UI, Workflows & Features
+ * "git archive" learned to filter what gets archived with pathspec.
+
* "git config --edit --global" starts from a skeletal per-user
configuration file contents, instead of a total blank, when the
user does not already have any. This immediately reduces the
to consume their input fully (not following this requirement used
to result in intermittent errors in "git push").
+ * The pretty-format specifier "%d", which expanded to " (tagname)"
+ for a tagged commit, gained a cousin "%D" that just gives the
+ "tagname" without frills.
+
+ * "git push" learned "--signed" push, that allows a push (i.e.
+ request to update the refs on the other side to point at a new
+ history, together with the transmission of necessary objects) to be
+ signed, so that it can be verified and audited, using the GPG
+ signature of the person who pushed, that the tips of branches at a
+ public repository really point the commits the pusher wanted to,
+ without having to "trust" the server.
Performance, Internal Implementation, etc.
all-or-none atomic updates and migrating the storage to something
other than the traditional filesystem based one (e.g. databases).
+ * The lockfile API and its users have been cleaned up.
+
* We no longer attempt to keep track of individual dependencies to
the header files in the build procedure, relying on automated
dependency generation support from modern compilers.
* "git hash-object" was taught a "--literally" option to help
debugging.
+ * When running a required clean filter, we do not have to mmap the
+ original before feeding the filter. Instead, stream the file
+ contents directly to the filter and process its output.
Also contains various documentation updates and code clean-ups.
* "git checkout -m" did not switch to another branch while carrying
the local changes forward when a path was deleted from the index.
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+ use the hostname even when gethostbyname() reported that the given
+ hostname is not found.
+ (merge 107efbe rs/daemon-fixes later to maint).
+
* With sufficiently long refnames, "git fast-import" could have
overflown an on-stack buffer.
* Use of "--verbose" option used to break "git branch --merged".
(merge 12994dd jk/maint-branch-verbose-merged later to maint).
+
+ * Some MUAs mangled a line in a message that begins with "From " to
+ ">From " when writing to a mailbox file and feeding such an input
+ to "git am" used to lose such a line.
+ (merge 85de86a jk/mbox-from-line later to maint).
+
+ * "rev-parse --verify --quiet $name" is meant to quietly exit with a
+ non-zero status when $name is not a valid object name, but still
+ gave error messages in some cases.
+
+ * A handful of C source files have been updated to include
+ "git-compat-util.h" as the first thing, to conform better to our
+ coding guidelines.
+ (merge 1c4b660 da/include-compat-util-first-in-c later to maint).
+
+ * t7004 test, which tried to run Git with small stack space, has been
+ updated to give a bit larger stack to avoid false breakage on some
+ platforms.
+ (merge b9a1907 sk/tag-contains-wo-recursion later to maint).
+
+ * A few documentation pages had example sections marked up not quite
+ correctly, which passed AsciiDoc but failed with AsciiDoctor.
+ (merge c30c43c bc/asciidoc-pretty-formats-fix later to maint).
