Release 0.4.0 (2016-10-26)

Baseline: 088bbc6

Cherry picks:
   + b01160c: Stamp Windows release.
   + 2d6736e: Add --no-tty for gpg signing
   + 9b1dfb8: Remove .sig file before gpg signing
   + 81aede1: Reimplement whole archive on Windows

Incompatible changes:

  - Skylark: updating list/dicts while they are being looped over is not
    allowed. Use an explicit copy if needed ("for x in list(mylist):").
  - Bazel now uses the --cpu flag to look up Jvms; it falls back
    to "default" if it can't find a Jvm matching the CPU value.
  - --command_port=-1 to use AF_UNIX for client/server communications
    is not supported anymore.
  - Sandboxed actions can access the network by default, unless their
    target has a "block-network" tag.

New features:

  - Files now have an "extension" property in Skylark.

Important changes:

  - Added a new flag --sandbox_tmpfs_path, which asks the sandbox to
    mount an empty, writable directory at a specified path when
    running actions. (Supported on Linux only for now.)
  - Update protoc-3.0.0-mingw.exe to a working (statically linked)
    binary
  - apple_static_library rule to create multi-architecture static
    archive files from Objc/C++/Swift dependencies on apple platforms
  - JS: Add support for localization with closure managed rules.
  - Create a flag --android_dynamic_mode to turn off dynamic mode
    during the Android split transition.
  - Darwin sandboxing is default.
  - Remove flag --experimental_zip_tree_artifact from j2objc Java
    annotation processing support.
  - A few functions are added to BUILD files for consistency (hash,
    dir,
      hasattr, getattr) with .bzl files, although they are not very
    useful.
  - --watchfs is now a command option; the startup option of the same
        name is deprecated. I.e., use bazel build --watchfs, not
    blaze --watchfs
        build.

Release 0.3.2 (2016-10-07)

Baseline: 023a7bd

Cherry picks:
   + bebbbe5: Fix dependency on libtool's helper script
              make_hashed_objlist.py.
   + 8a0d45f: Add the version information to the bazel.exe file
   + 2bc0939: Allow new_ rules to overwrited BUILD files in
              downloaded repos
   + c5545fd: Rollback of commit
              96d4628.
   + eb87208: Make cc_configure on Windows more robust
   + c30432c: Fix cc_configure on Windows
   + 95b16a8: sandbox: Replace the error-prone lazy cleanup of
              sandbox directories by a simple synchronous cleanup.
   + e898023: Fix bazelbuild#1849: Sandboxing on OS X should be turned off by
              default for 0.3.2.
   + ffdc05d: Add action_config and feature for linking on Windows

Incompatible changes:

  - If you maintain a rule that uses persistent workers, you'll have
    to specify execution_requirements={"supports-workers": 1} in the
    ctx.action that intends to run a tool with workers. The
    WorkerSpawnStrategy will alert you with a warning message if you
    forget to make this change and fallback to non-worker based
    execution.
  - It is now an error to include a precompiled library (.a, .lo, .so)
    in a cc_library which would generate a library with the same name
    (e.g., libfoo.so in cc_library foo) if that library also contains
    other linkable
    sources.
  - The main repository's execution root is under the main
    repository's workspace name, not the source directory's basename.
    This shouldn't
    have any effect on most builds, but it's possible it could break
    someone doing
    weird things with paths in actions.
  - Blaze doesn't support Unix domain sockets for communication
    between its client and server anymore. Therefore, the
    --command_port command line argument doesn't accept -1 as a valid
    value anymore.
  - Skylark: It is an error to shadow a global variable with a local
    variable after the global has already been accessed in the
    function.
  - bin_dir and genfiles_dir are now properties of ctx, not
    configuration. That is, to access the bin or genfiles directory
    from a
    Skylark rule, use ctx.bin_dir or ctx.genfiles_dir (not
    ctx.configuration.{bin,genfiles}_dir).  At the moment, you can
    access
    {bin,genfiles}_dir from either, but the ctx.configuration version
    will
    stop working in a future release.
  - filegroup-based C++ toolchains are not supported anymore.
    --*_crosstool_top options must always point to a
    cc_toolchain_suite rule (or an alias of one).
  - repository_ctx.{download,download_and_extract,execute} API now use
                   named parameters for optional parameters and no
    longer uses argument
                   type to distinguished between arguments
    (executable attribute name
                   must be specified when preceding optional
    arguments are missing).

New features:

  - print and fail are now available in BUILD files.

