* "git p4" learned four new hooks and also "--no-verify" option to

bypass them (and the existing "p4-pre-submit" hook).

* "git pull" shares many options with underlying "git fetch", but

some of them were not documented and some of those that would make

sense to pass down were not passed down.

* "git rebase" learned the "--no-gpg-sign" option to countermand

commit.gpgSign the user may have.

* The output from "git format-patch" uses RFC 2047 encoding for

non-ASCII letters on From: and Subject: headers, so that it can

directly be fed to e-mail programs. A new option has been added

to produce these headers in raw.

* "git log" learned "--show-pulls" that helps pathspec limited

history views; a merge commit that takes the whole change from a

side branch, which is normally omitted from the output, is shown

in addition to the commits that introduce real changes.

* The interactive input from various codepaths are consolidated and

any prompt possibly issued earlier are fflush()ed before we read.

* Allow "git rebase" to reapply all local commits, even if the may be

already in the upstream, without checking first.

* The 'pack.useSparse' configuration variable now defaults to 'true',

enabling an optimization that has been experimental since Git 2.21.

* Enable tests that require GnuPG on Windows.

* Minor test usability improvement.

* Trace2 enhancement to allow logging of the environment variables.

* Test clean-up continues.

* Perf-test update.

* A Windows-specific test element has been made more robust against

misuse from both user's environment and programmer's errors.

* The import-tars importer (in contrib/fast-import/) used to create

phony files at the top-level of the repository when the archive

contains global PAX headers, which made its own logic to detect and

omit the common leading directory ineffective, which has been

corrected.

(merge c839fcff65 js/import-tars-do-not-make-phony-files-from-pax-headers later to maint).

* Simplify the commit ancestry connectedness check in a partial clone

repository in which "promised" objects are assumed to be obtainable

lazily on-demand from promisor remote repositories.

(merge 2b98478c6f jt/connectivity-check-optim-in-partial-clone later to maint).

* The server-end of the v2 protocol to serve "git clone" and "git

fetch" was not prepared to see a delim packets at unexpected

places, which led to a crash.

(merge cacae4329f jk/harden-protocol-v2-delim-handling later to maint).

* When fed a midx that records no objects, some codepaths tried to

loop from 0 through (num_objects-1), which, due to integer

arithmetic wrapping around, made it nonsense operation with out of

bounds array accesses. The code has been corrected to reject such

an midx file.

(merge 796d61cdc0 dr/midx-avoid-int-underflow later to maint).

* Utitiles run via the run_command() API were not spawned correctly

on Cygwin, when the paths to them are given as a full path with

backslashes.

(merge 05ac8582bc ak/run-command-on-cygwin-fix later to maint).

* "git pull --rebase" tried to run a rebase even after noticing that

the pull results in a fast-forward and no rebase is needed nor

sensible, for the past few years due to a mistake nobody noticed.

(merge fbae70ddc6 en/pull-do-not-rebase-after-fast-forwarding later to maint).

* "git rebase" with the merge backend did not work well when the

rebase.abbreviateCommands configuration was set.

(merge de9f1d3ef4 ag/rebase-merge-allow-ff-under-abbrev-command later to maint).

* The logic to auto-follow tags by "git clone --single-branch" was

not careful to avoid lazy-fetching unnecessary tags, which has been

corrected.

(merge 167a575e2d jk/use-quick-lookup-in-clone-for-tag-following later to maint).

* "git rebase -i" did not leave the reflog entries correctly.

(merge 1f6965f994 en/sequencer-reflog-action later to maint).

* The more aggressive updates to remote-tracking branches we had for

the past 7 years or so were not reflected in the documentation,

which has been corrected.

(merge a44088435c pb/pull-fetch-doc later to maint).

* We've left the command line parsing of "git log :/a/b/" broken for

about a full year without anybody noticing, which has been

corrected.

(merge 0220461071 jc/missing-ref-store-fix later to maint).

* Misc fixes for Windows.

(merge 3efc128cd5 js/mingw-fixes later to maint).

* "git rebase" (again) learns to honor "--no-keep-empty", which lets

the user to discard commits that are empty from the beginning (as

opposed to the ones that become empty because of rebasing). The

interactive rebase also marks commits that are empty in the todo.

(merge 50ed76148a en/rebase-no-keep-empty later to maint).

* Parsing the host part out of URL for the credential helper has been corrected.
