Changes in this release

Major features in this release include:

• The ability to auto-generate the x-nullable field from proto3 optional in openapiv2 contributed by Ken Brownfield (@irridia) in #2215
• More comprehensive openapiv2 name generation options contributed by @alperengozeten and Malte Isberner (@misberner) in #2310

As well as various bug fixes, including the auto generation of the Www-Authenticate header when returning an 401 Unauthorized error (#2314), better google.protobuf.Any representation in openapiv2 files (#2292) and much more.

This is also the first release to automatically publish the Protobuf plugins to the Buf Schema Registry. See https://buf.build/grpc-ecosystem/plugins. These can be used together with the new buf generate remote plugins feature: https://docs.buf.build/configuration/v1/buf-gen-yaml#name-or-remote. An example buf.gen.yaml using these new plugins looks like this:

version: v1
plugins:
  - remote: buf.build/library/plugins/go:v1.27.1-1
    out: gen/go
    opt: paths=source_relative
  - remote: buf.build/library/plugins/go-grpc:v1.1.0-2
    out: gen/go
    opt: paths=source_relative
  - remote: buf.build/grpc-ecosystem/plugins/grpc-gateway:v2.6.0-1
    out: gen/go
    opt: paths=source_relative
  - remote: buf.build/grpc-ecosystem/plugins/openapiv2:v2.6.0-1