Important changes:

  - Added @bazel_tools//tools/build_defs/repo/git.bzl as a Skylark
    rule for Git repositories.
  - Added @bazel_tools//tools/build_defs/repo/maven_rules.bzl as a
    Skylark rule for Maven repositories.
  - Add global hash() function for strings (only)
  - Improve Android split transition handling.
  - Removes exports_manifest attribute from android_binary rule.
  - java_proto_library: control strict-deps through a rule-level and
    a package-level attribute.
  - Persistent workers are now used by default for Java compilation
    in Bazel, which should speed up your Java builds by ~4x. You can
    switch back to the old behavior via --strategy=Javac=standalone.
    Check out http://www.bazel.io/blog/2015/12/10/java-workers.html
    for more details.
  - objc_* rules can now depend on any target that returns an "objc"
    provider.
  - Adds support for NDK12 to `android_ndk_repository` rule in Bazel.
  - Test targets can disable the JUnit4 test security manager via a
    property.
  - Disable the Android split transition if --android_cpu and
    fat_apk_cpu are both empty.
  - New sandboxing implementation for Linux in which all actions run
    in a separate execroot that contains input files as symlinks back
    to the originals in the workspace. The running action now has
    read-write access to its execroot and /tmp only and can no longer
    write in arbitrary other places in the file system.
  - Add worker support to single jar.
  - Invoke source jar action as a worker.
  - Sandboxed builds allow network access for builds by default.
    Tests will still be run without networking, unless
    "requires-network" is specified as a tag.
  - Add path.realpath() method for Skylark repositories.
  - On Mac devices, detect locally installed versions of xcode to:
     1. Use a sensible default if xcode is required but
    --xcode_version is unspecified.
     2. Use sensible default iOS SDK version for the targeted version
    of xcode if ios_sdk_version is unspecified.
  - Emacs' [C-x `], a.k.a. next-error, works again in emacsen >= 25.1
  - swift_library can be used to build watchOS apps.
  - Exposes the is_device field on Apple platform objects and adds
    the apple_common.platform_type(name) method to retrieve a
    platform_type value that can be passed to methods like the Apple
    fragment's multi_arch_platform.
  - Move Skylark git_repository rules to git.bzl
  - Add support for aspects to attr.label() attributes
  - Global varaiables HOST_CFG and DATA_CFG are deprecated in favor
    of strings "host"
    and "data.
    Argument `cfg = "host"` or `cfg = "data"` is mandatory if
    `executable = True` is provided for a label.
  - The deprecation attribute of all rules now causes warnings
    to be printed when other targets depend on a target with that
    attribute set.
  - Change default of --[no]instrument_test_targets to false, change
    default --instrumentation_filter (which previously tried to
    exclude test targets by heuristic) to only exclude targets in
    javatests.
  - Remove deprecated absolute paths in blaze IDE artifacts
  - When using android_binary.manifest_merger="android" the merger
    produces a summary log next to the merged manifest artifact.
  - Allow different default mallocs per configuration.

Release 0.3.1 (2016-07-29)

Baseline: 792a9d6

Cherry picks:
   + 25e5995: Rollback of commit
              a277033.
   + 2479405: Fix NPE with unset maven_jar sha1
   + 3cf2126: Rewrite the extra action info files if the data within
              them changes.
   + 5a9c6b4: JavaBuilder: Reintroduce the -extra_checks flag.

Incompatible changes:

  - Removed predefined Python variable "generic_cpu".
  - Skylark rules: if you set "outputs" or an attribute to a
    function, this function must now list its required attributes as
    parameters (instead of an attribute map).
  - The host_platform and target_platform entries are not written to
    the master log anymore.
  - Bazel requires Hazelcast 3.6 or higher now for remote execution
    support, because we upgraded our client library and the protocol
    it uses is incompatible with older versions.

New features:

  - LIPO context (--lipo_context) can now also be a cc_test (in
    addition to cc_binary)

Important changes:

  - If --android_crosstool_top is set, native code compiled for
    android will always use --android_compiler and not --compiler in
    choosing the crosstool toolchain, and will use --android_cpu if
    --fat_apk_cpu is not set.
  - Add --instrument_test_targets option.
  - apple_binary supports a new platform_type attribute, which, if
    set to "watchos", will build dependencies for Apple's watchOS2.
  - objc_binary now supports late-loaded dynamic frameworks.
  - Native Swift rules no longer pull in module maps unconditionally.
    Use --experimental_objc_enable_module_maps for that.
  - Merged manifests are guaranteed to have the application element
    as the last child of the manifest element as required by Android
    N.
  - The Android manifest merger is now available as an option for
    android_binary rules. The merger will honor tools annotations in
    AndroidManifest.xml and will perform placeholder substitutions
    using the values specified in android_binary.manifest_values. The
    merger may be selected by setting the manifest_merger attribute
    on android_binary.
  - The progress message would not clear packages that need to be
    loaded twice.
  - Remove warning for high value of --jobs.
  - Use the correct build configuration for shared native deps during
    Android split transitions.
  - When building ObjectiveC++, pass the flag -std=gnu++11.
  - use xcrun simctl instead of iossim to launch the app for "blaze
    run".
  - Glob arguments 'exclude' and 'exclude_directories' must be named
  - Bazel no longer regards an empty file as changed if its mtime has
    changed.

