Git v2.13.2 Release Notes
=========================

Fixes since v2.13.1
-------------------

 * The "collision detecting" SHA-1 implementation shipped with 2.13.1
   was still broken on some platforms.  Update to the upstream code
   again to take their fix.

 * "git checkout --recurse-submodules" did not quite work with a
   submodule that itself has submodules.

 * Introduce the BUG() macro to improve die("BUG: ...").

 * The "run-command" API implementation has been made more robust
   against dead-locking in a threaded environment.

 * A recent update to t5545-push-options.sh started skipping all the
   tests in the script when a web server testing is disabled or
   unavailable, not just the ones that require a web server.  Non HTTP
   tests have been salvaged to always run in this script.

 * "git clean -d" used to clean directories that has ignored files,
   even though the command should not lose ignored ones without "-x".
   "git status --ignored"  did not list ignored and untracked files
   without "-uall".  These have been corrected.

 * The timestamp of the index file is now taken after the file is
   closed, to help Windows, on which a stale timestamp is reported by
   fstat() on a file that is opened for writing and data was written
   but not yet closed.

 * "git pull --rebase --autostash" didn't auto-stash when the local history
   fast-forwards to the upstream.

 * "git describe --contains" penalized light-weight tags so much that
   they were almost never considered.  Instead, give them about the
   same chance to be considered as an annotated tag that is the same
   age as the underlying commit would.

 * The result from "git diff" that compares two blobs, e.g. "git diff
   $commit1:$path $commit2:$path", used to be shown with the full
   object name as given on the command line, but it is more natural to
   use the $path in the output and use it to look up .gitattributes.

 * A flaky test has been corrected.

 * Help contributors that visit us at GitHub.

 * "git stash push <pathspec>" did not work from a subdirectory at all.
   Bugfix for a topic in v2.13

Also contains various documentation updates and code clean-ups.
