+- **make:cell** When creating a new cell, the controller would always have the ``Cell`` suffixed to the class name.
+    For the view file, the final ``_cell`` is always removed.
+- **Cells** For compatibility with previous versions, view filenames ending with ``_cell`` can still be

 Bugs Fixed

 - **Validation:** Fixed a bug where a closure used in combination with ``permit_empty`` or ``if_exist`` rules was causing an error.
+- **make:cell** Fixed generating view files as classes.
+- **make:cell** Fixed treatment of single word class input for case-insensitive OS.
