Mozilla just opened the new source repository (mozilla-central) meaning the next release features will start landing. David Baron posted about landing new CSS selectors. Robert O’Callahan posted about some kick-ass SVG-based CSS effects used to style HTML. This totally rocks and will help push SVG into more of a leading role on the Web.
Look for more cool features, big and small, to start landing with increasing frequency. Some will help chrome developers while others are focused on web developers.
