+Git v2.7.3 Release Notes
+========================
+
+Fixes since v2.7.2
+------------------
+
+ * 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.
+
+ * 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.
+
+ * Handling of errors while writing into our internal asynchronous
+ process has been made more robust, which reduces flakiness in our
+ tests.
+
+ * "git show 'HEAD:Foo[BAR]Baz'" did not interpret the argument as a
+ rev, i.e. the object named by the the pathname with wildcard
+ characters in a tree object.
+
+ * "git rev-parse --git-common-dir" used in the worktree feature
+ misbehaved when run from a subdirectory.
+
+ * The "v(iew)" subcommand of the interactive "git am -i" command was
+ broken in 2.6.0 timeframe when the command was rewritten in C.
+
+ * "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.
+
+ * The memory ownership rule of fill_textconv() API, which was a bit
+ tricky, has been documented a bit better.
+
+ * The documentation did not clearly state that the 'simple' mode is
+ now the default for "git push" when push.default configuration is
+ not set.
+
+ * 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.
+
+ * 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.
+
+ * "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.
+
+ * The code to read the pack data using the offsets stored in the pack
+ idx file has been made more carefully check the validity of the
+ data in the idx.
+
+Also includes documentation and test updates.
and if it is not found, honors `push.default` configuration to decide
what to push (See linkgit:git-config[1] for the meaning of `push.default`).
+When neither the command-line nor the configuration specify what to
+push, the default behavior is used, which corresponds to the `simple`
+value for `push.default`: the current branch is pushed to the
+corresponding upstream branch, but as a safety measure, the push is
+aborted if the upstream branch does not have the same name as the
+local one.

`argv_array_clear`::
Free all memory associated with the array and return it to the
initial, empty state.
+
+`argv_array_detach`::
+ Disconnect the `argv` member from the `argv_array` struct and
+ return it. The caller is responsible for freeing the memory used
+ by the array, and by the strings it references. After detaching,
+ the `argv_array` is in a reinitialized state and can be pushed
+ into again.
