     Automated rollback of commit
     5576979669383c2380c11b59beaa2f8263ff1f56.

Incompatible changes:

  - this incompatible change breaks old instances of http_archive
    that specified netrc as an absolute path. It is unlikely there
    are many instances in the wild since the path would refer to a
    netrc file inside the external repository by absolute path.
    Migration should be straightforward.
  - genrule switched to use exec transition instead of host. This can
    break targets with hardcoded output paths. To avoid using
    hardcoded paths use make variables, see
    https://docs.bazel.build/versions/4.2.2/be/make-variables.html#pre
    defined_label_variables

  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - Error Prone now checks for unused return values of additional

    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - The --incompatible_existing_rules_immutable_view flag has been
    flipped to true. See
    https://github.com/bazelbuild/bazel/issues/13907 for
    migration notes.

Important changes:

  - Deprecate --incompatible_applicable_licenses flag, in preparation
    for removal in Bazel 6.x.
  - Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
  - The Build Event Protocol now contains file digests and sizes
    along with the file name and URI.
  - Refactor system suspend event handling.
  - alias() can now select() directly on constraint_value()
  - Allow \a \b \f \v escape sequences in Starlark.
  - Match remote and local xcode version by most granular version.
  - Adds `--experimental_worker_multiplex_sandboxing` flag that
    controls whether to sandbox multiplex workers that support it.
  - provider() has a new parameter: init, a callback for performing
    pre-processing and validation of field values. Iff this parameter
    is set,
    provider() returns a tuple of 2 elements: the usual provider
    symbol (which,
    when called, invokes init) and a raw constructor (which bypasses
    init).
  - Tests that fail to create or complete their
    `TestAttemptContinuation` by
    throwing an `ExecException` will report an `INCOMPLETE` status.
    Previously, Bazel
    would fail to report any status for the test attempt.
  - Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
  - Include more information about configurations in cquery proto
    formatted output. This deprecates the configuration field of
    AnalysisProtosV2.ConfiguredTarget, and adds a new field,
    configuration_id, to
    be used instead.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - In aquery and cquery proto output, indicate if a configuration is
    a
    tool or non-tool configuration.
  - Include complete configurations in cquery proto output.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - Make protocOpts() publicly accessible.
  - Add some documentation about how configuration information is
    conveyed in cquery proto output.
  - Introduces experimental static library linking API under
    apple_common.link_multi_arch_static_library
  - Further deprecation and removal of pkg_tar. Stop supporting
    legacy use of 'files' attribute, where it could be a list of
    labels instead of a map of paths to labels.
  - Removed --incompatible_no_build_defs_pkg flag. It never fulfilled
    its purpose because --all_incompatible_changes would never set
    it. The last rule it gated (pkg_tar) is scheduled to be removed
    in Bazel 6.x.
  - Add coverage configuration fragment, used to expose
    output_generator label.
  - Bazel now no longer includes system headers on macOS in coverage
    reports (#14969).
