They have all been tested on multiple systems. Also many of the changes are
related to things that didn't work at all previously so there was little scope

Below is the definition of gnome_role, when it is called the first parameter
$1 equals the second parameter $2 from the above optional_policy and $2 is the
$1_dbusd_t. So it substitutes to domain_auto_trans($1_dbusd_t, gconfd_exec_t,
gconfd_t). That matches the description in the changelog.
type gconfd_t, gconfd_exec_t;
role $1 types gconfd_t;
allow gconfd_t $2:fd use;
allow gconfd_t $2:fifo_file write;
allow gconfd_t $2:unix_stream_socket connectto;
read_files_pattern($2, gconf_tmp_t, gconf_tmp_t)
allow $2 gconfd_t:unix_stream_socket connectto;

You are correct, I've removed that now.

Again you are correct, I've removed that too.
Now what's the procedure for uploading it? Do I just replace "unstable" with
"stable" in the changelog, use the version number you requested, and then
