+ our side originally had.
* "git filter-branch" learned to use a different exit code to allow
the callers to tell the case where there was no new commits to
have been replaced with a stub that errors out and tells the user
there are replacements.

contents to the specified encoding when checking out to the working
tree (and the other way around when checking in).

custom completion file for "git $command" where $command is a

+ newer version of bash-completion.
+
+ * "git send-email" can sometimes offer confirmation dialog "Send this
+ email?" with choices 'Yes', 'No', 'Quit', and 'All'. A new action
+ 'Edit' has been added to this dialog's choice.
+
+ * With merge.renames configuration set to false, the recursive merge
+ strategy can be told not to spend cycles trying to find renamed
+ paths and merge them accordingly.
+
+ * "git status" learned to honor a new status.renames configuration to
+ skip rename detection, which could be useful for those who want to
+ do so without disabling the default rename detection done by the
+ "git diff" command.
+
+ * Command line completion (in contrib/) learned to complete pathnames
+ for various commands better.
+
+ * "git blame" learns to unhighlight uninteresting metadata from the
+ originating commit on lines that are the same as the previous one,
+ and also paint lines in different colors depending on the age of
+ the commit.
+
+ * Transfer protocol v2 learned to support the partial clone.
+
+ * When a short hexadecimal string is used to name an object but there
+ are multiple objects that share the string as the prefix of their
+ names, the code lists these ambiguous candidates in a help message.
+ These object names are now sorted according to their types for
+ easier eyeballing.
+
+ * "git fetch $there $refspec" that talks over protocol v2 can take
+ advantage of server-side ref filtering; the code has been extended
+ so that this mechanism triggers also when fetching with configured
+ refspec.

+ from the other side; instead, just let cURL library to advertise
+ and negotiate the best one.

- z/b and z/c, it is likely that x/d added in the meantime would also
- want to move to z/d by taking the hint that the entire directory

* "git pack-objects" needs to allocate tons of "struct object_entry"
while doing its work, and shrinking its size helps the performance
quite a bit.
+ * The implementation of "git rebase -i --root" has been updated to use
+ the sequencer machinery more.
+
+ * Developer support update, by using BUG() macro instead of die() to
+ mark codepaths that should not happen more clearly.
+
+ * Developer support. Use newer GCC on one of the builds done at
+ TravisCI.org to get more warnings and errors diagnosed.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * By code restructuring of submodule merge in merge-recursive,
+ informational messages from the codepath are now given using the
+ same mechanism as other output, and honor the merge.verbosity
+ configuration. The code also learned to give a few new messages
+ when a submodule three-way merge resolves cleanly when one side
+ records a descendant of the commit chosen by the other side.
+
+ * Avoid unchecked snprintf() to make future code auditing easier.
+ (merge ac4896f007 jk/snprintf-truncation later to maint).
+
+ * Many tests hardcode the raw object names, which would change once
+ we migrate away from SHA-1. While some of them must test against
+ exact object names, most of them do not have to use hardcoded
+ constants in the test. The latter kind of tests have been updated
+ to test the moral equivalent of the original without hardcoding the
+ actual object names.
+
+ * The list of commands with their various attributes were spread
+ across a few places in the build procedure, but it now is getting a
+ bit more consolidated to allow more automation.
+
+ * Quite a many tests assumed that newly created refs are made as
+ loose refs using the files backend, which have been updated to use
+ proper plumbing like rev-parse and update-ref, to avoid breakage
+ once we start using different ref backends.

+ * Code clean-up to adjust to a more recent lockfile API convention that
+ allows lockfile instances kept on the stack.
+ (merge 0fa5a2ed8d ma/lockfile-cleanup later to maint).
+
+ * the_repository->index is not a allocated piece of memory but
+ repo_clear() indiscriminately attempted to free(3) it, which has
+ been corrected.

+ * Code clean-up to avoid non-standard-conformant pointer arithmetic.

+ * Code clean-up to turn history traversal more robust in a
+ semi-corrupt repository.

+
+ * "git update-ref A B" is supposed to ensure that ref A does not yet
+ exist when B is a NULL OID, but this check was not done correctly
+ for pseudo-refs outside refs/ hierarchy, e.g. MERGE_HEAD.
+
+ * "git submodule update" and "git submodule add" supported the
+ "--reference" option to borrow objects from a neighbouring local
+ repository like "git clone" does, but lacked the more recent
+ invention "--dissociate". Also "git submodule add" has been taught
+ to take the "--progress" option.
+ (merge a0ef29341a cf/submodule-progress-dissociate later to maint).
+
+ * Update credential-netrc helper (in contrib/) to allow customizing
+ the GPG used to decrypt the encrypted .netrc file.
+ (merge 786ef50a23 lm/credential-netrc later to maint).
+
+ * "git submodule update" attempts two different kinds of "git fetch"
+ against the upstream repository to grab a commit bound at the
+ submodule's path, but it incorrectly gave up if the first kind
+ (i.e. a normal fetch) failed, making the second "last resort" one
+ (i.e. fetching an exact commit object by object name) ineffective.
+ This has been corrected.
+ (merge e30d833671 sb/submodule-update-try-harder later to maint).
+
+ * Error behaviour of "git grep" when it cannot read the index was
+ inconsistent with other commands that uses the index, which has
+ been corrected to error out early.
+ (merge b2aa84c789 sb/grep-die-on-unreadable-index later to maint).
+
+ * We used to call regfree() after regcomp() failed in some codepaths,
+ which have been corrected.
+ (merge 17154b1576 ma/regex-no-regfree-after-comp-fail later to maint).
+
+ * The import-tars script (in contrib/) has been taught to handle
+ tarballs with overly long paths that use PAX extended headers.
+ (merge 12ecea46e3 pa/import-tars-long-names later to maint).
+
+ * "git rev-parse Y..." etc. misbehaved when given endpoints were
+ not committishes.
+ (merge 0ed556d38f en/rev-parse-invalid-range later to maint).
+
+ * "git pull --recurse-submodules --rebase", when the submodule
+ repository's history did not have anything common between ours and
+ the upstream's, failed to execute. We need to fetch from them to
+ continue even in such a case.
+ (merge 4d36f88be7 jt/submodule-pull-recurse-rebase later to maint).
+
+ * "git remote update" can take both a single remote nickname and a
+ nickname for remote groups, but only one of them was documented.
+ (merge a97447a42a nd/remote-update-doc later to maint).
+
+ * "index-pack --strict" has been taught to make sure that it runs the
+ final object integrity checks after making the freshly indexed
+ packfile available to itself.
+ (merge 3737746120 jk/index-pack-maint later to maint).
+
+ * Make zlib inflate codepath more robust against versions of zlib
+ that clobber unused portion of outbuf.
+ (merge b611396e97 jl/zlib-restore-nul-termination later to maint).
+
+ * Fix old merge glitch in Documentation during v2.13-rc0 era.
+ (merge 28cb06020b mw/doc-merge-enumfix later to maint).
+
+ * The code to read compressed bitmap was not careful to avoid reading
+ past the end of the file, which has been corrected.
+ (merge 1140bf01ec jk/ewah-bounds-check later to maint).
+
+ * "make NO_ICONV=NoThanks" did not override NEEDS_LIBICONV
+ (i.e. linkage of -lintl, -liconv, etc. that are platform-specific
+ tweaks), which has been corrected.
+ (merge fdb1fbbc7d es/make-no-iconv later to maint).
