0.9.0

Go rules

• Support for transitive link stamping. You can now set x_defs attributes in go_library rules. Any binary rules that depend on those libraries (directly or transitively) will apply those definitions at link time. See Defines and Stamping for more information.
• Refactored rules and toolchain internals. This doesn't affect normal usage of Go rules, but if you maintain Bazel rules that depend on Go providers and toolchains, see documentation in go/toolchains.rst, especially on GoContext and go_context.
• The library attribute is now deprecated. Please migrate to embed instead. gazelle fix will do this for you automatically.
• Several fixes for cgo, Windows, and ppc64.
• Fixed a bug in the code used to check the minimum Bazel version.

Proto rules

• Support for gogo proto. See GOGO_VARIANTS in proto/BUILD.bazel for available compiler plugins. See gogo/BUILD.bazel for an example.
• Proto files no longer need to set option go_package, and the proto package doesn't need to match the importpath explicitly set in go_proto_library.

Gazelle

Reminder: the old Gazelle tree at go/tools/gazelle is deprecated and will be removed soon (#1199). The new location is github.com/bazelbuild/bazel-gazelle. Please update any tooling you have that builds Gazelle at master.
