Getting "FastifyError [Error]: fastify-plugin: mercurius-validation - expected '4.x' fastify version, '5.0.0' is installed" error when trying to upgrade to fastify v5.0.0

I am trying to upgrade fastify version in my project from 4.28.1 to 5.0.0 but I am getting the mentioned error.

The latest version of mercurius-validation is 5.0.0 which supports fastify 4.28.1
Any idea when you will upgrade mercurius-validation to support fastify 5.x
