Nice, 2.1 alphas haven't been working on my computer (Win7 x64). This seems to work fine.
Offline
Problem with upload even when uTP is off (bt.transp_disposition 5) 
Offline
are there any plans to add a preference option to disable the ui hang reporting?
Offline
Thanks , I'm testing it now

PS : I hope someday Utorrent won't require port forwarding

uTP can do NAT traversal. It will often succeed in holepunching through NAT, even if your port is closed.
rapizemun, there is no issue. Overhead calculation is turned on now and TCP does generate overhead. It's not using more bandwidth, it's just showing you the true bandwidth use. Turning uTP off doesn't make the inherent TCP overhead go away. You should try uTP again though, it should have less overhead than 2.0 stable.

http://www.mediafire.com/?4ynunnqmeog | 100% CPU hang, was toggling gui.graph_tcp_rate_control, and sometimes gui.graph_legend.
Also noticed the legend is useless with graph tcp rate control. Has the behavior of net.calc_overhead been changed? What are these purple lines supposed to represent?
Offline
Some observations/bugs:
1. I've noticed a possible issue with # of peers of TCP trackers, that seem to not correlate to the total peers/list (total being much larger)
2. download is stopped when downloading in uTP (10) and changing DL limit to infinity
3. Better default for uTP packet size for me was 8 (1438 bytes)
4. Some cases of "hard to connect" to another 2.01 client
5. Minor GUI issues:
- redundant "send rate to player" in 2 graphs
- UL=DL limit graphs shows only the upload limit
- resizing speed graph is slow if the legend is on
6. incidents of uT "not responding" after trying to stop a torrent that is downloading with both DL speed limitter and upload speed limitter set (limitted by the DL limit, AND the speed-graph tab- in view)
More details - were emailed to the devs...

Try uTP again bt.transp_disposition 15 even old behawer on 1.8.xx 13 only upload but same

Another dump, this time the window disappeared and the process was consuming CPU: http://www.mediafire.com/?3zz33ix2znz

GTHK: next release will fix your high CPU bug.

2.0.1 is 2.0 based. 2.1 is a different branch. Very different.

why i cant update my utorrent via utorrent? i mean i have "download betas" enabled but there is no updates it can find
Offline
While a beta is very new it is just tested by users who download them on the forum here to catch any major problems, that way they avoid sending out buggier builds to larger populations.
Offline
YES thats why there is a "download betas" option in uTorrent man. coz i wanna download betas via utorrent!
Offline
They do roll out via autoupdater to those with that option checked, only a day or so later to avoid sending out builds with any showstopping crashes, etc. The two-tiered system makes sense IMO.

Forum first, then auto-update. We always do this.

a frustrating download-test
Seed: uT 2.01 , uTP only (10) , a few tasks running, a test-torrent seeding.
3 upload slots per torrent, 10+ concurrent / downloading tasks
below the set upload limit
Peer: uT 2.01 , uTP only (10, then 15), only one downloading task for the above torrent, DHT/PEX - disabled
Peer list: 1. own IP (89...)
2. seed IP (68...)
3. ISP cache IP (not supporting uTP) (212...)
Both used encryption. Task added using a magnet link , and the peer IP was added manually.
Tracker was updated with the seed (just in case) and listed a single peer:
http://tracker.openbittorrent.com/announce working 27m 49s 0 1 30m 8s 15m 4s 5
Download was intermittent when active, very low speed, and long time gaps (minutes) w/o any traffic.
Is there any reason for a traffic to a single peer from a "dedicated" task on the seed to NOT be , at least, continuous ? (btw, using TCP - all was well!)
On one accasion I have managed to "catch" s screenshot of TWO concurrent sessions with the seeder:

Seldomly, the log shows using another port on the seed - 1890 here - for "agregated data":

Also: after turning from downloading to a seeding state - it was impossible for a donwloader (68.x.x.x) to connect to that seed for downloading. Just re-starting of uTorrent - enabled it for seeding again.
A log in this case shows "Disconnect: Not downloading":

Add Torrents silently does not work in Windows 7.. it always opens the window.
