3.4.5 includes Internet Explorer Out Of Process (IEOOP) functionality. It changes how the app handles HTML content (now out-of-process) for a significant improvement in stability, 50% to be exact. This sets a new standard for µTorrent’s already-low crash rate. A big thank you to all of the µTorrent engineers who have worked so hard on this.

What does this mean for users?



  • Crashes and odd behavior triggered by HTML/Flash content will be isolated and not crash µTorrent/BitTorrent



  • The client team will now have a clearer picture of what the common crashes look like for µTorrent/BitTorrent, so that we can focus on crashes affecting client functionality.



  • We’ve had reports of better/more reliable font rendering and more consistent javascript behavior.



Here’s one of the graphs we use to measure build performance: (Note: these graphs show relative, not absolute, crash-rates)
