5.0.1

Fixed gRPC-Gateway OpenAPI plugin on Linux ARM64 #360

5.0.0

The 5.0.0 release introduces support for Bzlmod and drops support for WORKSPACE. This has required a large restructure of the repo, with the code being split into multiple modules. A 'core' module provides common types and compilation support, whilst per-language modules provide the integration with each language's specific third-party modules and tools. Moving to Bzlmod provides a huge improvement in the stability and maintainability of these rules, as third-party transitive dependency management has been handed off to Bazel and new versions of gRPC and Protobuf should hopefully be able to be supported more rapidly.

At present, a limited number of languages have been migrated from the 4.x.x releases, with support for the remaining languages being tracked here. For these unsupported languages - or for WORKSPACE repos - it is recommended you continue using the 4.x.x releases.

The way you use these rules is largely unchanged, but unfortunately the paths used for load of the rules will have changed due to the splitting into language-specific modules. For example, the following load:

load("@rules_proto_grpc//go:defs.bzl", "go_proto_library")

Will become:

load("@rules_proto_grpc_go//:defs.bzl", "go_proto_library")

Details on the new rule loads can, as always, be found on each language's page in the documentation. Examples for each language are also provided in the repo's examples directory.

Some key other changes include:

• The versions of gRPC and Protobuf are updated to the latest available in
  Bazel Central Registry
• Python now pulls gRPC and Protobuf from pip wheels
• Buf rules now work on Windows (requires the --enable_runfiles flag to be set)

Should you have any issues with the new release, please open a new issue or discussion.
