10.2.0

The 10.2 release adds an experimental Flow layer to render particle flows (e.g. wind) in WebGL, support for WMS Capabilities v1.1.1, and an ol.VERSION property in the legacy build. Under the hood, it brings several performance improvements, better memory management, bug fixes, type improvements, and the removal of unnecessary tile caching code.
