µTorrent 2.0 17920

µTorrent 2.0 17920 kent veel vernieuwingen.

Het belangrijkste is dat uTP als protocol voor bestandsoverdracht in µTorrent 2.0 sterk verbeterd is en ondersteuning voor UDP trackers is toegevoegd. Hierdoor is de betrouwbaarheid van overdrachten groter en wordt het systeem minder belast, doordat de bandbreedte die µTorrent gebruikt automatisch gereguleerd wordt. Internetverkeer van andere applicaties heeft door uTP minder te lijden onder de download van veel bestanden: de bandbreedte van µTorrent wordt automatisch 'afgeknepen'.

Verder is het installatieproces van µTorrent versimpeld en wordt nu bijgehouden hoeveel u downloadt en uploadt door middel van mooie grafiekjes.

Ten slotte zijn sinds versie 1.8.5 heel veel kleine fouten opgelost.
