This is a very large upgrade, jumping from version 1.4.6 to 4.2.0 across multiple major versions (2.x, 3.x, 4.x). It introduces significant breaking changes that will require code and environment updates.

Highlights:

• Ruby & Rack Upgrade: The minimum required Ruby version is now 2.7.8, and the Rack dependency has been upgraded from ~1.4 to 3.x. Rack 3 contains its own set of breaking changes, such as moving session middleware, which will likely require code modifications. [16, 17, 19]
• Default Server Change: The default web server has been changed from Thin to Puma as of version 4.0.0. [5]
• Removed Template Engines: Support for CoffeeScript, Mediawiki, Creole, Radius, and the Less templating library was removed in version 3.0.0. [4]

Source: Sinatra CHANGELOG
Recommendation: This upgrade will likely require significant code refactoring and dependency updates. Thoroughly test your application against the new Rack version and ensure your deployment environment is configured for the Puma web server if you rely on the default.
