Faker is a well-known and powerful library for generating fake data. It provides a wide range of random but realistic-looking data generators. However, testing with purely random data can be risky, which is why property-based testing is valuable. While using fake but realistic data in tests can be beneficial, it is essential to integrate it properly. fast-check offers a robust solution for this integration.

This release introduces new arbitraries to enhance shrinking capabilities and deprecates the noShrink and noBias methods in favor of these new arbitraries.
