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

    `java_import` rule.
  - blaze query: use --proto:output_rule_attrs to filter for given
    attributes
  - Added Android NDK r15 support, including compatibility with
    Unified Headers.

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

    load("@bazel_tools//tools/build_defs/repo:http.bzl",
    "http_archive")
      instead.
  - flaky_test_attempts supports the regex@attempts syntax, like
    runs_per_test.
  - Fixed include paths for NDK r13+ llvm-libc++ headers to
    `ndk/sources/cxx-stl/llvm-libc++/include` and
    `ndk/sources/cxx-stl/llvm-libc++abi/include`

      instead.
  - Removed flag `--incompatible_load_argument_is_label`.
  - CcToolchain: Introduced action_config for
    "c++-link-transitive-dynamic-library"
  - Use bazel dump --action_graph=/path/to/action.proto
    --action_graph:targets://foo:bar,//foo:foo to filter for certain
    targets in the action graph dump.
  - Added Android NDK r16 support. Use --cxxopt='-std=c++11` compile
    with the C++11 standard, and
    `--android_crosstool_top=@androidndk//:toolchain-libcpp` to use
    the `libc++` STL.

     Change git clone to pull all history, so all needed commits can
     be accessed.

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.
  - android_* rules no longer support legacy_native_support attribute.

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
    long been enabled by default
  - New version of aapt2 and Resources.proto.
  - Make PIC and non PIC outputs for C++ compilation with Tree
    Artifacts

   + 03964c8:
     [java_common.compile] Name output source jar relative to the
     output jar name

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.

Incompatible changes:

  - ctx.fragments.apple.{xcode_version,ios_minimum_os} is not
    supported anymore. The same information is accessible through the
    target @bazel_tools//tools/osx:current_xcode_config: point an
    implicit attribute to it (i.e.
    attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co
    nfig")) then use
    ctx.attr._xcode_config[apple_common].XcodeVersionConfig].
  - ctx.fragments.apple.minimum_os_for_platform_type is not supported
    anymore. The same information is accessible through the target
    @bazel_tools//tools/osx:current_xcode_config: point an implicit
    attribute to it (i.e.
    attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co
    nfig")) then use
    ctx.attr._xcode_config[apple_common].XcodeVersionConfig].minimum_o
    s_for_platform_type .
  - ctx.fragments.apple.sdk_version_for_platform is not supported
    anymore. The same information is accessible through the target
    @bazel_tools//tools/osx:current_xcode_config: point an implicit
    attribute to it (i.e.
    attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co
    nfig")) then use
    ctx.attr._xcode_config[apple_common].XcodeVersionConfig].sdk_versi
    on_for_platform .
  - --javabase=<absolute path> and --host_javabase=<absolute path>
    are not supported anymore. If you need this functionality
    java_runtime_suite(name="suite", default=":runtime")
    java_runtime(name="runtime", java_home=<path to the JDK>) is an
    alternative.
  - The flag --incompatible_descriptive_string_representations is no
    longer available, old style string representations of objects are
    not supported
    anymore.
  - The flag --incompatible_disallow_set_constructor is no longer
    available, the deprecated `set` constructor is not available
    anymore.
  - += on lists now mutates them. `list1 += list2` is now equivalent
    to `list1.extend(list2)` and not equivalent to `list1 = list1 +
    list2` anymore.
  - the target_apple_env and apple_host_system_env methods on
    ctx.fragments.apple are not supported anymore. The same
    information is accessible through apple_common.target_apple_env
    and apple_common.apple_host_system_env . They need the Xcode
    configuration as an argument, which can be obtained by declaring
    an implicit dependency on it (i.e.
    attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co
    nfig")) and then calling e.g.
    apple_common.apple_host_system_env(ctx.attr._xcode_config[apple_co
    mmon.XcodeVersionConfig]).
  - C++ toolchain identifiers are not in the name of the output
    directory anymore.
  - Selecting on "xcode_version" and
    "{ios,tvos,macos,watchos}_sdk_version" is not supported anymore.
    What was config_setting(values={"$FOO_version": $VALUE}) is now
    config_setting(flag_values={"@bazel_tools//tools/osx:$FOO_version_
    flag": $VALUE}).
  - Selecting on "xcode_version" and
    "{ios,tvos,macos,watchos}_sdk_version" is not supported anymore.

