+Git v1.7.4 Release Notes (draft)
+================================
+
+Updates since v1.7.3
+--------------------
+
+ * The option parsers of various commands that create new branch (or
+   rename existing ones to a new name) were too loose and users were
+   allowed to call a branch with a name that begins with a dash by
+   creative abuse of their command line options, which only lead to
+   burn themselves.  The name of a branch cannot begin with a dash
+   now.
+
+ * System-wide fallback default attributes can be stored in
+   /etc/gitattributes; core.attributesfile configuration variable can
+   be used to customize the path to this file.
+
+ * "git diff" and "git grep" learned how functions and subroutines
+   in Fortran look like.
+
+ * "git log -G<pattern>" limits the output to commits whose change has
+   added or deleted lines that match the given pattern.
+
+ * "git read-tree" with no argument as a way to empty the index is
+   deprecated; we might want to remove it in the future.  Users can
+   use the new --empty option to be more explicit instead.
+
+ * "git merge --log" used to limit the resulting merge log to 20
+   entries; this is now customizable by giving e.g. "--log=47".
+
+ * you can extend "git shell", which is often used on boxes that allow
+   git-only login over ssh as login shell, with custom set of
+   commands.
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.3
+------------------
+
+All of the fixes in v1.7.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git log --author=me --author=her" did not find commits written by
+   me or by her; instead it looked for commits written by me and by
+   her, which is impossible.

 NAME

-git-shell - Restricted login shell for GIT-only SSH access
+git-shell - Restricted login shell for Git-only SSH access
 
 
 SYNOPSIS
 --------
-'$(git --exec-path)/git-shell' -c <command> <argument>
+'git shell' [-c <command> <argument>]
 
 DESCRIPTION
 -----------
-This is meant to be used as a login shell for SSH accounts you want
-to restrict to GIT pull/push access only. It permits execution only
-of server-side GIT commands implementing the pull/push functionality.
-The commands can be executed only by the '-c' option; the shell is not
-interactive.
-
-Currently, only four commands are permitted to be called, 'git-receive-pack'
-'git-upload-pack' and 'git-upload-archive' with a single required argument, or
-'cvs server' (to invoke 'git-cvsserver').
+
+A login shell for SSH accounts to provide restricted Git access. When
+'-c' is given, the program executes <command> non-interactively;
+<command> can be one of 'git receive-pack', 'git upload-pack', 'git
+upload-archive', 'cvs server', or a command in COMMAND_DIR. The shell
+is started in interactive mode when no arguments are given; in this
+case, COMMAND_DIR must exist, and any of the executables in it can be
+invoked.
+
+'cvs server' is a special command which executes git-cvsserver.
+
+COMMAND_DIR is the path "$HOME/git-shell-commands". The user must have
+read and execute permissions to the directory in order to execute the
+programs in it. The programs are executed with a cwd of $HOME, and
+<argument> is parsed as a command-line string.

+Sample programs callable through git-shell.  Place a directory named
+'git-shell-commands' in the home directory of a user whose shell is
+git-shell.  Then anyone logging in as that user will be able to run
+executables in the 'git-shell-commands' directory.
+
+Provided commands:
+
+help: Prints out the names of available commands.  When run
+interactively, git-shell will automatically run 'help' on startup,
+provided it exists.
+
+list: Displays any bare repository whose name ends with ".git" under
+user's home directory.  No other git repositories are visible,
+although they might be clonable through git-shell.  'list' is designed
+to minimize the number of calls to git that must be made in finding
+available repositories; if your setup has additional repositories that
+should be user-discoverable, you may wish to modify 'list'
+accordingly.
