The last available version can be downloaded here. Don't expect too much, use v1.10 for any serious work. Don't send me requests for features already available in v1.10. Please report only serious bugs and crashes. And, of course, new ideas are always welcome!
Pre-alpha 5: hit trace! Maybe you have tried to use hit trace in the version 1.10, only to discover that it doesn't work with non-trivial programs. Hit trace in version 2 is different: instead of replacing all recognized commands with INT3, I set breakpoints dynamically on all non-processed branches. It seems that 20-30 thousand breakpoints is not a problem for the new debugger. Also in this release: just-in-time debugging, command line, several bugfixes. Help on command is ready for all non-SSE/non-FPU commands till LEA.