New features:

  - runfiles, sh: Shell scripts may now depend on
    //src/tools/runfiles:runfiles_sh_lib and source runfiles.sh. The
    script defines the `rlocation` function which returns runfile
    paths on every platform.
  - In addition to $(location), Bazel now also supports $(rootpath)
    to obtain
        the root-relative path (i.e., for runfiles locations), and
    $(execpath) to
        obtain the exec path (i.e., for build-time locations)

Important changes:

  - android_binary now supports custom debug keys via the debug_key
    attribute.
  - Updated Android proguard to 5.3.3. It now works with android-24+.
  - --experimental_use_parallel_android_resource_processing and
    --experimental_android_use_nocompress_extensions_on_apk are
    removed. These features are fully rolled out.
  - Fixes bazelbuild#2574
  - Fixes bazelbuild#3834
  - Enable experimental UI by default.
  - .
    RELNOTES: None.
    RELNOTES: No.
  - Add memory profiler.
  - [Bazel] {java,cc}_proto_library now look for dependencies in
    @com_google_protobuf, instead of in @com_google_protobuf_$LANG
  - Improved merge.sh script in cookbook.
  - Fixing regression to --experimental_remote_spawn_cache
  - Support for linker scripts in NativeDepsHelper (e.g.,
    android_binary)
  - Skylark semantics flags now affect WORKSPACE files and repository
    rules.
  - ctx.outputs.executable is deprecated. Use DefaultInfo(executable
    = ...) instead.
  - Update "mirror.bazel.build" urls to use https.
  - Improve --config logging when --announce_rc is present.
  - Document interaction between test_suite and target exclusions
  - Replace version numbers for Bazel installers with "<version>"
    (because this will change often)
  - Published command lines should have improved lists of effective
    options.
  - --incremental_dexing_binary_types has been removed. All builds
    are supported by incremental dexing (modulo proguard and some
    blacklisted dx flags).
  - Document --host_javabase, --host_java_toolchain

Release 0.7.0 (2017-10-18)

Baseline: 5cc6246

Cherry picks:
   + e79a110:
     Windows,bootstrapping: fix build_windows_jni.sh

Incompatible changes:

  - The --output=location flag to 'bazel query' cannot be used with
    query expressions that involve the 'buildfiles' or 'loadfiles'
    operators. This also applies to 'genquery' rules.
  - Operators for equality, comparison, 'in' and 'not in' are no
    longer associative,
      e.g.  x < y < z  is now a syntax error. Before, it was parsed
    as:  (x < y) < z.
  - In strings, octal sequences greater than \377 are now forbidden
    (e.g. "\\600").
      Previously, Blaze had the same behavior as Python 2, where
    "\\450" == "\050".
  - Using tabulation for identation is now fobidden in .bzl files
  - `load` is now a language keyword, it cannot be used as an
    identifier
  - lvalues must have define at least one variable (i.e. we forbid
    `[] = f()`).
  - Fixed a bug whereby multiple load() statements could appear on
    the same line
  - -extra_checks:off is no longer supported; use
    -XepDisableAllChecks instead
  - java_common.java_toolchain_attr is removed. Depend on the
    java_toolchain_alias() rule to accomplish the same thing.
  - cc_common.cc_toolchain_attr and java_common.java_runtime_attr are
    not supported anymore and were replaced with the
    cc_toolchain_alias() and java_runtime_alias() rules.
  - Noop flag --deprecated_generate_xcode_project deleted.
  - Objects in Skylark are converted to strings in a more descriptive
    and less harmful way (they don't leak information that shouldn't
    be accessed by Skylark code, e.g. nondeterministic memory addresses
    of objects).
  - `set` is deprecated in BUILD and .bzl files, please use `depset`
    instead. Ordering names have also been changed, please use "default",
    "postorder", "preorder", and "topological" instead of "stable",
    "compile", "naive_link", and "link" correspondingly.
  - Integer overflow (on signed 32 bit numbers) in BUILD/bzl files is
    an error.
  - Keyword-only syntax in a function definition is now forbidden
      e.g. `def foo(a, *, b)` or `def foo(a, *b, c)`
  - --incompatible_comprehension_variables_do_not_leak defaults to
    "true."
      Iteration variable becomes inaccessible after a list/dict
    comprehension.
  - @bazel_tools//tools/build_defs/docker:docker.bzl is no longer
    available, please see https://github.com/bazelbuild/rules_docker.

