Not sure if the hotpot module is converting ampersands correctly. $heading and $title are set up differently than in other modules: instead of outputting $course->title, a temporary $title variable is created and assigned that value. That made it difficult for me to decide whether it was already formatted elsewhere or not.
Also I didn't format_string() any of the variables included in $navigation rings, because I assume these strings get processed by print_navigation(), which includes format_string().
new function course_setup() thats does proper $CFG-> , locale and themes setup much sooner than print_header() originally (needed for MDL-8067), cleanup of forgotten global $course issues
MDL-8067 Fixed several $HTTPSREQUIRED issues - html editor now loads from https (the old hack did not wotk with IE7, new hack is uglier but works), fixed formlibs images (we can not set them in library global scope, we must wait for httpsrequired() and require_login() and od that in function), fixed links in meta.php, fixed help images
fixed setting of new $USER values in user edit forms
The API was changed slightly so that has_capability now takes the
whole $context object (we almost always have it anyway)
The $kill thing was removed. If you want to assert a capability
then use:
require_capability('capname', $context);
with optional variables to modify the error message
Misc bugs here and there also removed and code tidied
=======================================
WARNING: DEV IS CURRENTLY VERY UNSTABLE.
This is a mega-checkin of the new Roles system. A lot of changes have
been made in core and modules.
Currently there are a lot of rough edges and known problems. We are
working hard on these .. .the reason for getting this into HEAD at this
stage is enable us to move faster (our branch was diverging from HEAD
too much).
Please keep an eye on http://docs.moodle.org/en/Roles for current status
and information for developers on how to use the new Roles system.
