Here is the list of CSS features and changes for IE7:
Bugs we fixed

All bugs on /* Position Is Everything */ — Modern browser bugs explained in detail! except the “escaping floats” bug (which is planned for the future)

Details on some of the other bugs (from sources other than the positioniseverything.net list) that we fixed:

Overflow now works correctly! (That means boxes do not automatically grow any more.)
Parser bugs: * html, _property and /**/ comment bug
Select control: CSS style-able and not always on top
Auto-sizing of absolute positioned element with width and right & left (great for 3 column layouts)
Addressed many relative positioning issues
Addressed many absolute positioned issues
% calculations for height/width for abs positioned elements CSS video sample files
<?xml> prolog no longer causes quirks mode
HTML element truly independent of the Body (now gets its own width, height etc.)
1 px dotted borders no longer render as dashed
Bottom margin bug on hover does not collapse margins
Several negative margin issues fixed
Recalc issues including relative positioning and/or negative margins are fixed now
CLSID attribute of <object> tag no longer limited to 128 characters
:first-letter whitespace bug described in http://blogs.msdn.com/ie/archive/2005/09/02/460115.aspx fixed
Descendant selector now works properly for grand children when combined with other selectors
First-line and first-letter now applies when there is no space between word :first-line and opening brace {
Pseudo-classes now are working as expected if selector is excluded
The :link selector works now for anchor tag with href set to bookmark
Addressed !important issues
PositionIsEverything piefecta-rigid.htm now works
List-item whitespace bug fixed
Fixed Absolutely Buggy II
Absolute positioned elements now use always correct containing block for positioning and size information
Nested block elements now respect all overflow declarations (hidden, scroll, etc)
Fixed the opposing offset problem (absolute positioned element whit all four top, bottom left and right are present)
<a> tags nested within LI elements will no longer add extra bottom margin when hover occurs
We no longer lose the image aspect ratio on refresh
Cleaned up our ident parsing according to CSS2.1 rules
Fixed parsing bugs for multi- class selectors and class selectors that are combined with id selectors
And many more

We also extended our existing implementations to comply with W3C specifications:

Enable :hover on all elements not just on <a>
Background-attachment: fixed works on all elements – so Eric Meyer’s complexspiral demo works
Improved <object> fallback

Finally, we added new features from CSS2.1:

Min/max width/height support (also for images, which did not work in IE7b2)
Transparent borders
Fixed positioning support
Selectors: first-child, adjacent, attribute, child
- A couple of CSS 3 attribute selectors: prefix, suffix and substring since we were working already in the code base (also the general sibling selector)
Alpha channel PNG support (Not a CSS feature but too important for designers to not call it out J)
