Incompatible changes:

  - Add --incompatible_disallow_legacy_javainfo flag.
  - Added flag --incompatible_disallow_old_style_args_add to help
    migrate from args.add() to args.add_all() / args.add_joined()
    where appropriate.

New features:

  - Bash,runfiles: use the new platform-independent library in
    `@bazel_tools//tools/bash/runfiles` to access runfiles
    (data-dependencies). See
    https://github.com/bazelbuild/bazel/blob/master/tools/bash/runfile
    s/runfiles.bash for usage information.
  - TemplateVariableInfo can now be constructed from Skylark.
  - The java_host_runtime_alias rule is now implemented in Java.

Important changes:

  - Flip default value of --experimental_shortened_obj_file_path to
    true, Bazel now generates short object file path by default.
  - Introduce fdo_profile rule that allows architecture-sensitive
    specification of fdo profiles.
  - canonicalize-flags no longer reorders the flags
  - CppRules: optional_compiler_flag was removed from CROSSTOOL, use
    features instead.
  - Labels of the form ////foo are disallowed.
  - The `/` operator is deprecated in favor of `//` (floor integer
    division).
      Try the `--incompatible_disallow_slash_operator` flag to ensure
    your code
      is forward-compatible.
  - Flip default value of --experimental_shortened_obj_file_path to
    true, Bazel now generates short object file path by default.
  - Exposed "mnemonic" and "env" fields on skylark "Action" objects.
  - Removed flag `--incompatible_disallow_toplevel_if_statement`.
  - Remove vestigial 'deps' and 'data' attributes from
    proto_lang_toolchain
  - Args objects (ctx.actions.args()) have new methods add_all() and
    add_joined() for building command lines using depsets.
  - `FileType` is deprecated and will be removed soon.
      Try the `--incompatible_disallow_filetype` flag to ensure your
    code
      is forward-compatible.
  - Introduce absolute_path_profile attribute that allows fdo_profile
    to accept absolute paths.
  - Support two-arg overloads for ctx.actions.args (eg.
    args.add("--foo", val))
  - Introduce 'tools' attribute to ctx.actions.run.
  - Fixed error message for proguard_apply_dictionary.
  - "bazel run" now lets one run interactive binaries. The
    BUILD_WORKSPACE_DIRECTORY and BUILD_WORKING_DIRECTORY environment
    variables indicate the working directory and the workspace root
    of the Bazel invocation. Tests are provided with an approximation
    of the official test environment.
  - repository rules are no longer restricted to return None.
  - Add --high_priority_workers flag.
  - CppRules: Feature configuration can be created from Skylark
  - Adds new-style JavaInfo provider constructor.
  - Make java_common.compile now uses java_toolchain javacopts by
    default; explicitly retrieving them using
    java_common.default_javac_opts is unnecessary.
  - CppRules: C++ command lines and env variables for C++ actions can
    be retrieved from feature configuration.
  - Skylark rule definitions may advertise providers that targets of
    the rule must propagate.
  - Bazel now supports running actions inside Docker containers.
    To use this feature, run "bazel build --spawn_strategy=docker
    --experimental_docker_image=myimage:latest".
  - Remote execution works for Windows binaries with launchers.
  - Fixing start/end lib expansion for linking. There were many cases
    where archive files were still being used with toolchains that
    support start/end lib. This change consolidates the places that
    make that decision so they can be more consistent.
  - Add support for reporting an error if
    android_test.binary_under_test contains incompatible versions of
    deps
  - We replaced the --experimental_local_disk_cache and
    --experimental_local_disk_cache_path flags into a single
    --disk_cache flag. Additionally, Bazel now tries to create the disk cache
    directory if it doesn't exist.
  - Save Blaze memory by not storing LinkerInput objects in
    LinkCommandLine
  - In the JavaInfo created by java_common.create_provider now
    includes both direct and transitive arguments in
    transitive_compile_time_jars and transitive_runtime_jars
  - Allow --worker_max_instances to take MnemonicName=value to
    specify max for each worker.
  - Allow java_toolchain.header_compiler to be an arbitrary executable

    favor of
      functions `package_name()` and `repository_name()`.

    https://docs.bazel.build/versions/master/skylark/lib/native.html#p
    ackage_name
  - BUILD_TIMESTAMP now contains seconds (and not milliseconds) since
    the epoch.

