bazelbuild/rules_go 0.4.3 on GitHub

Features

Upgraded to Go 1.8.1 and provided backward compatibility for tests in 1.7.5.
Support for build constraints (build tags and filename suffixes) in go_library, cgo_library, go_test, and go_binary. You can now add all your sources to your rules, and they will be filtered during compilation.
- Note: Gazelle also filters sources with build constraints. This behavior will be removed when #339 is fixed.
go_repositories now supports custom Go versions. Versions can be specified with a simple version string (e.g., "1.8.0") or by declaring a separate Bazel repository and providing that through the go_linux or go_darwin attributes.
go_repository now supports vcs and importpath attributes. This enables repositories with different URLs and import paths.
gc_goopts and gc_linkopts attributes can be used to pass additional options to the compiler and linker.
protoc and protoc_gen_go can now be overridden in go_proto_library. Also added an ignore_go_package attribute.
Gazelle now adds a data dependency on testdata directories.

Fixed repositories rules that depended on the real names of repositories. This broke when one of our dependencies (github.com/bazelbuild/buildifier) was renamed to buildtools. A quick fix was backported to 0.4.2 and 0.3.4.
Fixed -mode diff in Gazelle. It now produces a regular textual diff.
Gazelle no longer attempts to rename files with -mode fix or -mode print.
Gazelle can now find # gazelle:ignore comments that aren't at the top of a file.
Bash scripts generated by rules are now executed as commands instead of executable files. This is required on Windows.
Fixed an infinite recursion issue on Windows.
data files are now propagated transitively across dependencies.
