Hi,
Is this a bug or not ?
The key to coloring the background of the text seems to no longer work.
There is a problem with the corner option, you can either hope it gets
fixed in the next release
(corner=round still works) or create your own background as metapost
graphic with rounded corners.
Oh, yes, here’s Hans’ fix.
