-6.0.1 (2025-03-28)

-
-Same as v6.0.0.
-
-Due to a problem tag v6.0.0 was replaced. This isn't a good practice and affect
-developers that started using it in the short timeframe. Submitting a new
-release with the same content is the best way to fix this.

-See #1017 and #1019.

   - See `selectionStyleReset` decorator.
 - Breaking change: Change how "focus"/"select" are handled. This fixes the
   behavior.
-- Breaking change: `Component::OnRender()` becomes the method to override to
-  render a component. This replaces `Component::Render()` that is still in use
-  to call the rendering method on the children. This change allows to fix a
-  couple of issues around focus handling.
 
 ### Screen
 - Feature: Add `Box::IsEmpty()`.
