[bwappsec]

The upgrade from Vert.x 3.9.12 to 4.5.23 is a major version change with significant breaking changes that require code modifications.

Highlights:

• Asynchronous Operations: Vert.x 4 shifts from callbacks to Futures for asynchronous operations. Many methods that were previously void now return a Future, which is a breaking change for fluent APIs. [1, 4]
• API Removals: Several deprecated APIs from Vert.x 3, particularly in authentication and authorization, have been removed. [4, 12]
• Dependencies: jackson-databind is now an optional dependency and must be explicitly added to your project if you perform JSON object mapping. [1]

Source: Vert.x 3 to 4 Migration Guide
Recommendation: This upgrade requires careful code review and refactoring. Developers must update asynchronous handling to use Futures and verify all authentication/authorization usage against the new APIs.
