Released: https://github.com/bazelbuild/bazel/releases/tag/0.28.0

[jin]

0.28.0 introduced a breaking change with the behavior of --experimental_google_legacy_api.

To reproduce, clone https://github.com/bazelbuild/intellij and run bazel build //aswb:aswb_bazel_zip --define=ij_product=android-studio-beta.

0.28.0:

jingwen@jingwen-sea:~/code/intellij$ USE_BAZEL_VERSION=0.28.0 bazel build //aswb:aswb_bazel_zip --define=ij_product=android-studio-beta --nobuild
ERROR: /usr/local/google/home/jingwen/code/intellij/aspect/intellij_info_impl.bzl:105:25: android_common is experimental and thus unavailable with the current flags. It may be enabled by setting --experimental_google_legacy_api

0.27.2:

This affects all Bazel 0.28.0 users using any of the stable IntelliJ plugins.

cc @c-parsons

78e5fe2 is the breaking change for android_common. We should either rollback this change, or rollforward by whitelisting android_common. It's not feasible to ask all IntelliJ users to add --experimental_google_legacy_api.

I'll take on an action item to expand the IntelliJ CI coverage to ensure that this doesn't happen again: bazelbuild/intellij#977

Update: please cherry pick a0af170 into 0.28.0.

@laurentlb 7d2bc7e caused a bug which was caught internally, 2260b97 is the fix, but it's not in 0.28.0. Please cheery-pick 2260b97 if you're releasing 0.28.1.

Users are starting to report issues with the IntelliJ plugin: bazelbuild/intellij#976 (comment)

Could we expedite promoting 0.28.1rc1 to a release?

The release notes are messed up:

This release contains contributions from many people at Google, as well as .

The sentence is incomplete. Did something go wrong with the release script?

[ulfjack]

The release notes link for 0.28.0 contains a link to the pull request for the release notes, rather than a link to the blog post.

[laurentlb]

Thanks, release descriptions on GitHub have been fixed.
