+Git v2.6.4 Release Notes
+========================
+
+Fixes since v2.6.3
+------------------
+
+ * The "configure" script did not test for -lpthread correctly, which
+ upset some linkers.
+
+ * Add support for talking http/https over socks proxy.
+
+ * Portability fix for Windows, which may rewrite $SHELL variable using
+ non-POSIX paths.
+
+ * We now consistently allow all hooks to ignore their standard input,
+ rather than having git complain of SIGPIPE.
+
+ * Fix shell quoting in contrib script.
+
+ * Test portability fix for a topic in v2.6.1.
+
+ * Allow tilde-expansion in some http config variables.
+
+ * Give a useful special case "diff/show --word-diff-regex=." as an
+ example in the documentation.
+
+ * Fix for a corner case in filter-branch.
+
+ * Make git-p4 work on a detached head.
+
+ * Documentation clarification for "check-ignore" without "--verbose".
+
+ * Just like the working tree is cleaned up when the user cancelled
+ submission in P4Submit.applyCommit(), clean up the mess if "p4
+ submit" fails.
+
+ * Having a leftover .idx file without corresponding .pack file in
+ the repository hurts performance; "git gc" learned to prune them.
+
+ * The code to prepare the working tree side of temporary directory
+ for the "dir-diff" feature forgot that symbolic links need not be
+ copied (or symlinked) to the temporary area, as the code already
+ special cases and overwrites them. Besides, it was wrong to try
+ computing the object name of the target of symbolic link, which may
+ not even exist or may be a directory.
+
+ * There was no way to defeat a configured rebase.autostash variable
+ from the command line, as "git rebase --no-autostash" was missing.
+
+ * Allow "git interpret-trailers" to run outside of a Git repository.
+
+ * Produce correct "dirty" marker for shell prompts, even when we
+ are on an orphan or an unborn branch.
+
+ * Some corner cases have been fixed in string-matching done in "git
+ status".
+
+ * Apple's common crypto implementation of SHA1_Update() does not take
+ more than 4GB at a time, and we now have a compile-time workaround
+ for it.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.6.5 Release Notes
+========================
+
+Fixes since v2.6.4
+------------------
+
+ * 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.
+
+ * Update "git subtree" (in contrib/) so that it can take whitespaces
+ in the pathnames, not only in the in-tree pathname but the name of
+ the directory that the repository is in.
+
+ * Cosmetic improvement to lock-file error messages.
+
+ * mark_tree_uninteresting() has code to handle the case where it gets
+ passed a NULL pointer in its 'tree' parameter, but the function had
+ 'object = &tree->object' assignment before checking if tree is
+ NULL. This gives a compiler an excuse to declare that tree will
+ never be NULL and apply a wrong optimization. Avoid it.
+
+ * The helper used to iterate over loose object directories to prune
+ stale objects did not closedir() immediately when it is done with a
+ directory--a callback such as the one used for "git prune" may want
+ to do rmdir(), but it would fail on open directory on platforms
+ such as WinXP.
+
+ * "git p4" used to import Perforce CLs that touch only paths outside
+ the client spec as empty commits. It has been corrected to ignore
+ them instead, with a new configuration git-p4.keepEmptyCommits as a
+ backward compatibility knob.
+
+ * The exit code of git-fsck did not reflect some types of errors
+ found in packed objects, which has been corrected.
+
+ * The completion script (in contrib/) used to list "git column"
+ (which is not an end-user facing command) as one of the choices
+
+ * Improve error reporting when SMTP TLS fails.
+
+ * When getpwuid() on the system returned NULL (e.g. the user is not
+ in the /etc/passwd file or other uid-to-name mappings), the
+ codepath to find who the user is to record it in the reflog barfed
+ and died. Loosen the check in this codepath, which already accepts
+ questionable ident string (e.g. host part of the e-mail address is
+ obviously bogus), and in general when we operate fmt_ident() function
+ in non-strict mode.
+
+ * "git symbolic-ref" forgot to report a failure with its exit status.
+
+ * History traversal with "git log --source" that starts with an
+ annotated tag failed to report the tag as "source", due to an
+ old regression in the command line parser back in v2.2 days.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+
+ * Some "git notes" operations, e.g. "git log --notes=<note>", should

+ $GIT_DIR, 2015-06-26) attempted to work around a glitch in alias
+ handling by overwriting GIT_WORK_TREE environment variable to
+ affect subprocesses when set_git_work_tree() gets called, which
+ resulted in a rather unpleasant regression to "clone" and "init".
+ Try to address the same issue by always restoring the environment
+ and respawning the real underlying command when handling alias.
+
+ * The low-level code that is used to create symbolic references has
+ been updated to share more code with the code that deals with
+ normal references.
