Just in time of my release of the Magento boilerplate with CSS3PIE the guys from 327 Creative LLC released beta 3 of their life saving Progressive IE .htc script.

Here’s the rundown of improvements:

1. Performance – PIE is now up to four times as fast as beta2.
2. Lazy Initialization –  PIE loads on demand
3. PIE.js: standalone JavaScript version – for situations when you can’t use .htc
4. Works on table elements – Sit around the rounded table…
5. Works on images - Rounded images work too (worked for me in beta2)

And the rest of it is on their blog to read.