0.3.0 0.3.0 Release 0.3.0 (2016-06-10)

        Baseline: a9301fa

        Cherry picks:
           + 068a661: GPLv2 + Classpath exception compliance: ship the source code of jformatstring
           + a18add1: Adds the source of the checker framework
           + f6c24de: GPLv2 + Classpath exception compliance: ship the source of checker_framework
           + c95cb5f: Add source for Javac
           + 4017d28: Fix fallout of incorrectly merged review (3921)
           + ff30a73: Turn --legacy_external_runfiles back on by default
           + aeee3b8: Fix delete[] warning on fsevents.cc

        Incompatible changes:

          - The --cwarn command line option is not supported anymore. Use
            --copt instead.

        New features:

          - On OSX, --watchfs now uses FsEvents to be notified of changes
            from the filesystem (previously, this flag had no effect on OS X).
          - add support for the '-=', '*=', '/=', and'%=' operators to
            skylark.  Notably, we do not support '|=' because the semantics
            of skylark sets are sufficiently different from python sets.

        Important changes:

          - Use singular form when appropriate in blaze's test result summary
            message.
          - Added supported for Android NDK revision 11
          - --objc_generate_debug_symbols is now deprecated.
          - swift_library now generates an Objective-C header for its @objc
            interfaces.
          - new_objc_provider can now set the USES_SWIFT flag.
          - objc_framework now supports dynamic frameworks.
          - Symlinks in zip files are now unzipped correctly by http_archive,
            download_and_extract, etc.
          - swift_library is now able to import framework rules such as
            objc_framework.
          - Adds "jre_deps" attribute to j2objc_library.
          - Release apple_binary rule, for creating multi-architecture
            ("fat") objc/cc binaries and libraries, targeting ios platforms.
          - Aspects documentation added.
          - The --ues_isystem_for_includes command line option is not
            supported anymore.
          - global function 'provider' is removed from .bzl files. Providers
            can only be accessed through fields in a 'target' object.

0.2.3 0.2.3 Release 0.2.3 (2016-05-10)

        Baseline: 5a2dd7a

        Extra cherry picks:
           + 068a661: GPLv2 + Classpath exception compliance: ship the source code of jformatstring
           + a18add1: Adds the source of the checker framework
           + f6c24de: GPLv2 + Classpath exception compliance: ship the source of checker_framework
           + c95cb5f: Add source for Javac
           + 4017d28: Fix fallout of incorrectly merged review (3921)

        Incompatible changes:

          - All repositories are now directly under the x.runfiles directory
            in the runfiles tree (previously, external repositories were at
            x.runfiles/main-repo/external/other-repo. This simplifies
            handling remote repository runfiles considerably, but will break
            existing references to external repository runfiles.
            Furthermore, if a Bazel project does not provide a workspace name
            in the WORKSPACE file, Bazel will now default to using __main__
            as the workspace name (instead of "", as previously). The
            repository's runfiles will appear under x.runfiles/__main__/.
          - Bazel does not embed protocol buffer-related rules anymore.
          - It is now an error for a cc rule's includes attribute to point to
            the workspace root.
          - Bazel warns if a cc rule's includes attribute points out of
            third_party.
          - Removed cc_* attributes: abi / abi_deps. Use select() instead.

        New features:

          - select({"//some:condition": None }) is now possible (this "unsets"
            the attribute).

        Important changes:

          - java_import now allows its 'jars' attribute to be empty.
          - adds crunch_png attribute to android_binary
          - Replace --java_langtools, --javabuilder_top, --singlejar_top,
            --genclass_top, and --ijar_top with
            java_toolchain.{javac,javabuilder,singlejar,genclass,ijar}
          - External repository correctness fix: adding a new file/directory
            as a child of a new_local_repository is now noticed.
          - iOS apps are signed with get-task-allow=1 unless building with -c
            opt.
          - Generate debug symbols (-g) is enabled for all dbg builds of
            objc_ rules.
          - Bazel's workspace name is now io_bazel. If you are using Bazel's
            source as an external repository, then you may want to update the
            name you're referring to it as or you'll begin seeing warnings
            about name mismatches in your code.
          - Fixes integer overflow in J2ObjC sources to be Java-compatible.
          - A FlagPolicy specified via the --invocation_policy flag will now
            match the current command if any of its commands matches any of
            the commands the current command inherits from, as opposed to
            just the current command.
          - The key for the map to cc_toolchain_suite.toolchains is now a
            string of the form "cpu|compiler" (previously, it was just "cpu").
          - Fix interaction between LIPO builds and C++ header modules.
          - Ctrl-C will now interrupt a download, instead of waiting for it to
            finish.
          - Proxy settings can now be specified in http_proxy and https_proxy
            environment variables (not just HTTP_PROXY and HTTPS_PROXY).
          - Skylark targets can now read include directories from
            ObjcProvider.
          - Expose parameterized aspects to Skylark.
          - Support alwayslink cc_library dependencies in objc binaries.
          - Import cc_library dependencies in generated Xcode project.

