Topic: TinyMCE 4.0.10 Released
This release fixes two some what critical bugs with the 4.0.9 release. The scroll position wouldn't be added to the getPos call in DOMUtils and the other one was that the source editor wouldn't work on IE 11.
This release also includes fixed for selection on IE 11 and a forced_root_block_attrs option that allows you to specify attributes for the default root block.
See the changelog for details on other bug fixes.
