Have just sent in a couple of fixes for extensions to do with description.
Version 10 of Room Description Control: a minor fix to get rid of deprecated phrases. If you’re not worried about the presence of “change foo to bar”, there’s no need to update this one.
Version 4 of Single Paragraph Description: a significant bug fix. Changes to Inform internals meant that SPD was incorrectly noting which items needed to be reported in the room description. The new version gets rid of the crufty I6 inclusions of the previous version — which weren’t working right now anyway — and replaces them with native I7. It also introduces the feature of respecting BRIEF and SUPERBRIEF: in those cases, it won’t print the description text for the current room, but will still list non-scenery items.
These should show up on the extensions website soon.