New features:

  - Zipped LLVM profiles are now supported.
  - LIPO maps to ThinLTO for LLVM builds.
  - Change to handle LLVM FDO zipped profile contents correctly.
  - Do not disable fully dynamic linking with ThinLTO when invoked
    via LIPO options.
  - There is now a 'siblings' query function. See the query
    documentation for more details.
  - Added the print_action command, which outputs the
    actions needed to build a given target in the form of an
    ExtraActionSummary proto in text format.
  - android_binary now supports proguard_apply_dictionary to specify
    a custom dictionary to use for choosing names to obfuscate
    classes and members to.

Important changes:

  - Windows: bazel clean --expunge works
  - First argument of 'load' should be a label. Path syntax is
    deprecated (label should start with '//' or ':').
  - Octal prefix '0' is deprecated in favor of '0o' (use 0o777
    instead of 0777).
  - The extension_safe attribute of apple_binary no longer validates
    transitive dependencies are compiled against extension_safe APIs.
  - Parentheses around the tuple are now mandatory in [a for b in c
    if 1, 2]
  - Adjust the thresholds for --test_verbose_timeout_warnings so that
    it can recommending timeout increases and won't recommend
    timeouts that are too close to the actual timeout.
  - Iterating on a `depset` object is deprecated. If you need an
    iterable, call the `.to_list()` method first.
  - Bazel now uses tools from action_configs in Crosstool by default
    (as oposed to using top level tools).
  - Incremental dexing errors on combination of --multidex=off and
    either --main-dex-list or --minimal-main-dex.
  - When using the dictionary literal syntax, it is now an error to
    have duplicated keys (e.g.  {'ab': 3, 'ab': 5}).
  - New property on android_sdk: aapt2
      Choose the version of aapt on android_binary
  - Add idl_preprocessed attribute to android_library, so that
    preprocessed aidl files can be passed to android_library for
    compiling
  - Bazel's remote_worker backend for remote execution supports
    sandboxing on Linux now. Check
    https://github.com/bazelbuild/bazel/blob/master/src/tools/remote_w
    orker/README.md for details.
  - Allows flags that expand to take values.
  - Make querying attributes formed by selector lists of list types
    more efficient by no longer listing every possible combination of
    attribute value but by more compactly storing the possible values
    of the list.
  - writing build events to a file is no longer experimental
  - set --rewrite_calls_to_long_compare to false by default.
  - ObjC and C++ coverage feature is unified under name 'coverage'
  - Enable --incremental_dexing for Android builds by default. Note
    that some dexopts are incompatible with incremental dexing,
    including --force-jumbo.
  - Evaluation will soon use checked arithmetics and throw an error
    instead of overflow/underflow.
  - Implicit iteration in the CROSSTOOL has been removed, use
    explicit 'iterate_over' message.
  - Add option for Android specific grte_top
  - Crosstool patches are only applied if the toolchain doesn't define
    'no_legacy_features' feature.
  - 'platform_type' is now a mandatory attribute on apple_binary and
    apple_static_library rules.
    If this change breaks your build, feel free to add platform_type
    = 'ios' to any apple_binary and apple_static_library
    targets in your project, as this was the previous default
    behavior.
  - Remove apple_watch2_extension build rule. Users should be using
    the skylark watchos_application and watchos_extension rules.
    https://github.com/bazelbuild/rules_apple has details.
  - Check stderr to detect if connected to a terminal.  Deprecate
    --isatty.
  - Commands that shut down the server (like "shutdown") now ensure
    that the server process has terminated before the client process
    terminates.
  - Remove apple_watch1_extension and apple_watch_extension_binary
    rules. Users should be using the skylark watchos_application and
    watchos_extension rules.
    https://github.com/bazelbuild/rules_apple has details.
  - Windows: Wrapper-less CROSSTOOL becomes default now.
    set USE_MSVC_WRAPPER=1 if you still want to use wrapper script.
  - Ignore --glibc in the Android transition.
  - Remove --experimental_android_use_singlejar_for_multidex.
  - nocopts now also filter copts
  - 'strip' action is now configured via feature configuration
  - The Build Event Service (BES) client now properly supports
    Google Applicaton Default Credentials.
  - Flags from action_config get added first to the command line
