 <summary><b>2025/06/06 - Version 5.2.0</b></summary>

 [Version 5.2.0 has been released](https://github.com/rules-proto-grpc/rules_proto_grpc/releases/tag/5.2.0),
 which adds support for Scala and Swift languages, updates dependency versions and fixes more bugs. Note
 that using Swift support requires that you use an unreleased version of `rules_swift_package_manager` at
 present.

 </details>

 <details>
 <summary><b>2025/05/16 - Version 5.1.0</b></summary>

 [Version 5.1.0 has been released](https://github.com/rules-proto-grpc/rules_proto_grpc/releases/tag/5.1.0),
 which updates underlying dependency versions and fixes a few key bugs. Note that C language support
 has also been dropped, as the μpb API used was considered unstable and the plugin is no longer
 available outside of the `protobuf` workspace.

 <details open>
 <summary><b>2024/07/31 - Version 5.0.0</b></summary>

 [Version 5.0.0 has been released](https://github.com/rules-proto-grpc/rules_proto_grpc/releases/tag/5.0.0),
 which rewrites the rules to support Bzlmod only. 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 not all languages supported by the 4.x.x
 are supported by this release, with support for the remaining languages being tracked
 [here](https://github.com/rules-proto-grpc/rules_proto_grpc/issues/299). 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. Please see
 [the docs](https://rules-proto-grpc.com/en/latest/) for details of how to migrate your usage to
 these new rules, in particular the
 [release notes](https://rules-proto-grpc.com/en/latest/changelog.html).

	been handed off to Bazel and new versions of gRPC and Protobuf should hopefully be able to be
	supported more rapidly.

	At present not all languages supported by the 4.x.x
	are supported by this release, with support for the remaining languages being tracked
	[here](https://github.com/rules-proto-grpc/rules_proto_grpc/issues/299). 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. Please see
	[the docs](https://rules-proto-grpc.com/en/latest/) for details of how to migrate your usage to
	these new rules, in particular the
	[release notes](https://rules-proto-grpc.com/en/latest/changelog.html).
