Git 2.7.0 RC0 发布，Git 2.7.0 更新内容如下：

UI, Workflows & Features

 * "git remote" learned "get-url" subcommand to show the URL for a
   given remote name used for fetching and pushing.

 * There was no way to defeat a configured rebase.autostash variable
   from the command line, as "git rebase --no-autostash" was missing.

 * "git log --date=local" used to only show the normal (default)
   format in the local timezone.  The command learned to take 'local'
   as an instruction to use the local timezone with other formats,

 * The refs used during a "git bisect" session is now per-worktree so
   that independent bisect sessions can be done in different worktrees
   created with "git worktree add".

 * Users who are too busy to type three extra keystrokes to ask for
   "git stash show -p" can now set stash.showPatch configuration
   varible to true to always see the actual patch, not just the list
   of paths affected with feel for the extent of damage via diffstat.

 * "quiltimport" allows to specify the series file by honoring the
   $QUILT_SERIES environment and also --series command line option.

 * The use of 'good/bad' in "git bisect" made it confusing to use when
   hunting for a state change that is not a regression (e.g. bugfix).
   The command learned 'old/new' and then allows the end user to
   say e.g. "bisect start --term-old=fast --term-new=slow" to find a
   performance regression.

 * "git interpret-trailers" can now run outside of a Git repository.

 * "git p4" learned to reencode the pathname it uses to communicate
   with the p4 depot with a new option.

 * Give progress meter to "git filter-branch".

 * Allow a later "!/abc/def" to override an earlier "/abc" that
   appears in the same .gitignore file to make it easier to express
   "everything in /abc directory is ignored, except for ...".

 * Teach "git p4" to send large blobs outside the repository by
   talking to Git LFS.

 * Prepare for Git on-disk repository representation to undergo
   backward incompatible changes by introducing a new repository
   format version "1", with an extension mechanism.

 * "git worktree" learned a "list" subcommand.

 * "git clone --dissociate" learned that it can be used even when
   "--reference" was not used at the same time.

 * "git blame" learnt to take "--first-parent" and "--reverse" at the
   same time when it makes sense.

 * "git checkout" did not follow the usual "--[no-]progress"
   convention and implemented only "--quiet" that is essentially
   a superset of "--no-progress".  Extend the command to support the
   usual "--[no-]progress".

 * The semantics of tranfer.hideRefs configuration variable have been
   extended to work better with the ref "namespace" feature that lets
   you throw unrelated bunches of repositories in a single physical
   repository and virtually serve them as separate ones.

 * send-email config variables whose values are pathnames now go
   through the ~username/ expansion.

 * bash completion learnt to TAB-complete recipient addresses given
   to send-email.

 * The credential-cache daemon can be told to ignore SIGHUP to work
   around issue when running Git from inside emacs.


Performance, Internal Implementation, Development Support etc.

 * The infrastructure to rewrite "git submodule" in C is being built
   incrementally.  Let's polish these early parts well enough and make
   them graduate to 'next' and 'master', so that the more involved
   follow-up can start cooking on a solid ground.

 * Some features from "git tag -l" and "git branch -l" have been made
   available to "git for-each-ref" so that eventually the unified
   implementation can be shared across all three.  The version merged
   to the 'master' branch earlier had a performance regression in "tag
   --contains", which has since been corrected.

 * Because "test_when_finished" in our test framework queues the
   clean-up tasks to be done in a shell variable, it should not be
   used inside a subshell.  Add a mechanism to allow 'bash' to catch
   such uses, and fix the ones that were found.

 * The debugging infrastructure for pkt-line based communication has
   been improved to mark the side-band communication specifically.
   (merge fd89433 jk/async-pkt-line later to maint).

 * Update "git branch" that list existing branches, using the
   ref-filter API that is shared with "git tag" and "git
   for-each-ref".

 * The test for various line-ending conversions has been enhanced.

 * A few test scripts around "git p4" have been improved for
   portability.

 * Many allocations that is manually counted (correctly) that are
   followed by strcpy/sprintf have been replaced with a less error
   prone constructs such as xstrfmt.

 * The internal stripspace() function has been moved to where it
   logically belongs to, i.e. strbuf API, and the command line parser
   of "git stripspace" has been updated to use the parse_options API.

 * "git am" used to spawn "git mailinfo" via run_command() API once
   per each patch, but learned to make a direct call to mailinfo()
   instead.

 * The implementation of "git mailinfo" was refactored so that a
   mailinfo() function can be directly called from inside a process.

 * With a "debug" helper, debugging of a single "git" invocation in
   our test scripts has become a lot easier.

 * The "configure" script did not test for -lpthread correctly, which
   upset some linkers.

 * Cross completed task off of subtree project's todo list.

 * Test cleanups for the subtree project.

 * Clean up style in an ancient test t9300.

 * Work around some test flakiness with p4d.

 * Fsck did not correctly detect a NUL-truncated header in a tag.

 * Use a safer behavior when we hit errors verifying remote certificates.

 * Speed up filter-branch for cases where we only care about rewriting
   commits, not tree data.

 * The parse-options API has been updated to make "-h" command line
   option work more consistently in all commands.

 * "git svn rebase/mkdirs" got optimized by keeping track of empty
   directories better.

 * Fix some racy client/server tests by treating SIGPIPE the same as a
   normal non-zero exit.

 * The necessary infrastructure to build topics using the free Travis
   CI has been added. Developers forking from this topic (and enabling
   Travis) can do their own builds, and we can turn on auto-builds for
   git/git (including build-status for pull requests that people
   open).
