Incompatible changes:

  - (Starlark rules) The legacy "py" provider can no longer be passed
    to or produced by native Python rules; use
    [PyInfo](https://docs.bazel.build/versions/master/skylark/lib/PyIn
    fo.html) instead. See
    [#7298](https://github.com/bazelbuild/bazel/issues/7298) for more
    information.
  - (Python rules) The `default_python_version` attribute of the
    `py_binary` and `py_test` rules has been renamed to
    `python_version`. Also, the `--force_python` flag has been
    renamed to `--python_version`. See
    [#7308](https://github.com/bazelbuild/bazel/issues/7308) for more
    information.
  - (Python rules) The python version now changes to whatever version
    is specified in a `py_binary` or `py_test`'s `python_version`
    attribute, instead of being forced to the value set by a command
    line flag. You can temporarily revert this change with
    `--incompatible_allow_python_version_transitions=false`. See
    [#7307](https://github.com/bazelbuild/bazel/issues/7307) for more
    information.
  - --incompatible_disable_third_party_license_checking` is enabled
    by default
  - Introduced --incompatible_use_python_toolchains, which supersedes
    --python_top/--python_path. See #7899 and #7375 for more
    information.
  - Python 3 is now the default Python version (for `py_binary` and
    `py_test` targets that don't specify the `python_version`
    attribute). Targets that are built for Python 3 will no longer
    have their output put in a separate `-py3` directory; instead
    there is now a separate `-py2` directory for Python 2 targets.
    See #7359 and #7593 for more information.
  - objc_library resource attributes are now disabled by default.
    Please migrate them to data instead. See
    https://github.com/bazelbuild/bazel/issues/7594 for more info.
  - Flip --incompatible_windows_escape_jvm_flags to true. See
    https://github.com/bazelbuild/bazel/issues/7486

New features:

  - genrules now support a $(RULEDIR) variable that resolves to the
    directory where the outputs of the rule are put.
  - Added --incompatible_windows_native_test_wrapper flag: enables
    using the Bash-less test wrapper on Windows. (No-op on other
    platforms.)

Important changes:

  - incompatible_use_jdk11_as_host_javabase: makes JDK 11 the default
    --host_javabase for remote jdk
    (https://github.com/bazelbuild/bazel/issues/7219)
  - Makes genquery somepath output deterministic.
  - Tristate attributes of native rules now reject True/False (use
    1/0)
  - Rollback of "Tristate attributes of native rules now reject
    True/False (use 1/0)"
  - Tristate attributes of native rules now reject True/False (use
    1/0)
  - Added -incompatible_do_not_split_linking_cmdline flag. See #7670
  - Tristate attributes of native rules now temporarily accept
    True/False again
  - `--incompatible_disable_legacy_crosstool_fields` has been flipped
    (https://github.com/bazelbuild/bazel/issues/6861)
    `--incompatible_disable_expand_if_all_available_in_flag_set` has
    been flipped (https://github.com/bazelbuild/bazel/issues/7008)
  - `--incompatible_disable_legacy_crosstool_fields` has been flipped
    (https://github.com/bazelbuild/bazel/issues/6861)
    `--incompatible_disable_expand_if_all_available_in_flag_set...
    RELNOTES: None.
  - --incompatible_no_transitive_loads is enabled by default.
  - Makes TreeArtifact deterministic.
  - --incompatible_no_transitive_loads is enabled by default.
  - Android NDK C++ toolchain is now configured in Starlark. This
    should be a backwards compatible change, but in case of bugs
    blame unknown commit.
  - `--incompatible_disable_legacy_crosstool_fields` has been flipped
    (https://github.com/bazelbuild/bazel/issues/6861)
    `--incompatible_disable_expand_if_all_available_in_flag_set` has
    been flipped (https://github.com/bazelbuild/bazel/issues/7008)
  - --incompatible_no_transitive_loads is enabled by default.
  - --incompatible_bzl_disallow_load_after_statement is enabled
  - Added `--incompatible_require_ctx_in_configure_features`, see
    https://github.com/bazelbuild/bazel/issues/7793 for details.
  - Flag --incompatible_merge_genfiles_directory is flipped. This
    removes the directory `bazel-genfiles` in favor of `bazel-bin`.
  - previously deprecated flag --experimental_remote_spawn_cache was
    removed
  - `--incompatible_disallow_load_labels_to_cross_package_boundaries`
    is enabled by default
  - Fix an issue where the Android resource processor did not surface
    errors from aapt2 compile and link actions.
  - --incompatible_no_attr_license is enabled by default
  - `--incompatible_disable_crosstool_file` has been flipped
    (https://github.com/bazelbuild/bazel/issues/7320)
  - A new flag `--incompatible_string_join_requires_strings` is
    introduced. The sequence argument of `string.join` must contain
    only string elements.
  - --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile
    s_tree has been flipped
  - Incompatible flag `--incompatible_disable_legacy_cc_provider` has
    been flipped (see https://github.com/bazelbuild/bazel/issues/7036
    for details).
  - Don't drop the analysis cache when the same --define flag is set
    multiple times and the last value is the same (e.g. if the
    current invocation was run with "--define foo=bar" and the
    previous one was run with "--define foo=baz --define foo=bar").
  - The --incompatible_disable_genrule_cc_toolchain_dependency flag
    has been flipped (see
    https://github.com/bazelbuild/bazel/issues/6867 for details).
  - Incompatible change
    `--incompatible_remove_cpu_and_compiler_attributes_from_cc_toolcha
    in` has been flipped (see
    https://github.com/bazelbuild/bazel/issues/7075 for details).
  - --noexperimental_java_coverage is a no-op flag.
  - --experimental_java_coverage/--incompatible_java_coverage flag was
    removed. See #7425.
  - incompatible_use_toolchain_providers_in_java_common: pass
    JavaToolchainInfo and JavaRuntimeInfo providers to java_common
    APIs instead of configured targets
    (https://github.com/bazelbuild/bazel/issues/7186.)
  - --incompatible_remote_symlinks has been flipped. The remote
    caching and execution protocol will now represent symlinks in
    outputs as such. See
    https://github.com/bazelbuild/bazel/issues/7917 for more details.
  - Bazel is now ~20MiB smaller, from unbundling the Android rules'
    runtime dependencies.

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.