New features:

  - The 'j2objc' configuration fragment is exposed to Skylark.
  - Remove the default content of the global bazelrc.
  - In int() function, do not auto-detect base if input starts with
    '0'.
  - Users can now pass --experimental_shortened_obj_file_path=true to
    have a shorter object file path, the object file paths (and all
    other related paths) will be constructed as following:
    If there's no two or more source files with the same base name:

    <bazel-bin>/<target_package_path>/_objs/<target_name>/<source_base
    _name>.<extension>
    otherwise:

    <bazel-bin>/<target_package_path>/_objs/<target_name>/N/<source_ba
    se_name>.<extension>
      N = the file?s order among the source files with the same
    basename, starts from 0.
  - Move (c/cxx)opts from legacy_compile_flags to user_compile_flags
  - CppRules: Remove optional_*_flag fields from CROSSTOOL, they are
    not
    used, and could be expressed using features.
  - Introduce --incompatible_disable_objc_provider_resources to turn
    off all resource-related fields of the Objc provider.
  - Removed the statement of "What does Bazel support?" as it's
    limiting/misleading. Added supported host OSes to
    "multi-platform" paragraph.
  - android_library AAR output now contains proguard.txt
  - Bazel now displays information about remote cache hits and
    execution strategies used in its UI after every build and test,
    and adds a corresponding line "process stats" to BuildToolLogs in
    BEP.
  - Print correct build result for builds with --aspects flag.
  - android_binary.manifest_merger is no longer supported.

    interactive binaries.
  - "blaze run --direct_run" with tests now gives the test an
    approximation of the official test environment.

  - Updated default android_cpu value to armeabi-v7a
  - In skylark, print(target) now shows the provider keys of a
    target, as debug information.

    with the C++11 standard, and
    `--android_crosstool_top=@androidndk//:toolchain-libcpp` to use
    the `libc++` STL.

Incompatible changes:

  - In order to access the template variables $(JAVA) and
    $(JAVABASE), @bazel_tools//tools/jdk:current_java_runtime needs
    to be added to the toolchains= attribute from now on.
  - The ctx.middle_man function is not supported anymore.
  - The flag --incompatible_list_plus_equals_inplace is removed, its
    default behavior is preserved. += on lists now always mutates the
    left hand
    side.
  - --android_sdk no longer supports filegroup targets.

New features:

  - query: Add option --noproto:flatten_selects to turn off
    flattening of selector lists in proto output.
  - New android test rule, android_local_test.

Important changes:

