* git-remote-mw (in contrib/) hints users to check the certificate,
when https:// connection failed.
+ * git-remote-mw (in contrib/) adds a command to allow previewing the
+ contents locally before pushing it out, when working with a
+ MediaWiki remote.
+
UI, Workflows & Features
+ * "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"
Performance, Internal Implementation, etc.
+ * 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.
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.
+ (merge a77f106 tr/fd-gotcha-fixes later to maint).
+
+ * Logic to auto-detect character encodings in the commit log message
+ did not reject overlong and invalid UTF-8 characters.
+ (merge 81050ac bc/commit-invalid-utf8 later to maint).
+
* Pass port number as a separate argument when "send-email" initializes
Net::SMTP, instead of as a part of the hostname, i.e. host:port.
This allows GSSAPI codepath to match with the hostname given.
