Let me rephrase - when was AptitudeCMS replaced with Geeklog 2.0?
Not sure what you're after.
There was, years ago, a plan to rewrite Geeklog from the ground up. That project was dubbed Geeklog 2.0. It took a long time. Tony eventually decided to rename the project to AptitudeCMS. It was released eventually, but Tony left the project shortly afterwards and it's pretty much dead now.
In the meantime, Geeklog 1.x development continued. As Tom already said, when we came to the point where the next release would have been called 1.9 but introduced a certain break in compatibility, we decided to re-use the 2.0 moniker (which hasn't really been used for anything that was actually released before).
In other words, the two projects don't share any code at all, we only re-used the name.
Does that make it clearer?
