-     Fix terrible ForkJoinQuiescingExecutor latent bug exposed by new
-     usage of ForkJoinPool: only "adapt" a runnable to run in an
-     existing FJP if that existing FJP is the same as the executor's:
-     don't enqueue them to run in whatever random FJP is trying to
-     enqueue this runnable. Big props to michajlo@ for quickly
-     diagnosing this and suggesting the fix.

 Incompatible changes:
 
+  - Removing java_common.javac_jar Starlark call.
+  - native.existing_rule now returns select values in a form that is
+    accepted by rule instantiation. This is a breaking API change
+    because there is some code that relies on the precise type
+    returned, including brittle workarounds for this bug specifically
+    and insufficiently flexible workarounds for other issues with the
+    intersection of select and native.existing_rule.
+  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
+    #7849
+  - Query output=xml/proto/location for source files will now show
+    the location of line 1 of the source file (as the new default)
+    instead of its location in the BUILD file.
+  - Specifying a target pattern underneath a directory specified by
+    .bazelignore will now emit a warning, not an error.
+  - Query `--order_output=auto` will now sort lexicographically.
+    However, when `somepath` is used as a top level function (e.g.
+    `query 'somepath(a, b)'`), it will continue to output in
+    dependency order. If you do not want the lexicographical output
+    ordering, specify another `--order_output` value (`no`, `deps` or
+    `full`) based on what ordering you require.
+  - In the build event stream,
+    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
+    Its value was always mostly meaningless.
+    BuildMetrics.TargetMetrics.targets_configured and
+    BuildMetrics.ActionSummary.actions_created now include configured
+    aspect data.
+  - //visibility:legacy_public has been removed.
+  - Flip and remove incompatible_dont_collect_so_artifacts
+    (https://github.com/bazelbuild/bazel/issues/13043).
+  - Remove flag --experimental_no_product_name_out_symlink: it is
+    always true.
+  - The Starlark method generate_dsym in objc fragment has
+    been deleted.  Please use the equivalent apple_generate_dsym in
+    cpp
+    fragment instead.
+  - Native libraries in data attribute are not collected. See
+    https://github.com/bazelbuild/bazel/issues/13550 for details
+  - Enforce the `--profile` path to be absolute.
+  - Enforce the --memory_profile path to be absolute.
+  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
+  - --apple_sdk has been deleted.  It is a no-op.
   - --bep_publish_used_heap_size_post_build is now a no-op and will
     be deleted in a future release. Use --memory_profile=/dev/null
     instead.
+  - Flipped --incompatible_disallow_resource_jars (see
+    https://github.com/bazelbuild/bazel/issues/13221).