+
+ * strbuf_getline() and friends have been redefined to make it easier
+ to identify which callsite of (new) strbuf_getline_lf() should
+ allow and silently ignore carriage-return at the end of the line to
+ help users on DOSsy systems.
+
+ * "git shortlog" used to accumulate various pieces of information
+ regardless of what was asked to be shown in the final output. It
+ has been optimized by noticing what need not to be collected
+ (e.g. there is no need to collect the log messages when showing
+ only the number of changes).
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.7
+----------------
+
+Unless otherwise noted, all the fixes since v2.7 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * An earlier change in 2.5.x-era broke users' hooks and aliases by
+ exporting GIT_WORK_TREE to point at the root of the working tree,
+ interfering when they tried to use a different working tree without
+ setting GIT_WORK_TREE environment themselves.
+ (merge df1e6ea nd/stop-setenv-work-tree later to maint).
+
+ * The "exclude_list" structure has the usual "alloc, nr" pair of
+ fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot
+ to reset 'alloc' to 0 when it cleared 'nr' to discard the managed
+ array.
+ (merge 2653a8c nd/dir-exclude-cleanup later to maint).
+
+ * Paths that have been told the index about with "add -N" are not
+ quite yet in the index, but a few commands behaved as if they
+ already are in a harmful way.
+ (merge 4d55200 nd/ita-cleanup later to maint).
+
+ * "git send-email" was confused by escaped quotes stored in the alias
+ files saved by "mutt", which has been corrected.
+ (merge 2c510f2 ew/send-email-mutt-alias-fix later to maint).
+
+ * A few unportable C construct have been spotted by clang compiler
+ and have been fixed.
+ (merge a0df2e5 jk/clang-pedantic later to maint).
+
+ * The documentation has been updated to hint the connection between
+ the '--signoff' option and DCO.
+ (merge b2c150d dw/signoff-doc later to maint).
+
+ * "git reflog" incorrectly assumed that all objects that used to be
+ at the tip of a ref must be commits, which caused it to segfault.
+ (merge aecad37 dk/reflog-walk-with-non-commit later to maint).
+
+ * The ignore mechanism saw a few regressions around untracked file
+ listing and sparse checkout selection areas in 2.7.0; the change
+ that is responsible for the regression has been reverted.
+ (merge 8c72236 nd/exclusion-regression-fix later to maint).
+
+ * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
+ (e.g. COMMIT_EDITMSG) that is meant to be left after the command is
+ done. This however did not work well if the repository is set to
+ be shared with core.sharedRepository and the umask of the previous
+ user is tighter. They have been made to work better by calling
+ unlink(2) and retrying after fopen(3) fails with EPERM.
+ (merge ea56518 js/fopen-harder later to maint).
+
+ * Asking gitweb for a nonexistent commit left a warning in the server
+ log.
+
+ Somebody may want to follow this up with an additional test, perhaps?
+ IIRC, we do test that no Perl warnings are given to the server log,
+ so this should have been caught if our test coverage were good.
+ (merge a9eb90a ho/gitweb-squelch-undef-warning later to maint).
+
+ * "git rebase", unlike all other callers of "gc --auto", did not
+ ignore the exit code from "gc --auto".
+ (merge 8c24f5b jk/ok-to-fail-gc-auto-in-rebase later to maint).
+
+ * Many codepaths that run "gc --auto" before exiting kept packfiles
+ mapped and left the file descriptors to them open, which was not
+ friendly to systems that cannot remove files that are open. They
+ now close the packs before doing so.
+ (merge d562102 js/close-packs-before-gc later to maint).
+
+ * A recent optimization to filter-branch in v2.7.0 introduced a
+ regression when --prune-empty filter is used, which has been
+ corrected.
+ (merge 1dc413e jk/filter-branch-no-index later to maint).
+
+ * The description for SANITY prerequisite the test suite uses has
+ been clarified both in the comment and in the implementation.
+ (merge 719c3da jk/sanity later to maint).
+
+ * "git tag" started listing a tag "foo" as "tags/foo" when a branch
+ named "foo" exists in the same repository; remove this unnecessary
+ disambiguation, which is a regression introduced in v2.7.0.
+ (merge 0571979 jk/list-tag-2.7-regression later to maint).
+
+ * The way "git svn" uses auth parameter was broken by Subversion
+ 1.9.0 and later.
+ (merge 0b66415 ew/svn-1.9.0-auth later to maint).
+
+ * Other minor clean-ups and documentation updates
+ (merge 99487cf ss/user-manual later to maint).
+ (merge e914ef0 ew/for-each-ref-doc later to maint).
+ (merge 36fc7d8 sg/t6050-failing-editor-test-fix later to maint).
+ (merge 60253a6 ss/clone-depth-single-doc later to maint).
