jQuery 1.10.0 and 2.0.1 Released | Official jQuery Blog
jQuery 1.10.0 and 2.0.1 shipped together, on the fifth anniversary of 1.2.6, with the aim of bringing the 1.x line (which still supports IE 6–8) and the 2.x line (which doesn't) back into feature parity, a sync the team promises to maintain, so 1.11 and 2.1 will match. The changes are mostly non-disruptive: leading whitespace is allowed again in `$(htmlString)`, custom builds can drop the `.wrap*`/`.unwrap` methods and optionally `.bind`/`.delegate`, and there are workarounds for the IE9 iframe focus error and for Cordova's `deviceready` event target. The post also credits contributors and gives full bug-by-bug changelogs for each version, plus reminders about the 1.9 upgrade guide and the Migrate plugin for older code.
