Release Notes

bazelbuild/rules_go

v0.21.0

Compare Source

Compatibility

• The minimum supported version of Bazel is now 1.2.0 (was 0.23.0). Some of our dependencies are no longer compatible with old versions of Bazel, so we needed to drop some support.
• The go_rule wrapper function is now deprecated, since it doesn't work well after some Bazel compatibility changes in 2.0.0. See the deprecation schedule for rationale and migration information. In general, we're evaluating a change to the way we handle toolchains and flags in order to better support configurations. If you have custom rules declared with go_rule or go_context or if you use custom toolchains compatible with go_toolchain, please reach out via go-bazel-discuss or on the #bazel channel on Gophers Slack.

This release contains no significant user facing changes. Several bugs are fixed, and dependencies are updated. Compatibility with Bazel 2.0.0 and later versions is improved.

Hi @renovate-bot. Thanks for your PR.

I'm waiting for a bazelbuild member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
