* You can now set http.[<url>.]pinnedpubkey to specify the pinned
public key when building with recent enough versions of libcURL.
+ * The configuration system has been taught to phrase where it found a
+ bad configuration variable in a better way in its error messages.
+ "git config" learnt a new "--show-origin" option to indicate where
+ the values come from.
+
+ * The "credential-cache" daemon process used to run in whatever
+ directory it happened to start in, but this made umount(2)ing the
+ filesystem that houses the repository harder; now the process
+ chdir()s to the directory that house its own socket on startup.
+
+ * When "git submodule update" did not result in fetching the commit
+ object in the submodule that is referenced by the superproject, the
+ command learned to retry another fetch, specifically asking for
+ that commit that may not be connected to the refs it usually
+ fetches.
+
+ * "git merge-recursive" learned "--no-renames" option to disable its
+ rename detection logic.
+
+ * Across the transition at around Git version 2.0, the user used to
+ get a pretty loud warning when running "git push" without setting
+ push.default configuration variable. We no longer warn, given that
+ the transition is over long time ago.
+
+ * README has been renamed to README.md and its contents got tweaked
+ slightly to make it easier on the eyes.
+
Performance, Internal Implementation, Development Support etc.
* Help those who debug http(s) part of the system.
(merge 0054045 sp/remote-curl-ssl-strerror later to maint).
+ * The internal API to interact with "remote.*" configuration
+ variables has been streamlined.
+
+ * The ref-filter's format-parsing code has been refactored, in
+ preparation for "branch --format" and friends.
+
+ * Traditionally, the tests that try commands that work on the
+ contents in the working tree were named with "worktree" in their
+ filenames, but with the recent addition of "git worktree"
+ subcommand, whose tests are also named similarly, it has become
+ harder to tell them apart. The traditional tests have been renamed
+ to use "work-tree" instead in an attempt to differentiate them.
+ (merge 5549029 mg/work-tree-tests later to maint).
+
+ * Many codepaths forget to check return value from git_config_set();
+ the function is made to die() to make sure we do not proceed when
+ setting a configuration variable failed.
+ (merge 3d18064 ps/config-error later to maint).
+
+ * Handling of errors while writing into our internal asynchronous
+ process has been made more robust, which reduces flakiness in our
+ tests.
+ (merge 43f3afc jk/epipe-in-async later to maint).
+
+ * There is a new DEVELOPER knob that enables many compiler warning
+ options in the Makefile.

Also contains various documentation updates and code clean-ups.
broken in 2.6.0 timeframe when the command was rewritten in C.
(merge 708b8cc jc/am-i-v-fix later to maint).
+ * "git merge-tree" used to mishandle "both sides added" conflict with
+ its own "create a fake ancestor file that has the common parts of
+ what both sides have added and do a 3-way merge" logic; this has
+ been updated to use the usual "3-way merge with an empty blob as
+ the fake common ancestor file" approach used in the rest of the
+ system.
+ (merge 907681e jk/no-diff-emit-common later to maint).
+
+ * The memory ownership rule of fill_textconv() API, which was a bit
+ tricky, has been documented a bit better.
+ (merge a64e6a4 jk/more-comments-on-textconv later to maint).
+
+ * Update various codepaths to avoid manually-counted malloc().
+ (merge 08c95df jk/tighten-alloc later to maint).
+
+ * The documentation did not clearly state that the 'simple' mode is
+ now the default for "git push" when push.default configuration is
+ not set.
+ (merge f6b1fb3 mm/push-simple-doc later to maint).
+
+ * Recent versions of GNU grep are pickier when their input contains
+ arbitrary binary data, which some of our tests uses. Rewrite the
+ tests to sidestep the problem.
+ (merge 3b1442d jk/grep-binary-workaround-in-test later to maint).
+
+ * A helper function "git submodule" uses since v2.7.0 to list the
+ modules that match the pathspec argument given to its subcommands
+ (e.g. "submodule add <repo> <path>") has been fixed.
+ (merge 2b56bb7 sb/submodule-module-list-fix later to maint).
+
+ * "git config section.var value" to set a value in per-repository
+ configuration file failed when it was run outside any repository,
+ but didn't say the reason correctly.
+ (merge 638fa62 js/config-set-in-non-repository later to maint).
