Fastify Now Speaks OpenAPI 3.2

The OpenAPI Initiative announced OpenAPI 3.2 on September 23rd, 2025. Almost exactly a year later, on September 22nd, the Fastify project shipped fastify-swagger v9.9.0, and its release notes are a single line: OpenAPI 3.2.0 compatibility. It is a small release, but it is the kind I pay attention to, because a specification version only becomes real when the tools that generate contracts can produce it.
