This upgrade from Rails 3.1 to 5.0 is a major undertaking with significant breaking changes across the framework and its dependencies. It requires a new version of Ruby, introduces a completely new model for handling controller parameters (Strong Parameters), and overhauls the asset pipeline. Key features from Rails 3 have been extracted into separate gems, and many deprecated methods have been removed.

Top Breaking Changes:

• Rails 3.1.0 → 5.0.0 (High): This is a multi-version leap requiring significant code and configuration updates. Key breaking changes include the replacement of attr_accessible with Strong Parameters, the extraction of features like ActiveResource and page/action caching into gems, and a required Ruby version of 2.2.2+. Models will now inherit from ApplicationRecord instead of ActiveRecord::Base. Callback chains are no longer halted by returning false and must explicitly use throw(:abort).
• sass-rails 3.1.3 → 5.0.5 (High): The upgrade to version 5.0 makes sassc-rails the new underlying implementation, which may introduce subtle compilation differences. More importantly, it deprecates the use of .css.scss and .css.sass file extensions, requiring file renames.
• jquery-rails 1.0.14 → 4.0.1 (Medium): This major version bump primarily updates the version of the jQuery library itself. The underlying jQuery 4.0 removes support for IE versions below 11, removes several deprecated APIs like jQuery.isArray and jQuery.parseJSON, and changes the event order for focusin and focusout.

Other Upgrades:

• coffee-rails 3.1.1 → 4.1.1 (Low): This upgrade aligns the gem with Rails 4+ and the corresponding changes in the asset pipeline. No major breaking API changes are cited, but it's part of the larger asset pipeline overhaul.

Recommendation: This is a complex migration that should be handled incrementally. First, upgrade Rails from 3.1 to 3.2, then to 4.0, 4.1, 4.2, and finally 5.0, addressing deprecation warnings at each step. A comprehensive test suite is essential before starting. Pay close attention to the move from attr_accessible to Strong Parameters and the necessary updates to the asset pipeline gems.
