In the end the new version of share took a couple of days more than I anticipated, but it was worth it. Here's the announcement in the forums. Probably the most visible change is the improved queue manager, which maintains local and remote queues synchronized transparently (but allows asynchronous queue management, that is, it is irrelevant whether the contact that is sharing the files is online or not).

This has kept me quite busy the last few days--now for a short break (and maybe some more blogging :)).
