+Git v2.1.3 Release Notes
+========================
+
+ * 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.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+ use the hostname even when gethostbyname() reported that the given
+ hostname is not found.
+
+ * Newer versions of 'meld' breaks the auto-detection we use to see if
+ they are new enough to support the `--output` option.
+
+ * "git pack-objects" forgot to disable the codepath to generate
+ object recheability bitmap when it needs to split the resulting
+ pack.
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+ CGI.pm as of 4.04; use CGI::start_from instead.
+
+ * "git log" documentation had an example section marked up not
+ quite correctly, which passed AsciiDoc but failed with
+ AsciiDoctor.
+
+Also contains some documentation updates.
* The support to build with NO_PTHREADS has been resurrected.
+ * Compilation options has been updated a bit to support z/OS port
+ better.
+
UI, Workflows & Features
to replace blob contents, names of people and paths and log
messages with bland and simple strings to help them.
+ * "git difftool" learned an option to stop feeding paths to the
+ diff backend when it exits with a non-zero status.
+
* "log --date=iso" uses a slight variant of ISO 8601 format that is
made more human readable. A new "--date=iso-strict" option gives
datetime output that is more strictly conformant.
+ * The logic "git prune" uses is more resilient against various corner
+ cases.
+
* A broken reimplementation of Git could write an invalid index that
records both stage #0 and higher stage entries for the same path.
We now notice and reject such an index, as there is no sensible
creted temporary directory, instead of the current directory, by
setting the mergetool.writeToTemp configuration variable.
+ * "git mergetool" understands "--tool bc" now, as version 4 of
+ BeyondCompare can be driven the same way as its version 3 and it
+ feels awkward to say "--tool bc3".
+
* The "pre-receive" and "post-receive" hooks are no longer required
to consume their input fully (not following this requirement used
to result in intermittent errors in "git push").
array for child process, alleviating the need for the callers to
allocate and deallocate them.
+ * Some people use AsciiDoctor, instead of AsciiDoc, to format our
+ documentation set; the documentation has been adjusted, as
+ AsciiDoctor is pickier than AsciiDoc in its input mark-up.
+
Also contains various documentation updates and code clean-ups.

maximum depth is given on the command line. Defaults to 50.
pack.windowMemory::
- The window memory size limit used by linkgit:git-pack-objects[1]
- when no limit is given on the command line. The value can be
- suffixed with "k", "m", or "g". Defaults to 0, meaning no
- limit.
+ The maximum size of memory that is consumed by each thread
+ in linkgit:git-pack-objects[1] for pack window memory when
+ no limit is given on the command line. The value can be
+ suffixed with "k", "m", or "g". When left unconfigured (or
+ set explicitly to 0), there will be no limit.
pack.compression::
An integer -1..9, indicating the compression level for objects
the default diff tool will be read from the configured
`diff.guitool` variable instead of `diff.tool`.
+--[no-]trust-exit-code::
+ 'git-difftool' invokes a diff tool individually on each file.
+ Errors reported by the diff tool are ignored by default.
+ Use `--trust-exit-code` to make 'git-difftool' exit when an
+ invoked diff tool returns a non-zero exit code.
++
+'git-difftool' will forward the exit code of the invoked tool when
+'--trust-exit-code' is used.
+
See linkgit:git-diff[1] for the full list of supported options.
CONFIG VARIABLES
difftool.prompt::
Prompt before each invocation of the diff tool.
+difftool.trustExitCode::
+ Exit difftool if the invoked diff tool returns a non-zero exit status.
++
+See the `--trust-exit-code` option above for more details.
+

explicitly.
+--reflog::
+ Pretend as if all objects mentioned by reflogs are listed on the

+# This test covers the handling of objects which might have old
+# mtimes in the filesystem (because they were used previously)
+# and are just now becoming referenced again.
+#
+# We're going to do two things that are a little bit "fake" to
+# help make our simulation easier:
+#
+# 1. We'll turn off reflogs. You can still run into
+# problems with reflogs on, but your objects
+# don't get pruned until both the reflog expiration
+# has passed on their references, _and_ they are out
+# of prune's expiration period. Dropping reflogs
+# means we only have to deal with one variable in our tests,
+# but the results generalize.
+#
+# 2. We'll use a temporary index file to create our
+# works-in-progress. Most workflows would mention
+# referenced objects in the index, which prune takes
+# into account. However, many operations don't. For
+# example, a partial commit with "git commit foo"
+# will use a temporary index. Or they may not need
+# an index at all (e.g., creating a new commit
+# to refer to an existing tree).

+# We care about reachability, so we do not want to use
+# the normal test_commit, which creates extra tags.
