Software Update: µTorrent 2.0 Build 16081 Beta

Spread the love

A new beta of µTorrent was released on Tuesday. The first thing to notice is that the program no longer carries version number 1.9, but has been upgraded to 2.0. µTorrent is a very complete BitTorrent client that uses very little memory and processor, and the size of the program itself is minimal. The most important improvement in version 2.0 is the support for uTP: a way of data transport where high reliability and minimal latencies are the spearheads. The last development version dates back to the beginning of April and the changelog of this release is long:

New features:

  • New Setup guide & Speedtest.
  • Add Moldova to peer flags
  • UDP tracker support
  • New installer with EULA, file association
  • Grayscale disabled toolbar buttons
  • uTP supports window sizes smaller than the packet size
  • enable and disable toolbar buttons according to selected torrents
  • New “Transfer Cap” pane in Preferences
  • uTP can be enabled or disabled using “Enable bandwidth management” checkbox in Preferences


  • Added upnp host cache to speed up upnp nat resolution on misbehaving routers
  • If selected, install start menu and desktop shortcuts to all users instead of only current user
  • Disable toolbar offers for Wine installs
  • Uninstaller is added to all user profiles
  • Incomplete downloads sort after completed downloads if sorting by “Completed On”
  • Prompt to take associations in installer only if any others exist
  • Reduced uTP overhead slightly by ramping up packet sizes at lower rates
  • UAC must be completed to install in Vista or higher
  • Tweaks to Ask toolbar offer
  • Added support for 3:rd party applications to more easily be configured to access the uTorrent web UI, ie to pair the applications
  • Torrent whose “Force Recheck” is greyed out will not recheck when asked through multi-torrent selections

Bug fixed:

  • Crash when assigning new label to torrents from RSS
  • Maintain category list selection on update for some edge cases
  • Fixed uTP selective ack bug (would cause connections to stall and time out)
  • Fixed uTP fast re-send bug (would sometimes re-send packets that shouldn’t be re-sent)
  • Buffer overrun vulnerability in create torrent dialog
  • uTP recovers faster after timeout
  • Memory leaks in main window, protocol associations, settings dialog, general tab
  • Only change run on startup if installer is shown
  • Make “alternate upload rate when seeding” apply when the seeding is set by the scheduler
  • Align “Web Seeds” in torrent creation dialog
  • Translated strings in uninstaller
  • Http seeds would not reconnect after stopping and starting torrent
  • Http seed for multifile torrents
  • Regression in 15562 that caused frequent crashes
  • uTP issue on low-latency high-throughput networks
  • Copying long filenames to clipboard no longer results in garbage or crash
  • Fixed web seed support for multi-file torrents
  • When adding torrents through URLs via commandline, we would always open the add torrent dialog
  • Handle multi file torrents with web seed urls that incorrectly don’t end with a slash
  • Make sure web seed urls end with a slash for multifile torrents
  • Setup Vista firewall
  • Remove settings on Vista during un-installation
  • Check at startup for incompatible versions of NVIDIA nForce firewall
