I found this over at androidforum.com. It is the third version of the 2.1 leak..there is also a change log listing the updates. I have flashed it to my phone and have been running it for about an hour and so far havent noticed a significant difference with the exception of being able to download more htc widgets such as daily challenge, battery, etc. I am not sure if that was fixed in the 2nd version of the leak.
