This viewer has fixes for some attachment-related issues, particularly when
multiple attachments are added or removed at the same time. It also has enhanced logging, so your SecondLife.log file will have some additional lines related to avatar state in general and attachments in particular.
Please file bugs for any issues seen, and attach your viewer log file with the bug report. Feedback from people who have previously had problems with attachments getting dropped or otherwise getting into the wrong state would be particularly helpful.
No birds were harmed in the making of this viewer, although one developer was bitten by a parrot.
