This files describes API changes in the editor_atto code.
=== 3.0 ===
* Rangy updated to 1.3.0.
  Rangy has deprecated the createCssClassApplier function in this version (it is now createClassApplier).

=== 2.9 ===

* When adding a shortcut to the button of a plugin, atto will add a layer of validation
to ensure that only the required keys are pressed. However, if you are using a custom
keyConfig object you must validate the shortcut yourself. This is particularly important
for non-English keyboard users. For more information read the documentation of
EditorPluginButtons::_addKeyboardListener() and MDL-47133.
