+## Breaking changes
+
+**Warning:** the v0.4 version is a **major break** from v0.3. The core has been rewriten to remove dependency on Kaminari (or WillPaginate).
+
+It also brings a new (more natural) way of defining columns, based on hash definitions (and not arrays) and add some filtering options for column search. [See below](#customize-the-generated-datatables-class) for more infos.
+
+To migrate on the v0.4 you'll need to :
+
+* update your DataTables classes to remove all the `extend` directives
+* switch to hash definitions of `view_columns`
+* update your views to declare your columns bindings ([See here](#wire-up-the-javascript))
+
