State of jQuery - Part 2 - Sizzle
summary
jQuery 1.8 ships with a rewritten Sizzle that raises matching and filtering speed about 5–10% overall and speeds element-rooted ID selections by roughly ~300%, adds simple-selector shortcuts to IE6–8, and improves QSA/matchSelector failure detection to bypass buggy native paths. Several combinator and attribute edge cases are fixed, selector validation is stricter, upcoming work targets CSS3 selectors like nth-of-type and :target, and the project uses grunt with linting and GitHub issue tracking.
