Easily type math in your webapp

## v0.10.1: 2016-03-21

Important fix: remove `font-size: 0` on textarea (#585), fixing typing
in Chrome Canary (#540) as well as the Enter key not triggering the
`enter` handler in Webkit and Blink (#566). `transform: scale(0)` is
used instead and expected to be much more robust.

(Note: if you're coming from v0.9.x, there've been major API changes,
see the [v0.9.x → v0.10.0 Migration Guide][].)

## v0.10.0: 2016-02-20

Many major changes including a total overhaul of the API (no more
auto-MathQuill-ifying of `.mathquill-editable` etc, and no more jQuery
plugin, instead global `MathQuill()` returns API objects, like jQuery
itself): See the [v0.9.x → v0.10.0 Migration Guide]
(https://github.com/mathquill/mathquill/wiki/v0.9.x-%E2%86%92-v0.10.0-Migration-Guide).

(If you already use the new global `MathQuill()`-based API from the
 `dev` branch, migrating to v0.10.0 should be just [one small change]
 (https://github.com/mathquill/mathquill/wiki/%60dev%60-branch-(2014%E2%80%932015)-%E2%86%92-v0.10.0-Migration-Guide)