+Important changes:
+
+  - Flag --incompatible_objc_compile_info_migration is removed.  See
+    #10854.
+  - Flag --incompatible_objc_compile_info_migration is removed.  See
+    #10854.
+  - Flag --incompatible_objc_compile_info_migration is removed.  See
+    #10854.
+  - none
+    PAIR=cmita
+  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
+  - Filter all (instead of just C++) source files for coverage output
+    according to --instrumentation_filter and
+    --instrument_test_targets.
+  - The `--incompatible_disable_native_apple_binary_rule` flag has
+    been added which disables the native `apple_binary` rule. Users
+    who need to use `apple_binary` directly (if they cannot use one
+    of the more specific Apple rules) should load it from
+    https://github.com/bazelbuild/rules_apple.
+  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
+    SingleJar will always be used to build APKs.
+  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
+    already contains key. This is an incompatible API change.
+  - Flag --incompatible_objc_provider_remove_compile_info is removed.
+     See #11359.
+  - Starlark now permits def statements to be nested (closures).
+  - native.existing_rule now returns select values in a form that is
+    accepted by rule instantiation. This is a breaking API change,
+    though the fallout is expected to be small.
+  - Starlark now supports lambda (anonymous function) expressions.
+  - The "test" and "coverage" commands no longer return 3 when a
+    test action fails because of a system error. Instead, the exit
+    code
+    reflects the type of system error.
+  - The undocumented ctx.expand feature no longer exists.
+  - Make --legacy_dynamic_scheduler a no-op flag.
+  - Multiplex persistent workers can now use the JSON protocol.
+  - native.existing_rule now returns a mutable list, not a tuple, for
+    a list-valued attributes. This is an incompatible API change.
+  - Roll back change to have native.existing_rules use list instead
+    of tuple.
+  - BEP includes test suite expansions.
+  - config_setting now honors `visibility` attribute (and defaults to
+    `//visibility:public`)
+  - Change the MultiArchSplitTransitionProvider to be based on
+    platform type + CPU instead of fixed "ios_" + cpu.
+  - enforce config_setting visibility. See
+    https://github.com/bazelbuild/bazel/issues/12932 for details.
+  - add a flag to build v4 signature file
+  - Added _direct_source_jars output group to Java related targets.
+    END_PUBLIC
+  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
+    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
+  - Allowing the lipo operations to be conditional in the
+    linkMultiArchBinary API for Apple binaries. Single architecture
+    slices are now returned through AppleBinaryOutput and the
+    Starlark API.
+  - Release restriction for "-" in the package name for Python
+    sources. Now `py_binary` and `py_test` targets can have main
+    source file with "-" in the path.
+  - Users consuming BEP may assume that a `named_set_of_files` event
+    will
+    appear before any event referencing that `named_set` by ID. This
+    allows consumers
+    to process the files for such events (eg. `TargetCompleted`)
+    immediately.
+  - BEP includes all files from successful actions in requested
+    output groups.
+    Previously, an output group's files were excluded if any file in
+    the output group
+    was not produced due to a failing action. Users can expect BEP
+    output to be larger
+    for failed builds.
+  - In BEP, TargetComplete.output_group has a new field `incomplete`
+    indicating that the file_sets field is missing one or more
+    declared artifacts
+    whose generating actions failed.
+  - The flag `--toolchain_resolution_debug` now takes a regex
+    argument, which is used to check which toolchain types should
+    have debug info printed. You may use `.*` as an argument to keep
+    the current behavior of debugging every toolchain type.
+  - Add runfiles.merge_all() for merging a sequence of runfiles
+    objects.
+  - runfiles.merge() and merge_all() now respect
+    --nested_set_depth_limit.
+    If you hit the depth limit because you were calling merge() in a
+    loop, use
+    merge_all() on a sequence of runfiles objects instead.
+  - Bazel will no longer create a bazel-out symlink if
+    --symlink_prefix is specified: the directory pointed to via the
+    bazel-out symlink is accessible via ${symlink_prefix}-out. If
+    this causes problems for you, set
+    --experimental_no_product_name_out_symlink=false in your builds
+    and file an issue.
+  - Updates worker protocol with cancellation fields, and adds
+    experimental_worker_cancellation flag to control cancellation.
+  - Simplify build failure output by always using `NNN arguments`.
+  - trim_test_configuration now defaults to on
+  - Mark genrule.srcs as a source attribute for coverage.
+  - When using --allow_analysis_failures (for example, via
+    bazel-skylib's
+    analysistest with `expect_failure = True`), analysis-time
+    failures in aspect
+    implementation functions will now be propagated and saved in
+    AnalysisFailureInfo, just like analysis-time failures in rules.
+  - cquery --noimplicit_deps now correctly filters out resolved
+    cc_toolchains
+  - Sign apks deterministically.
+  - Make gcov optional in cc_toolchain tools.
+  - If --experimental_prefer_mutual_xcode is passed, Bazel will
+    choose the local default (instead of the newest mutually
+    available version) if it's available both locally and remotely.
+  - Remove java_lite_proto_library.strict_deps attribute.
+  - Generate proguard configurations deterministically.
+  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
+    switches from the use of build variables to the feature of the
+    same name.
+  - Dropped fragile xz support from built in pkg_tar. Users requiring
+    xz
+    compression should switch to bazlebuild/rules_pkg.
+  - If all strategies of one branch (the local or remote execution
+    branch) of the `dynamic` strategy fail to even accept (via the
+    response they give from `canExec`) the action, `dynamic` will now
+    try to see if the other branch can accept it. (Trying to run it
+    and it failing will still cause a failure if it was the first
+    result, this is about strategies claiming they can't even try the
+    action)
+  - Add `disable_annotation_processing` option to
+    `java_common.compile`, which disables any annotation processors
+    passed to `plugins` or in `exported_plugins` of `deps`
+  - Remove obsolete --incompatible_prohibit_aapt1
+  - The minimum Android build tools version for the Android rules is
+    now 30.0.0
+  - Adds --experimental_reuse_sandbox_directories flag to reuse
+    already-created non-worker sandboxes with cleanup.
+  - --experimental_force_gc_after_build is deprecated and will be
+    removed soon. Use --bep_publish_used_heap_size_post_build instead
+  - Forward coverage-instrumented files from non-tool dependencies by
+    default.
+  - The used_heap_size_post_build field in BEP is populated when the
+    --memory_profile flag is set
+  - --run_validations defaults to true.
+  - Consider label_keyed_string_dict attributes when gathering
+    instrumented files for coverage.
+  - Remove flag
+    --experimental_forward_instrumented_files_info_by_default, now
+    that this behavior is the default.
+  - When using MemoryProfiler with multiple GCs via the
+    --memory_profile_stable_heap_parameters flag, we do a more
+    precise calculation of heap used at the end of the build. This
+    will generally result in lower values.
+  - --bep_publish_used_heap_size_post_build is deprecated. Use
+    --memory_profile=/dev/null instead.
+  - Disable --all_incompatible_changes flag.

+
+Important changes:
+
+  - Multiplex persistent workers can now use the JSON protocol.
+  - enforce config_setting visibility. See
+    https://github.com/bazelbuild/bazel/issues/12932 for details.
+  - The minimum Android build tools version for the Android rules is
+    now 30.0.0
+  - Updates worker protocol with cancellation fields, and adds
+    experimental_worker_cancellation flag to control cancellation.
+  - If all strategies of one branch (the local or remote execution
+    branch) of the `dynamic` strategy fail to even accept (via the
+    response they give from `canExec`) the action, `dynamic` will now
+    try to see if the other branch can accept it. (Trying to run it
+    and it failing will still cause a failure if it was the first
+    result, this is about strategies claiming they can't even try the
+    action)
