Adobe did a great job with continued upgrade support, even when you keep an old version on your machine. After installing version 2.0 beta, I found an interesting and very good side effect.
All my settings, templates and presets from version 1.3 were available in 2.0! This makes testing the beta that much easier!
I'm working on getting some images in a library and I'll keep you updated with some Library and Develop module information! The interface looks great and I can already tell there are some fantastic additions.
Don't forget to visit my photography web site where we sell museum quality black and white prints framed to last up to 175 years - Outdoor Images Fine Art.
