Foreign interfaces, subsystems and ports.
+ * remote-hg remote helper misbehaved when interacting with a local Hg
+ repository relative to the home directory, e.g. "clone hg::~/there".
+
+ * imap-send ported to OS X uses Apple's security framework instead of
+ OpenSSL one.
+
+ * Subversion 1.8.0 that was recently released breaks older subversion
+ clients coming over http/https in various ways.
+
+ * "git fast-import" treats an empty path given to "ls" as the root of
+ the tree.
+
UI, Workflows & Features
+ * Magic pathspecs like ":(icase)makefile" that matches both
+ Makefile and makefile can be used in more places.
+
+ * The "http.*" variables can now be specified per URL that the
+ configuration applies. For example,
+
+ [http]
+ sslVerify = true
+ [http "https://weak.example.com/"]
+ sslVerify = false
+
+ would flip http.sslVerify off only when talking to that specified
+ site.
+
+ * "git mv A B" when moving a submodule A has been taught to
+ relocate its working tree and to adjust the paths in the
+ .gitmodules file.
+
+ * "git blame" can now take more than one -L option to discover the
+ origin of multiple blocks of the lines.
+
+ * The http transport clients can optionally ask to save cookies
+ with http.savecookies configuration variable.
+
+ * "git push" learned a more fine grained control over a blunt
+ "--force" when requesting a non-fast-forward update with the
+ "--force-with-lease=<refname>:<expected object name>" option.
+
+ * "git diff --diff-filter=<classes of changes>" can now take
+ lowercase letters (e.g. "--diff-filter=d") to mean "show
+ everything but these classes". "git diff-files -q" is now a
+ deprecated synonym for "git diff-files --diff-filter=d".
+
+ * "git fetch" (hence "git pull" as well) learned to check
+ "fetch.prune" and "remote.*.prune" configuration variables and
+ to behave as if the "--prune" command line option was given.
+
+ * "git check-ignore -z" applied the NUL termination to both its input
+ (with --stdin) and its output, but "git check-attr -z" ignored the
+ option on the output side. Make both honor -z on the input and
+ output side the same way.
+
* "git whatchanged" may still be used by old timers, but mention of
it in documents meant for new users will only waste readers' time
wonderig what the difference is between it and "git log". Make it
Performance, Internal Implementation, etc.
+ * Many commands use --dashed-option as a operation mode selector
+ (e.g. "git tag --delete") that the user can use at most one
+ (e.g. "git tag --delete --verify" is a nonsense) and you cannot
+ negate (e.g. "git tag --no-delete" is a nonsense). parse-options
+ API learned a new OPT_CMDMODE macro to make it easier to implement
+ such a set of options.
+
+ * OPT_BOOLEAN() in parse-options API was misdesigned to be "counting
+ up" but many subcommands expect it to behave as "on/off". Update
+ them to use OPT_BOOL() which is a proper boolean.
+
+ * "git gc" exits early without doing a double-work when it detects
+ that another instance of itself is already running.
+
+ * Under memory pressure and/or file descriptor pressure, we used to
+ close pack windows that are not used and also closed filehandle to
+ an open but unused packfiles. These are now controlled separately
+ to better cope with the load.
Also contains various documentation updates and code clean-ups.
track are contained in this release (see release notes to them for
details).
+ * The mailmap support code read past the allocated buffer when the
+ mailmap file ended with an incomplete line.
+ (merge f972a16 jk/mailmap-incomplete-line later to maint).
+
+ * We used to send a large request to read(2)/write(2) as a single
+ system call, which was bad from the latency point of view when
+ the operation needs to be killed, and also triggered an error on
+ broken 64-bit systems that refuse to take more than 2GB read or
+ write in one go.
+ (merge a487916 sp/clip-read-write-to-8mb later to maint).
+
+ * "git fetch" that auto-followed tags incorrectly reused the
+ connection with Git-aware transport helper (like the sample "ext::"
+ helper shipped with Git).
+ (merge 0f73f8b jc/transport-do-not-use-connect-twice-in-fetch later to maint).
+
+ * "git log --full-diff -- <pathspec>" showed a huge diff for paths
+ outside the given <pathspec> for each commit, instead of showing
+ the change relative to the parent of the commit. "git reflog -p"
+ had a similar problem.
+ (merge 838f9a1 tr/log-full-diff-keep-true-parents later to maint).
+
+ * Setting submodule.*.path configuration variable to true (without
+ giving "= value") caused Git to segfault.
+ (merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint).
+
+ * "git rebase -i" (there could be others, as the root cause is pretty
+ generic) fed a random, data dependeant string to 'echo' and
+ expects it to come out literally, corrupting its error message.
+ (merge 89b0230 mm/no-shell-escape-in-die-message later to maint).
+
* Some people still use rather old versions of bash, which cannot
grok some constructs like 'printf -v varname' the prompt and
completion code started to use recently.
