I have just updated my MikTeX 2.9 (I'm using Windows 7)... and surprise! My citations don't work any more and I get cryptic error messages. Panic! After a few minutes of frantic and more or less random trial and (inevitably) error attempts, I decided to read the manual. (Yep, should have started with that one!)
So I learn that biblatex 2.0 uses biber as back-end and I need to specify explicitly that I want to force it to use the old bibtex back-end. Works fine, thanks! Still, the documentation also says that if the back-end is bibtex, biblatex will revert to version 1.7. So my question is: where do I find the documentation for biblatex 1.7? (Googling didn't help...) Or for that matter documetation for older versions of LaTeX packages?
P.S. Don't tell me to switch to biber! I intend to do that... in due time. For now I have a large document that still needs some serious editing and absolutely no urge to experiment... Thanks for your understanding! :)
