This is a major upgrade from Vert.x 3 to Vert.x 4, which introduces significant breaking changes across the entire Vert.x stack.

Highlights:

• Asynchronous Programming Model: Vert.x 4 adopts a Future-first approach for asynchronous operations, moving away from the traditional callback-style APIs. For example, eventBus.send() with a reply handler is replaced by eventBus.request() which returns a Future. [1, 2]
• API Removals and Modifications: Many APIs deprecated in version 3 have been removed. Key changes include WriteStream methods no longer being fluent, MessageProducer no longer extending WriteStream, and the removal of the Starter class in favor of Launcher. [1, 2]

These core changes impact all other Vert.x modules, including vertx-web, vertx-lang-kotlin, and vertx-service-proxy, requiring code modifications.

Source: Eclipse Vert.x 4.0 Migration Guide
Recommendation: This upgrade requires significant refactoring. Developers must carefully follow the official migration guide to adapt the application to the new APIs and asynchronous model. [1, 2, 6]
