Chromium 11.0 was released on 28 January 2011, with 11.0.652.0 as the initial version. Development work in this version centered on cleaning up the settings menu, including the Sync menu and eliminating all checkboxes. Reviewer Wolfgang Gruener said "The Settings menu isn’t quite as messy anymore and looks much more like what you would expect from a professionally designed software." Language and spell checking support was expanded to 100 languages. Chromium 11 used WebKit 534.18 and V8 3.1.1 which resulted in improved speed in JavaScript and other benchmark tests. In early testing Chromium 11 was faster than Firefox 4 in V8 and Kraken benchmarks, but was 12% slower than Internet Explorer 9 in Sunspider tests
