+
+Incompatible changes:
+
+  - `ctx.resolve_tools` is no longer available by default, in
+    preparation for complete removal. See
+    https://github.com/bazelbuild/bazel/issues/22249 for migration
+    instructions. Use `--noincompatible_disallow_ctx_resolve_tools`
+    to temporarily make it available again.
+  - The `aquery` command now reports all potential inputs of actions
+    that support input discovery, including the input headers of C++
+    compilation actions and those explicitly marked as unused through
+    the `unused_inputs_list` argument to `ctx.actions.run`. Set
+    `--noinclude_pruned_inputs` to omit pruned inputs from `aquery`
+    output when running it after action execution.
+    RELNOTES[INC]: This is not a release note, but a reminder to
+    remove the note for `--include_scheduling_dependencies`, which
+    was introduced in the 8.x tree but won't make it into the final
+    release.
+  - `--zip_undeclared_test_outputs` now defaults to false, causing
+    undeclared test outputs (i.e., files written to
+    `$TEST_UNDECLARED_OUTPUTS_DIR` by a test) to be produced as a
+    directory instead of a zip file.
+
+Important changes:
+
+  - A new experimental flag,
+    `--experimental_build_event_output_group_mode`, allows users to
+    change how a given output group's files are reported in BEP. The
+    current behavior is `FILESET` which populates
+    `OutputGroup.file_sets`. Users may now specify `INLINE` to
+    instead report files directly in the
+    `TargetComplete`/`AspectComplete` event under
+    `OutputGroup.inline_files`. Users may also specify `BOTH` to
+    populate `OutputGroup.file_sets` and `OutputGroup.inline_files`.
+  - Bazel no longer has the android_binary, android_library,
+    android_device_script_fixture and android_host_service_fixture
+    rules. Use https://github.com/bazelbuild/rules_android instead.
+    See https://github.com/bazelbuild/bazel/issues/23199
+  - Bazel no longer has the android_sdk_repository rule. Use
+    https://github.com/bazelbuild/rules_android instead.
+  - Uploading local action results to a disk or remote cache now
+    occurs in the background whenever possible, potentially
+    unblocking the execution of followup actions. Set
+    `--noremote_cache_async` to revert to the previous behavior.
+  - `--incompatible_remote_downloader_send_all_headers` is removed.
+  - `--build_event_upload_max_threads` is removed.
+  - `incompatible_remote_output_paths_relative_to_input_root` is
+    removed.
+  - The default value of
+    `--experimental_remote_cache_compression_threshold` is changed to
+    `100`.
+  - Build without the Bytes is disabled when using HTTP cache.
+  - Build without the Bytes is disabled when using HTTP cache.
+  - Symlink trees are now created through direct filesystem calls by
+    default, instead of delegated to a helper process. On Windows,
+    this entails respecting the `--windows_enable_symlinks` flag,
+    falling back to a copy when the flag is unset (the helper process
+    always attempts to create symlinks, irrespective of the flag).
+    Set `--noexperimental_inprocess_symlink_creation` to temporarily
+    revert to the previous behavior, which will be removed in a
+    future release.
+  - By default, coverage artifacts will be reported inline in the
+    `TargetComplete` event. To disable this behavior, pass
+    `--experimental_build_event_output_group_mode=baseline.lcov=named_
+    set_of_files_only`.
