Foreign interfaces, subsystems and ports.
+ * Cygwin port has been updated for more recent Cygwin 1.7.
+
* "git rebase -i" now honors --strategy and -X options.
* Git-gui has been updated to its 0.18.0 version.
* git-remote-mw (in contrib/) hints users to check the certificate,
when https:// connection failed.

+
UI, Workflows & Features
+ * Sample "post-receive-email" hook script got an enhanced replacement
+ "multimail" (in contrib/).
+
+ * Also in contrib/ is a new "contacts" script that runs "git blame"
+ to find out the people who may be interested in a set of changes.
+
+ * "git clean" command learned an interactive mode.
+
+ * The "--head" option to "git show-ref" was only to add "HEAD" to the
+ list of candidate refs to be filtered by the usual rules
+ (e.g. "--heads" that only show refs under refs/heads). The meaning
+ of the option has been changed to always show "HEAD" regardless of
+ what filtering will be applied to any other ref.
+
+ This is a backward incompatible change and might cause breakages to
+ people's existing scripts.
+
+ * "git show -s" was less discoverable than it should have been. It
+ now has a natural synonym "git show --no-patch".
+
+ * "git check-mailmap" is a new command that lets you map usernames
+ and e-mail addresses through the mailmap mechanism, just like many
+ built-in commands do.
+
+ * "git name-rev" learned to name an annotated tag object back to its
+ tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0",
+ for example.
+
+ * "git cat-file --batch-check=<format>" is added, primarily to allow
+ on-disk footprint of objects in packfiles (often they are a lot
+ smaller than their true size, when expressed as deltas) to be
+ reported.
+
+ * "git rebase [-i]" used to leave just "rebase" as its reflog messages
+ for some operations. They have been reworded to be more informative.
+
+ * In addition to the choice from "rebase, merge, or checkout-detach",
+ "submodule update" can allow a custom command to be used in to
+ update the working tree of submodules via the "submodule.*.update"
+ configuration variable.
+
+ * "git submodule update" can optionally clone the submodule
+ repositories shallowly.
+
+ * "git format-patch" learned "--from[=whom]" option, which sets the
+ "From: " header to the specified person (or the person who runs the
+ command, if "=whom" part is missing) and move the original author
+ information to an in-body From: header as necessary.
+
+ * The configuration variable "merge.ff" was cleary a tri-state to
+ choose one from "favor fast-forward when possible", "always create
+ a merge even when the history could fast-forward" and "do not
+ create any merge, only update when the history fast-forwards", but
+ the command line parser did not implement the usual convention of
+ "last one wins, and command line overrides the configuration"
+ correctly.
+
* "gitweb" learned to optionally place extra links that point at the
levels higher than the Gitweb pages themselves in the breadcrumbs,
so that it can be used as part of a larger installation.
directly uses the 40-hex string as an object name, even if a ref
"refs/<some hierarchy>/<name>" exists. This disambiguation order
is unlikely to change, but we should warn about the ambiguity just
- like we warn when more than one refs/ hierachies share the same
+ like we warn when more than one refs/ hierarchies share the same
name.
* "git rebase" learned "--[no-]autostash" option to save local
response was to stash them and re-run). This introduced a corner
case breakage to "git am --abort" but it has been fixed.
- * Instead of typing four capital letters "HEAD", you can say "@" now,
- e.g. "git log @".
-
* "check-ignore" (new feature since 1.8.2) has been updated to work
more like "check-attr" over bidi-pipes.
Performance, Internal Implementation, etc.
+ * On Cygwin, we used to use our own lstat(2) emulation that is
+ allegedly faster than the platform one in codepaths where some of
+ the information it returns did not matter, but it started to bite
+ us in a few codepaths where the trick it uses to cheat does show
+ breakages. This emulation has been removed and we use the native
+ lstat(2) emulation supplied by Cygwin now.
+
+ * The function attributes extensions are used to catch mistakes in
+ use of our own variadic functions that use NULL sentinel at the end
+ (i.e. like execl(3)) and format strings (i.e. like printf(3)).
+
+ * The code to allow configuration data to be read from in-tree blob
+ objects is in. This may help working in a bare repository and
+ submodule updates.
+
+ * Fetching between repositories with many refs employed O(n^2)
+ algorithm to match up the common objects, which has been corrected.
+
* The original way to specify remote repository using .git/branches/
used to have a nifty feature. The code to support the feature was
still in a function but the caller was changed not to call it 5
been susceptible to lossage of refs under right conditions, which
has been tightened up.
- * We read loose and packed rerferences in two steps, but after
+ * We read loose and packed references in two steps, but after
deciding to read a loose ref but before actually opening it to read
it, another process racing with us can unlink it, which would cause
us to barf. The codepath has been updated to retry when such a
track are contained in this release (see release notes to them for
details).
+ * Newer Net::SMTP::SSL module does not want the user programs to use
+ the default behaviour to let server certificate go without
+ verification, so by default enable the verification with a
+ mechanism to turn it off if needed.
+ (merge 35035bb rr/send-email-ssl-verify later to maint).
+
+ * When "git" is spawned in such a way that any of the low 3 file
+ descriptors is closed, our first open() may yield file descriptor 2,
+ and writing error message to it would screw things up in a big way.
+ (merge a11c396 tr/protect-low-3-fds later to maint).
+
+ * The mailmap mechanism unnecessarily downcased the e-mail addresses
+ in the output, and also ignored the human name when it is a single
+ character name.
+ (merge bd23794 jc/mailmap-case-insensitivity later to maint).
+
+ * In two places we did not check return value (expected to be a file
+ descriptor) correctly.

- * "git stash save", when your local change turns a tracked file into

* Logic used by git-send-email to suppress cc mishandled names like
"A U. Thor" <author@example.xz>, where the human readable part
around the name, and comparison was done between quoted and
