bazelbuild/rules_go 0.19.0 on GitHub

Compatibility

The minimum supported version of Bazel is now 0.23.0.

Ubuntu 14.04 is no longer supported.

Changes

When cross-compiling, a C/C++ toolchain is no longer required. Previously, a toolchain was required but usually not used. To cross-compile with cgo, add a _cgo suffix to the target platform. For example, --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64_cgo.
When stamping go_binary and go_tests with the x_defs attribute, the --stamp command-line flag must be used. Without this flag, link stamping is not done. This improves caching of link actions and is consistent with what cc_binary and other native Bazel rules do.
A repository named go_sdk is no longer required. go_register_toolchains will automatically detect any declared SDK workspaces. This simplifies workspaces that use both local and remote execution.
linkmode = "pie" is now supported in go_binary and go_test.
go_library now supports an importpath_aliases attribute that accepts a list of alternative strings that may be used to import the package. This is needed for minimal module compatibility.
Go packages are now built with a single GoCompilePkg action. We no longer use separate actions for compilation, coverage, assembly, packing, etc. cgo code is no longer built with cc_library and custom rules. This should reduce overhead in remote execution configurations.

Deprecations

The objc = True feature is now deprecated. go_library and other rules can now compile .m and .mm files directly when cgo = True is set.
Go 1.10 support is now deprecated.

See Deprecation schedule for more information.

Updated dependencies

bazel_skylib has been updated to 0.8.0.
org_golang_x_tools has been updated to master as of 2019-07-08.
com_github_golang_protobuf has been updated to v1.3.1.
com_github_mwitkow_go_proto_validators has been updated to master as of 2019-07-08.
go_googleapis has been updated to master as of 2019-07-09.

Several workspaces are no longer declared in go_rules_dependencies.

com_google_protobuf is no longer declared. Users of proto_library and go_proto_library must declared it separately in WORKSPACE. Its dependencies must also be declared using its dependency macro, protobuf_deps, declared in @com_google_protobuf//:protobuf_deps.bzl. See Proto dependencies for more information.
org_golang_google_grpc is no longer declared. Recent versions have a large number of dependencies, and we can't realistically manage all of them. It's better to import them as go_repository rules using gazelle update-repos. See gRPC dependencies for more information.
org_golang_x_net, org_golang_x_text, and org_golang_x_sys are no longer declared. They were provided as dependencies of gRPC.
com_github_golang_glog is no longer declared. It was only used in a legacy example.
com_github_kevinburke_go_bindata is now declared in the go_embed_data_dependencies macro in @io_bazel_rules_go//extras:embed_data_deps.bzl. It has been updated to v3.13.0, the latest version as of 2019-07-08.

REMINDER: com_google_protobuf and some other proto repositories are no longer declared in go_rules_dependencies. See Proto dependencies and gRPC dependencies for details.