    first, before the flags from features.
  - update dexing tools to Android SDK 26.0.1
  - Bazel Android support now requires build-tools 26.0.1 or later.
  - `bazel info output_path` no longer relies on the root directory
    filename being equal to the workspace name.
  - The `print` function now prints debug messages instead of
    warnings.
  - speedup of incremental dexing tools
  - --announce_rc now controls whether bazelrc startup options are
    printed to stderr.
  - Removing a few unused objc_provider keys.
  - Improved logging when workers have to be restarted due to its
    files having changed.
  - Top-level `if` statements are now forbidden.
  - Java protos are compiled to Java 7 bytecode.
  - All Android builds now use the desugar tool to support some Java
    8 features by default. To disable, use the --nodesugar_for_android flag.
  - Skylark-related options may now appear as "common" command
    options in the .bazelrc
  - Python is now required to build bazel.
  - New --build_runfile_manifests flag controls production of
    runfiles manifests.
  - Enable debug info for Java builds
  - Allow java_lite_proto_library in the deps of android rules.
  - .so files in APKs will be memory-page aligned when
    android_binary.nocompress_extensions contains ".so" and
    --experimental_android_use_nocompress_extensions_on_apk is
    specified.
  - Skylark providers can specify allowed fields and their
    documentation.
  - Support ctx.actions.args() for more efficient Skylark command
    line construction.
  - The remote HTTP/1.1 caching client (--remote_rest_cache) now
    distinquishes between action cache and CAS. The request URL for
    the action cache is prefixed with 'ac' and the URL for the CAS
    is prefixed with 'cas'.
  - `JavaInfo` is a preferred alias to `java_common.provider`.
  - J2ObjC version updated to 2.0.3.
  - A new Java coverage implementation is available. Makes possible
    coverage for Skylark JVM rules.
  - Make proguard_apply_dictionary also apply to class and package
    obfuscation, not just class members.
  - android_binary.nocompress_extensions now applies to all files in
    the APK, not just resources and assets.
  - The apple_genrule rule that is distributed with Bazel has been
    deleted. Users who wish to use genrules with Xcode's
    DEVELOPER_DIR set should use the rules in
    https://github.com/bazelbuild/rules_apple instead.
  - The swift_library rule that is distributed with Bazel has been
    deleted. Users who wish to compile Swift should use the rules in
    https://github.com/bazelbuild/rules_apple instead.
  - The Build Event Protocol's File.uri field is now properly
    encoded according to RFC2396.
  - Deprecated: Using the android_library.deps attribute to
    implicitly export targets to dependent rules. If your code is
    using this feature, Bazel will raise a warning. To fix, please
    use android_library.exports to explicitly specify exported
    targets. Run with
    --experimental_allow_android_library_deps_without_srcs=false to
    ensure forward compatibility when this feature is removed in a
    future release.
  - java_common.create_provider is now supported with creating ijars
    by default. This introduces incompatibilities for existing users.
    Please set use_ijar=False if you don't want to use ijars.
  - Tests can now write files to TEST_UNDECLARED_OUTPUTS_DIR and
    TEST_UNDECLARED_OUTPUTS_ANNOTATIONS_DIR and these will be
    reflected under bazel-testlogs.
  - remove unused --host_incremental_dexing flag
  - Stop using --undefined dynamic_lookup in Apple links. Enables
    unresolved symbol errors.
  - All test output files included for cached, uncached, and multiple
    attempt tests.
  - Android rules no longer restrict the manifest file to be named
    "AndroidManifest.xml".
  - Boolean flag values will now get normalized to 1 or 0 in
    canonicalize-flags output.
  - added experimental --use_new_category_enum to the help command to
    output options grouped by the new type of category.
  - Expose output jars and jdeps in java_common.provider, when
    available.
  - android_library targets are no longer allowed to use deps to
    export targets implicitly; please use android_library.exports
    instead.
  - New depset API
  - apple_binary and apple_static_library no longer support
    compilation attributes such as 'srcs'. If this breaks any
    existing targets, you may migrate all such attributes to a new
    objc_library target and depend on that objc_library target via
    the 'deps' attribute of apple_binary or apple_static_library.
