bazel (0.9.0) unstable; urgency=low

  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.
