The latest update patch is here:

• Large addressing: PD Pro was built with large addressing flags to enable working with very large images. Note: 32-bit Windows programs can address a max of 2 GB. That doesn't mean they'll be able to allocate that much memory from the system. Certain versions of Windows (XP Pro) can be patched to address 3 GB if the software is compiled to support it. Under 64 bit windows, we should be able to address the full 4 GB space that 32 bit addressing allows.

• Marching Ants visibility along selection boundaries can be toggled on/off. This can be useful for clarity in identifyling what's been selected (e.g. after a magic wand use on very noisy imagery). It can also significantly speed up the work process. This is a feature for pro users who work faster than they think: If PD Pro is in your blood, and you know what you're doing even when you don't see it onscreen, then this is for you.

• fixed a bug in the Feather plugin

happy waffling!
