Changes

No major changes, only version updates

Version Updates

• Updated Bazel buildifier_prebuilt to 8.2.0.2
• Updated Bazel gazelle to 0.44.0
• Updated Bazel rules_cc to 0.1.2
• Updated Bazel rules_go to 0.55.1
• Updated Bazel rules_shell to 0.5.0
• Updated Bazel rules_swift to 3.0.2
• Updated Bazel rules_swift_package_manager to 1.0.0
• Updated Swift grpc/grpc-swift to 2.2.3
• Updated Swift grpc/grpc-swift-protobuf to 1.3.1

5.2.0

Changes

• Restored Scala language support
• Restored Swift langauge support
• Fixed usage of options attr on Bazel 8, where the Label canonicalisation has changed
• Fixed loading of Buf protoc lint plugin
• Fixed loading of Buf protoc breaking plugin on linux/arm64
• Switched gRPC-Gateway to be loaded directly from Bazel bzlmod dependency rather than via Go/Gazelle
• The gateway_openapiv2_compile() rule now uses a directory as output, to allow creating a combined output file. #382
• Fixed bzl_library referencing incorrect dependency in @protobuf
• Switched from @bazel_tool//platforms to @platforms
• The Python dependencies for Protobuf and gRPC are now loaded from the @protobuf and @grpc bzlmod workspaces respectively, rather than from PyPI wheels. This is necessary to prevent version skew between the protoc version and the runtime version, but unfortunately may result in longer uncached build times
• Added CI testing on MacOS (x64 and arm)

Version Updates

• Updated Bazel protobuf to 31.1
• Updated Bazel rules_go to 0.55.0
• Updated Bazel rules_java to 8.11.0
• Updated Bazel toolchains_protoc to 0.4.2
• Updated Java com.google.protobuf:protobuf-java to 4.31.1

5.1.0

Changes

• Added support for Bazel 8 and dropped Bazel 6 support
• Replaced deprecated rules_proto with protobuf
• Added support for providing extra plugins to rules at runtime using the extra_plugins attribute
• Fixed version skew between grpc-gateway protoc plugin and runtime
• Added optional generation of .pyi files for Python
• Switched Objective-C sources to use non_arc_srcs
• Dropped C language support, as the μpb API is considered unstable and the C plugin is no longer publicly visible from the protobuf workspace
• Removed usage of ctx.resolve_tools that is deprecated
• Added Python 3.13 to supported list
• Replaced custom grpclib plugin with py_console_script_binary

Version Updates

• Updated Bazel apple_support to 1.22.0

• Updated Bazel rules_python to 1.4.1
• Updated Bazel rules_shell to 0.4.1

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.

5.0.0-alpha3

• Fixing the generated python path with dot
• Set cfg = exec on plugins label list template
• Correctly forward test attrs for buf test rules

5.0.0-alpha2

Accept release version number from input

5.0.0-alpha1

Test first release of bzlmod rules for rules_proto_grpc

4.6.0

General

• Fixed incompatibility with Bazel 7 for the C, C++ and Objective-C rules. #298

Rust

• Breaking change: The preserve_proto_field_names option is no longer set on the Serde plugin by default, as it cannot then be disabled. If you need this option, set if manually with the options attr. #297
• Disabled Clippy lints in generated code. #296
