Improving the health of Bazel’s orphaned issues and PRs

Over the past few years, we have noticed several languishing issues and pull requests on repositories across the Bazel GitHub organization. While some have stalled without updates from authors, others have languished due to limited bandwidth and resources on the Bazel team’s end. In late 2022, we prioritized an effort to periodically review old issues/PRs and close them out as needed. Our apologies for the late communication on this process.

GitHub Archive Checksum Outage

On 2023-01-30, many Bazel users encountered build errors due to a change in GitHub's source archive generation mechanism. The change, since rolled back, caused all source archives (not release archives) to have a different checksum, despite their contents being unchanged. This caused an outage for several package management systems that relied on stable checksums, including Bazel.
