" has been cleaned up.
+
+ * Many leaks of strbuf have been fixed.
+
+ * "git imap-send" has our own implementation of the protocol and also
+ can use more recent libCurl with the imap protocol support. Update
+ the latter so that it can use the credential subsystem, and then
+ make it the default option to use, so that we can eventually
+ deprecate and remove the former.
+
+ * "make style" runs git-clang-format to help developers by pointing
+ out coding style issues.
+
+ * A test to demonstrate "git mv" failing to adjust nested submodules
+ has been added.
+ (merge c514167df2 hv/mv-nested-submodules-test later to maint).
+
+ * On Cygwin, "ulimit -s" does not report failure but it does not work
+ at all, which causes an unexpected success of some tests that
+ expect failures under a limited stack situation. This has been
+ fixed.

+ * "git gc" and friends when multiple worktrees are used off of a
+ single repository did not consider the index and per-worktree refs
+ of other worktrees as the root for reachability traversal, making
+ objects that are in use only in other worktrees to be subject to
+ garbage collection.
+
+ * A regression to "gitk --bisect" by a recent update has been fixed.
+ (merge 1d0538e486 mh/packed-ref-store-prep later to maint).
+
+ * "git -c submodule.recurse=yes pull" did not work as if the
+ "--recurse-submodules" option was given from the command line.
+ This has been corrected.
+
+ * Unlike "git commit-tree < file", "git commit-tree -F file" did not
+ pass the contents of the file verbatim and instead completed an
+ incomplete line at the end, if exists. The latter has been updated
+ to match the behaviour of the former.
+ (merge c818e74332 rk/commit-tree-make-F-verbatim later to maint).
+
+ * Many codepaths did not diagnose write failures correctly when disks
+ go full, due to their misuse of write_in_full() helper function,
+ which have been corrected.
+ (merge f48ecd38cb jk/write-in-full-fix later to maint).
+
+ * "git help co" now says "co is aliased to ...", not "git co is".
+ (merge b3a8076e0d ks/help-alias-label later to maint).
+
+ * "git archive", especially when used with pathspec, stored an empty
+ directory in its output, even though Git itself never does so.
+ This has been fixed.
+ (merge 4318094047 rs/archive-excluded-directory later to maint).
+
+ * API error-proofing which happens to also squelch warnings from GCC.
+ (merge c788c54cde tg/refs-allowed-flags later to maint).
+
+ * The explanation of the cut-line in the commit log editor has been
+ slightly tweaked.
+ (merge 8c4b1a3593 ks/commit-do-not-touch-cut-line later to maint).
+
+ * "git gc" tries to avoid running two instances at the same time by
+ reading and writing pid/host from and to a lock file; it used to
+ use an incorrect fscanf() format when reading, which has been
+ corrected.
+ (merge afe2fab72c aw/gc-lockfile-fscanf-fix later to maint).
+
+ * The scripts to drive TravisCI has been reorganized and then an
+ optimization to avoid spending cycles on a branch whose tip is
+ tagged has been implemented.
+ (merge 8376eb4a8f ls/travis-scriptify later to maint).
+
+ * The test linter has been taught that we do not like "echo -e".
+ (merge 1a6d46895d tb/test-lint-echo-e later to maint).
+
+ * Code cmp.std.c nitpick.
+ (merge ac7da78ede mh/for-each-string-list-item-empty-fix later to maint).

+ alternate object stores overrun the end of the string.
+ (merge f0f7bebef7 jk/info-alternates-fix later to maint).
