Leech 1.1.3 is a mere bug fix release: Firstly, it fixes a Firefox integration bug that kept temporary download files from getting moved to their final location under certain conditions. And secondly, it removes stray temporary download files that remained visible after handing Camino downloads off to Leech.
On a side note, we have several other smallish updates coming up in the next few days, including one that solves a yFlicks/QuickTime 7.5 issue a lot of users have run into during the past few days. Thanks for your patience.
