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

  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

• --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.

  rules.
• Use --expand_configs_in_place as a startup argument to change the

  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= and --host_javabase=
  are not supported anymore. If you need this functionality
  java_runtime_suite(name="suite", default=":runtime")
  java_runtime(name="runtime", java_home=) 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}).

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_android_use_nocompress_extensions_on_apk are
  removed. These features are fully rolled out.
• Fixes #2574
• Fixes #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 ""
  (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

0.7.0

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 ...
