Fresh from the Adobe Labs comes betas for Adobe Dreamweaver CS4 and Adobe Fireworks CS4. It should be noted that if you’ve been using CS3, there is a new unified interface that’ll be appearing in CS4 that may take some getting used to.
Also, if you tested the Photoshop CS3 beta when it was released, I can’t stress enough that you should not install this software on a machine that is mission critical for your business. This is beta software. It may have problems. It may cause difficulties if you decide to upgrade to CS4 when it’s released.
Caveat emptor.
