Microsoft announced Internet Explorer 9 Release Candidate on Feb 10th, 2011, RC indicates except bug fixing, there would not have big changes before the final RTM. Since I've been keeping a watchful eye on IE9 from its very first preview version, I would like to write a post about its significant enhancement from a developer's point of view, I intend to summarize most significant enhancement points of IE9 listed below:
- Hardware Acceleration
- Enhanced Web Standard Support
- HTML5 (huge number of new attributes support and Web Storage support)
- CSS3 (border-radius, ::selection pseudo-element, )
- W3 standard Geolocaltion API
- Website customizable TaskBar Jumplist.
By achieving new features above, IE9 will absolutely be the fastest and best Web Standard support version in the entire IE history.
