Incompatible changes:

  - Added --incompatible_py3_is_default to test switching the default
    Python version to PY3 for py_binary/py_test targets that do not
    specify a version. See #7359.
  - //tools/cmd_line_differ has been renamed to //tools/aquery_differ
    & can now compare (in addition to command lines) inputs of
    actions given 2 aquery results.
  - java_(mutable_|)proto_library: removed strict_deps attribute.
  - The flag --incompatible_list_based_execution_strategy_selection
    was added and is used to ease the migration to the new style of
    specifying
    execution strategy selection and fallback behavior. The
    documentation for
    this flag is here: https://github.com/bazelbuild/bazel/issues/7480
  - Added --incompatible_py2_outputs_are_suffixed, for switching the
    bazel-bin symlink to point to Python 3 outputs instead of Python
    2 outputs. See
    [#7593](https://github.com/bazelbuild/bazel/issues/7593).

New features:

  - Make actions.args() object chainable.
  - Added --incompatible_windows_style_arg_escaping flag: enables
    correct subprocess argument escaping on Windows. (No-op on other
    platforms.)
  - Added --incompatible_windows_escape_jvm_flags flag: enables
    correct java_binary.jvm_flags and java_test.jvm_flags
    tokenization and escaping on Windows. (No-op on other platforms.)

Important changes:

  - Allow running aquery against the current state of Skyframe
  - Added support for the "navigation" resource directory to Android
    resource processing in Bazel. This is used by the Navigation
    Architecture Component.
  - --incompatible_disable_runtimes_filegroups was flipped
    (https://github.com/bazelbuild/bazel/issues/6942)
  - Incompatible flag `--incompatible_linkopts_in_user_link_flags`
    has been flipped (https://github.com/bazelbuild/bazel/issues/6826)
  - Incompatible flag `--incompatible_dont_emit_static_libgcc` has
    been flipped (https://github.com/bazelbuild/bazel/issues/6825)
  - --incompatible_disallow_filetype is enabled by default.
  - Fixed issue where exceptions and stacktraces were silently
    swallowed in the Android resource processing pipeline.
  - `--incompatible_disable_expand_if_all_available_in_flag_set` has
    been flipped (https://github.com/bazelbuild/bazel/issues/7008)
  - --incompatible_disallow_dict_plus is enabled by default
  - Adds --incompatible_disable_objc_library_resources to disable
    resource attributes in objc_library. Please migrate these
    attributes to `data` instead.
  - --incompatible_disallow_old_style_args_add is enabled by default.
  - Using the `native` module in BUILD files is deprecated. It will
    be forbidden with --incompatible_disallow_native_in_build_file.
  - (Python rules) PyRuntimeInfo is exposed to Starlark, making it
    possible for Starlark rules to depend on or imitate `py_runtime`.
    The `files` attribute of `py_runtime` is no longer mandatory.
  - incompatible_use_toolchain_providers_in_java_common: pass
    JavaToolchainInfo and JavaRuntimeInfo providers to java_common
    APIs instead of configured
    targetshttps://github.com/bazelbuild/bazel/issues/7186.
  - is_using_fission crosstool variable is now exposed in all compile
    actions when fission is active (it used to be exposed only for
    linking actions).
  - incompatible_use_toolchain_providers_in_java_common: pass
    JavaToolchainInfo and JavaRuntimeInfo providers to java_common
    APIs instead of configured
    targetshttps://github.com/bazelbuild/bazel/issues/7186.
  - `py_runtime` gains a `python_version` attribute for specifying
    whether it represents a Python 2 or 3 interpreter.
  - `--incompatible_java_coverage` is enabled by default.
  - Starlark rules can safely declare attributes named "licenses"
  - When using
    --incompatible_list_based_execution_strategy_selection, Bazel
    will use remote execution by default (if you specify
    --remote_executor), otherwise persistent workers (if the action
    supports it), otherwise sandboxed local execution (if the action
    and platform supports it) and at last unsandboxed local
    execution. The flags --spawn_strategy and --strategy continue to
    work as before - this only sets new defaults for the case where
    you don't specify these flags.
  - Set default value of --incompatible_remap_main_repo to true.
  - Set default value of --incompatible_remap_main_repo to true.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
