Backward Compatibility Notes
----------------------------
* Historically, the "-m" (mainline) option can only be used for "git
cherry-pick" and "git revert" when working with a merge commit.
This version of Git no longer warns or errors out when working with
a single-parent commit, as long as the argument to the "-m" option
is 1 (i.e. it has only one parent, and the request is to pick or
revert relative to that first parent). Scripts that relied on the
behaviour may get broken with this change.

* "git instaweb" learned to drive http.server that comes with
"batteries included" Python installation (both Python2 & 3).
* A new encoding UTF-16LE-BOM has been invented to force encoding to
UTF-16 with BOM in little endian byte order, which cannot be directly
generated by using iconv.
* A new date format "--date=human" that morphs its output depending
on how far the time is from the current time has been introduced.
"--date=auto" can be used to use this new format when the output is
going to the pager or to the terminal and otherwise the default
format.

* Cocci rules have been updated to encourage use of strbuf_addbuf().
* "git rebase --merge" has been reimplemented by reusing the internal
machinery used for "git rebase -i".
* More code in "git bisect" has been rewritten in C.
* Instead of going through "git-rebase--am" scriptlet to use the "am"
backend, the built-in version of "git rebase" learned to drive the
"am" backend directly.
* The assumption to work on the single "in-core index" instance has
been reduced from the library-ish part of the codebase.
* The test lint learned to catch non-portable "sed" options.
* "git pack-objects" learned another algorithm to compute the set of
objects to send, that trades the resulting packfile off to save
traversal cost to favor small pushes.
* The travis CI scripts have been corrected to build Git with the
compiler(s) of our choice.
* "git submodule update" learned to abort early when core.worktree
for the submodule is not set correctly to prevent spreading damage.
* Test suite has been adjusted to run on Azure Pipeline.
* Running "Documentation/doc-diff x" from anywhere other than the
top-level of the working tree did not show the usage string
correctly, which has been fixed.
* Use of the sparse tool got easier to customize from the command
line to help developers.

* "git cat-file --batch" reported a dangling symbolic link by
mistake, when it wanted to report that a given name is ambiguous.
* Documentation around core.crlf has been updated.
(merge c9446f0504 jk/autocrlf-overrides-eol-doc later to maint).
* The documentation of "git commit-tree" said that the command
understands "--gpg-sign" in addition to "-S", but the command line
parser did not know about the longhand, which has been corrected.
* "git rebase -x $cmd" did not reject multi-line command, even though
the command is incapable of handling such a command. It now is
rejected upfront.

* Output from "git help" was not correctly aligned, which has been
fixed.
(merge 6195a76da4 nd/help-align-command-desc later to maint).
* The "git submodule summary" subcommand showed shortened commit
object names by mechanically truncating them at 7-hexdigit, which
has been improved to let "rev-parse --short" scale the length of
the abbreviation with the size of the repository.
(merge 0586a438f6 sh/submodule-summary-abbrev-fix later to maint).
* The way the OSX build jobs updates its build environment used the
"--quiet" option to "brew update" command, but it wasn't all that
quiet to be useful. The use of the option has been replaced with
an explicit redirection to the /dev/null (which incidentally would
have worked around a breakage by recent updates to homebrew, which
has fixed itself already).

* "git --work-tree=$there --git-dir=$here describe --dirty" did not
work correctly as it did not pay attention to the location of the

corrected.
