CSS3 PIE has reached version 1.0 beta 4.This beta release is mainly about fixing bugs. Here are the main fixes:
Fixed javascript error when printing.
IE9 detection has changed: now PIE works in the compatibility mode and quirks, but it turns off in standard IE9 mode.
Fixed errors in the display of border-image, in displaying images of zero size, and some others (thanks, Keith Gable).
Prevented multiple downloads of images used on the page repeatedly.
Added support for CSS3 color keywords (thanks, Don Retzlaff).
The behavior of the border-width keywords (such as “medium”) has been fixed .
Fixed positioning elements within the RTL-text.
Added a new special CSS property-pie-poll , which allows you to specify that the PIE should periodically check whether the position and size of the element has changed. This is useful in cases where IE does not create the “onmove” and “onresize” events, although it should.
After this fourth beta, development will mainly focus on the implementation of correct support for CSS3 properties in IE9, which are absent there, primarily “linear-gradient”and “border-image”.
