=== JS ===
* landed https://bugzilla.mozilla.org/show_bug.cgi?id=200505. big perf win on some benchmarks.
* looked some at Google's [http://code.google.com/p/sputniktests/ Sputnik] ES3 testsuite
** none of our existing failures are too serious
** some errors are codified in ES5
** a large number of existing failures can be tracked to giving native functions (those built into ES5 itself) .prototype
** many also due to reading all input as ASCII when Sputnik expects UTF-8, see {{bug|495970}} and {{bug|501265}}, probably will switch to read input as UTF-8 for simplicity
** work on bugfixes probably not particularly high-priority, will keep an eye on things as UTF-8 and similar bugs are fixed to clear out the low-hanging fruit