           + 386f242: Automated [] rollback of commit
                      525fa71.

        New features:

          - --extra_entitlements allows passing additional entitlements for
            iOS signing
          - The output of -printconfiguration of proguard is available
            through an implicit "[target_name]_proguard.confg" output of
            android_binary (and
            java_binary).
          - Objective-C compiler information is now available to Skylark.

        Important changes:

          - ProGuard relies on bazel to check to see if the inputs have
            changed.
          - Build the jsonnet tool for the host when cross-compiling.
          - Add ProductType for watch OS 1 extension and application.
          - Restrict file types used for "entitlements" attribute to
            [".entitlements", ".plist"]
          - Restrict file types allowed for "strings" attribute to ".strings".
          - local_repository can take a relative path.
          - Support apple_watch1_extension and apple_watch_extension_binary
            rules for creating watch OS 1 extensions.
          - implement list.insert for skylark rule
          - Enable overriding attributes for Rust binaries.
          - ios_device attribute "xcode", for declaring a specific xcode to
            use when selecting iOS simulators.

0.2.1 0.2.1 Release 0.2.1 (2016-03-21)

        Baseline: 19b5675

        Extra cherry picks:
           + 068a661: GPLv2 + Classpath exception compliance: ship the source code of jformatstring
           + a18add1: Adds the source of the checker framework

           + c95cb5f: Add source for Javac
           + 4017d28: Fix fallout of incorrectly merged review (3921)

        Incompatible changes:

          - Skylark rules that are available from their own repository will
            now issue a warning when accessed through @bazel_tools.
          - Set --legacy_bazel_java_test to off by default. java_test will
            now have a slightly different behaviour, correctly emitting XML
            file but, as a downside, it needs correct declaration of the
            test suite (see bazelbuild#1017).
          - Labels in .bzl files in remote repositories will be resolved
            relative to their repository (instead of the repository the
            Skylark rule is used in).
          - Renamed proto_java_library to java_proto_library.  The former
            is now deprecated and will print out a warning when used.
          - android_sdk now compiles android_jack on the fly from
            android_jar, which means android_jar must be a jar and
            android_jack is now deprecated. The Jack tools (jack, jill,
            resource_extractor) must be specified.
          - Any project that depended on the objc_options rule will be
            broken. Can be fixed by adding attrs (infoplists,copts) directly
            to rules depending on the options.
          - .aidl files correctly require import statements for types

            prints instructions how to spawn a debugging shell inside the
            sandbox.

          - When namespace-sandbox is run with the -D (debug) flag and
            inside a terminal, it spawns a shell inside the sandbox to aid in
            debugging when the sandboxed command fails.
          - Added --artifact to workspace generator for generating workspace
            and build file rules from artifact coodrinates.
          - Specifying --experimental_android_resource_shrinking on the
            command line will enable a resource shrinking pass on
            android_binary targets that already use Proguard.
          - J2ObjC updated to 1.0.1 release.
          - Added "root_symlinks" and "symlinks" parameters to Skylark
            runfiles() method.

            attribute of an ios_test rule.
          - Enable overriding jsonnet binaries and stdlib for Jsonnet rules.
          - mount target of /etc/resolv.conf if it is a symlink.
          - Tests that failed to build because execution was halted no longer
            print their status.
          - Bazel warns if a cc rule's includes attribute contains up-level
            references that escape its package.
          - Add repository_ctx.download and repository_ctx.download_and_extract
            function.

0.2.0 0.2.0 Release 0.2.0 (2016-02-18)

        Baseline: 9e100ac

        Extra cherry picks:
           + 068a661: GPLv2 + Classpath exception compliance: ship the source code of jformatstring
           + a18add1: Adds the source of the checker framework
           + f6c24de: GPLv2 + Classpath exception compliance: ship the source of checker_framework
           + c95cb5f: Add source for Javac
           + 4017d28: Fix fallout of incorrectly merged review (3921)

        Incompatible changes:

          - ObjC compile actions for J2ObjC-translated code now only has
            access to headers from the java deps of the associated original
            java rule.
            These compile actions no longer takes the compiler options
            specified in "copts" attribute on objc_binary/ios_test rules.
            J2ObjC dead code removal (enabled through flag
            "--j2objc_dead_code_removal") now happens *after* ObjC
            compilation.
          - maven_jar no longer supports separate artifact_id, group_id, and
            verison fields. This information should be provided in the
