Incompatible changes:

  - The order of dict-valued attributes is now the order in the BUILD
    file (or in the Skylark dict they were created from) and not
    lexicographically sorted.

New features:

  - The new "--direct_run" flag on "blaze run" lets one run
    interactive binaries.
  - "blaze run --direct_run" with tests now gives the test an
    approximation of the official test environment.
  - "blaze run --direct_run" now exports the
    BUILD_{WORKSPACE,WORKING}_DIRECTORY variables to tell the binary
    about the cwd of the client and the workspace root.
  - New Android device test rule: android_instrumentation_test.
  - Add option to dump the action graph to a file: 'bazel dump
    --action_graph=/path/to/file'.
  - Pass `tags` from `java_import_external` rule to the generated
    `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.
  - Adds --ltobackendopt and --per_file_ltobackendopt for passing
    options to ThinLTO LTO backend compile actions only.

Important changes:

  - Fix how libraries to link is specified to archiver actions.
  - Fix how libraries_to_link are expanded in the archiver command
    line.
  - stop using --no-locals in android coverage builds
  - apple_binary can now generate dSYM outputs with the
    --apple_generate_dsym=true flag.
  - Fix FDO_STAMP_MACRO to only be set when fdoBuildStamp is not null.
  - Improved clarity of warning message for unsupported NDK revisions.
  - Add lint check for discouraging glob(["**/*.java"])
  - unifly lint glob(["**/*.java"]) message
  - Removed flags `--incompatible_checked_arithmetic`,
    `--incompatible_dict_literal_has_no_duplicates`,
    `--incompatible_disallow_keyword_only_args`, and `
    --incompatible_comprehension_variables_do_not_leak`.
  - Add "proto_source_root" flag to proto_library.
  - Updated default android_cpu value to armeabi-v7a
  - In skylark, print(target) now shows the provider keys of a
    target, as debug information.
  - The native http_archive rule is deprecated. Use the
      Skylark version available via
    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`
  - --config flags now expand in place by default.
  - aar_import now sets java.transitive_exports.
  - repository_cache is no longer experimental and enabled by default.
  - BAZEL_LINKOPTS is now consulted when autoconfiguring c++ toolchain
  - The native git_repository rule is deprecated. Use the
      Skylark version available via
    load("@bazel_tools//tools/build_defs/repo:git.bzl",
    "git_repository")
      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.
  - Add a --build_event_publish_all_actions flag to allow all actions
    to be published via the BEP.
  - C++: Introduced --experimental_drop_fully_static_linking_mode
  - Removed cc_inc_library, please use cc_library instead
  - CppRules: cc_binary/cc_test now enable 'static_linking_mode' or
    'dynamic_linking_mode'.

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.
