Git v2.9.1 Release Notes
========================

Fixes since v2.9
----------------

 * When "git daemon" is run without --[init-]timeout specified, a
   connection from a client that silently goes offline can hang around
   for a long time, wasting resources.  The socket-level KEEPALIVE has
   been enabled to allow the OS to notice such failed connections.

 * The commands in `git log` family take %C(auto) in a custom format
   string.  This unconditionally turned the color on, ignoring
   --no-color or with --color=auto when the output is not connected to
   a tty; this was corrected to make the format truly behave as
   "auto".

 * "git rev-list --count" whose walk-length is limited with "-n"
   option did not work well with the counting optimized to look at the
   bitmap index.

 * "git show -W" (extend hunks to cover the entire function, delimited
   by lines that match the "funcname" pattern) used to show the entire
   file when a change added an entire function at the end of the file,
   which has been fixed.

 * The documentation set has been updated so that literal commands,
   configuration variables and environment variables are consistently
   typeset in fixed-width font and bold in manpages.

 * "git svn propset" subcommand that was added in 2.3 days is
   documented now.

 * The documentation tries to consistently spell "GPG"; when
   referring to the specific program name, "gpg" is used.

 * "git reflog" stopped upon seeing an entry that denotes a branch
   creation event (aka "unborn"), which made it appear as if the
   reflog was truncated.

 * The git-prompt scriptlet (in contrib/) was not friendly with those
   who uses "set -u", which has been fixed.

 * A codepath that used alloca(3) to place an unbounded amount of data
   on the stack has been updated to avoid doing so.

 * "git update-index --add --chmod=+x file" may be usable as an escape
   hatch, but not a friendly thing to force for people who do need to
   use it regularly.  "git add --chmod=+x file" can be used instead.

 * Build improvements for gnome-keyring (in contrib/)

 * "git status" used to say "working directory" when it meant "working
   tree".

 * Comments about misbehaving FreeBSD shells have been clarified with
   the version number (9.x and before are broken, newer ones are OK).

 * "git cherry-pick A" worked on an unborn branch, but "git
   cherry-pick A..B" didn't.

Also contains minor documentation updates and code clean-ups.
