Between the release of version 1.10 and 2.0, there was a similar period of activity decline on the ollydbg website. Since ollydbg seems to be a hobby for the author, I assume he only has the opportunity continue development during his free time. I suppose that is why new version releases occur very seldomly. I believe that the author would at least make an anouncement on the website if development were discontinued. If he were to cease development of ollydbg, I hope he would choose to release the source code so others can continue development of the "perfect" ring 3 debugger.
