Incompatible changes:

  - the --experimental_no_dotd_scanning_with_modules command line
    argument is not supported anymore.
  - The --prune_cpp_modules command line option is not supported
    anymore.
  - the --experimental_prune_cpp_input_discovery command line option
    is not supported anymore.

New features:

  - Added support for Android NDK r18.

Important changes:

  - The 'default' parameter of attr.output and attr.output_list is
    removed. This is controlled by
    --incompatible_no_output_attr_default
  - A number of platform-related Starlark APIs which were previously
    marked "experimental" are now disabled by default, and may be
    enabled via --experimental_platforms_api
  - Make legacy-test-support ("legacy_test-<api-level>") from
    android_sdk_repository neverlink. The legacy test support
    libraries shouldn't be built into test binaries. To make them
    available at runtime, developers should declare them via
    uses-library:
    https://developer.android.com/training/testing/set-up-project#andr
    oid-test-base
  - query remote server Capabilities (per REAPI v2)
  - CppRules: All cc_toolchains depended on from
    cc_toolchain_suite.toolchains are now analyzed when not using
    platforms in order to select the right cc_toolchain.
  - removed obsolete --explicit_jre_deps flag.
  - Incompatible flag
    --incompatible_disable_legacy_cpp_toolchain_skylark_api was
    flipped.
  - Improve error messaging when unsupport proguard options are
    specified at the library level.
  - Incompatible flag
    --incompatible_disable_legacy_cpp_toolchain_skylark_api was
    flipped.
  - Incompatible flag
    --incompatible_disable_legacy_cpp_toolchain_skylark_api was
    flipped.
  - The --incompatible_disable_late_bound_option_defaults flag has
    been flipped (#6384)
  - Incompatible flag
    --incompatible_disable_legacy_flags_cc_toolchain_api was flipped
    (#6434)
  - Fixed issue where ctx.resolve_command created conflicting
    intermediate files when resolve_command was called multiple times
    within the same rule invocation with a long command attribute.
  - Incompatible flag
    --incompatible_disable_cc_configuration_make_variables was
    flipped (#6381)
  - If the --javabase flag is unset, it Bazel locates a JDK using
    the JAVA_HOME environment variable and searching the PATH. If no
    JDK is found --javabase will be empty, and builds targeting Java
    will not
    be supported. Previously Bazel would fall back to using the
    embedded
    JDK as a --javabase, but this is no longer default behaviour. A
    JDK should
    be explicitly installed instead to enable Java development
  - Bazel will now shut down when idle for 5 minutes and the system
    is low on RAM (linux only).
  - CROSSTOOL file is now read from the package of cc_toolchain, not
    from
    the package of cc_toolchain_suite. This is not expected to break
    anybody since
    cc_toolchain_suite and cc_toolchain are commonly in the same
    package.
  - All overrides of Starlark's ctx.new_file function are now
    deprecated.
      Try the `--incompatible_new_actions_api` flag to ensure your
    code is forward-compatible.
  - --incompatible_disable_cc_toolchain_label_from_crosstool_proto
    was flipped.
  - Introduce --(no)shutdown_on_low_sys_mem startup flag to toggle
    idle low-memory shutdown, disabled by default.
  - --incompatible_disable_cc_toolchain_label_from_crosstool_proto
    was flipped.
  - --incompatible_disable_cc_toolchain_label_from_crosstool_proto
    was flipped.
  - CppRules: All cc_toolchains depended on from
    cc_toolchain_suite.toolchains are now analyzed when not using
    platforms in order to select the right cc_toolchain.
  - The function `attr.license` is deprecated and will be removed.
      It can be disabled now with `--incompatible_no_attr_license`.
  - `range()` function now returns a lazy value
    (`--incompatible_range_type` is now set by default).
  - The code coverage report now includes the actual paths to header
    files instead of the ugly,
    Bazel generated, virtual includes path.
  - `--incompatible_disallow_conflicting_providers` has been switched
    to true
  - Add new flag `--incompatible_disable_systool_from_configration` to
    disable loading the systool from CppConfiguration.
  - Add new flag `--incompatible_disable_sysroot_from_configuration`
    to
    disable loading the systool from CppConfiguration.
  - Sorting remote Platform properties for remote execution. May
    affect cache keys!
  - Use different server log files per Bazel server process; java.log
    is
    now a symlink to the latest log.