  - The --remote_rest_cache flag now respects --remote_timeout.
  - --experimental_java_coverage is available for testing.
  - The deprecated builtin `set` is no longer allowed even from within
    unexecuted code in bzl files. It's temporarily possible to use
    --incompatible_disallow_uncalled_set_constructor=false if this
    change causes
    incompatibility issues.
  - Linkstamping is now a separate and full-blown CppCompileAction,
    it's
    no longer a part of linking command.
  - Using `+`, `|` or `.union` on depsets is now deprecated. Please
    use the new
      constructor instead (see
    https://docs.bazel.build/versions/master/skylark/depsets.html).
  - config_feature_flag's default_value is optional. It is
    only an error to have a config_feature_flag with no default_value
    if that config_feature_flag has not been set in the configuration
    it is being evaluated in.
  - --[no]keep_incrementality_data is gone, replaced by the
    enum-valued --incremental_state_retention_strategy
  - Linkstamping is now a separate and full-blown CppCompileAction,
    it's
    no longer a part of linking command.
  - Added --checkHashMismatch flag to ZipFilterAction. Valid values
    are IGNORE, WARN and ERROR. --errorOnHashMismatch is deprecated,
    please use this flag instead.
  - Set build jobs equivalent to number of logical processors by
    default. Should improve build times significantly.
  - Added --(no)expand_test_suites flag.
  - Rename --keep_incrementality_data to --track_incremental_state
  - --remote_rest_cache was renamed to --remote_http_cache. Both
    options keep working in this release, but --remote_rest_cache
    will be
    removed in the next release.
  - Aspects-on-aspect see and propagate over aspect attributes.
  - --auth_* flags were renamed to --google_* flags. The old names
    will continue to work for this release but will be removed in the
    next
    release.
  - Remote Caching and Execution support output directories.
  - Remove defunct flags
    --experimental_incremental_dexing_for_lite_proto and
    --experimental_incremental_dexing_error_on_missed_jars that have

Incompatible changes:

  - The deprecated `set` constructor is removed, along with the
    migration flag --incompatible_disallow_set_constructor. It is
    still temporarily
    allowed to refer to `set` from within unexecuted code.
  - The flag --incompatible_disallow_set_constructor is no longer
    available, the deprecated `set` constructor is not available
    anymore.
  - The path to the JVM executable is not accessible anymore as
    ctx.{fragments,host_fragments}.jvm.java_executable. Use
    JavaRuntimeInfo.java_executable_exec_path instead.
  - --clean_style is no longer an option.

New features:

  - Users can use win_def_file attribute to specify a DEF file for
    exporting symbols when build a shared library on Windows.
  - Add --experimental_android_resource_cycle_shrinking option to
    allow for more aggressive code and resource shrinking.

Important changes:

  - Late-bound attributes are exposed to skylark. This is a new API
    (`configuration_field()`) to depend on certain
    configuration-defined targets from skylark rules.
  - Document interaction between test_suite and target exclusions
  - AAR manifest files will come from the processed resource APK if it
    exists.
    RELNOTES: None for Blaze users.
  - Document interaction between test_suite and target exclusions
  - --keep_incrementality_data flag allows Bazel servers to be run in
    memory-saving non-incremental mode independent of --batch and
    --discard_analysis_cache.
  - Add deps attribute to Skylark maven_aar and maven_jar workspace
    rules.
  - Use --expand_configs_in_place as a startup argument to change the
    order in which --config expansions are interpreted.
  - SOURCE_DATE_EPOCH
    (https://reproducible-builds.org/specs/source-date-epoch/) can
    be used to override the timestamp used for stamped target (when
    using --stamp).
  - Package specifications can now be prefixed with `-` to indicate
    negation
  - transitive_source_jars is now exposed on JavaInfo.
  - Add six to deps of has_services=1 py_proto_librarys.
  - java_tests no complain when use_testrunner is explicitly set to 1
    and main_class is set.
  - transitive_source_jars is now exposed on JavaInfo.
  - Debug messages generated by `print()` are not being filtered out
    by --output_filter anymore, it's recommended not to use them in
    production code.
  - in the Label() function, relative_to_caller_repository is now
    deprecated.
  - java_tests no complain when use_testrunner is explicitly set to 1
    and main_class is set.
  - Bazel's default hash function was changed from MD5 to SHA256.
    In particular, this affects users of remote caching and
    execution, as
    all hashes will be SHA256 by default.
  - Remove redirects for domains be.bazel.build and cr.bazel.build
    from the source for docs.bazel.build (because those subdomains
    don't resolve here; they resolve to bazel.build, which has the
    redirects for them)
  - First argument of 'load' must be a label. Path syntax is removed.
      (label should start with '//' or ':').
  - Document startup option --host_javabase
  - The --host_platform and --platform flags are no longer
    experimental.
