Isotope v2 beta is out! Version 2 is a big upgrade:

• Way better support for responsive web design with element sizing options.
• Custom CSS no longer required.
• jQuery no longer required. Isotope works with vanilla JavaScript.
• getSortData shortcut strings.
• Integrated masonry features like stamp option and centering with isFitWidth
• AMD support

The beta is released so you can get aquainted with the new version before I flip the switch. As a user, you probably won't have to change much to use v2. This is a beta, so feel free to submit new issues you come across.

Happy 2014!
