Hi,
Simple backgrounds are not working with the latest beta. The following has
no background color.
\setupbackground
[background=color, backgroundcolor=red]
\starttext
\startbackground
ABC
\stopbackground
\stoptext

Name clash in pack-rul.mkiv.
\startbackgorund uses \currentbackground for the instance of the environment and \framed uses also \currentbackground when it does process the list of backgrounds, changing the macro name in pack-rul.mkiv to \m_framed_background helps.

Ha, you beat me in maling ... i just changed that in the same way ...
but i was wondering why a public name was used .. can it be that
\currentbackground is used in modules or styles (e.g. implementing
alternative built in backgrounds as I remember that Aditya has some
plugs)? If so then at some point we might need a public name but let's
wait till it shows up.

I remeber using
\setupbackgrounds[page][background={bck1, \currentbackground, bck2}]
in some of my local styles. It is easy for me to adapt that.
\currentbackground is not used in any of my public modules.

maybe we can have \currentframedbackground then (if needed)
