This is a very large major version upgrade, spanning from Rails 3.0 to 5.0. It includes multiple fundamental architectural changes and requires a careful, staged migration. Key breaking changes include the replacement of attr_accessible with Strong Parameters and a change in how ActiveRecord callbacks are handled.

Highlights:

• Replace attr_accessible: The mass-assignment protection provided by attr_accessible in models is removed. It must be replaced with Strong Parameters, where permitted parameters are explicitly defined in the controller.
• Update ActiveRecord Callbacks: In Rails 5, before_* callbacks no longer halt execution when they return false. The callback chain must now be explicitly stopped by using throw(:abort).

Source: Package documentation
Recommendation: Do not merge directly. A sequential upgrade following the official Rails migration guides (3.0 → 3.1 → 3.2 → 4.0 → 4.1 → 4.2 → 5.0) is required.
