Incompatible changes:

- ctx.fragments.apple.{xcode_version,ios_minimum_os} is not

supported anymore. The same information is accessible through the

target @bazel_tools//tools/osx:current_xcode_config: point an

implicit attribute to it (i.e.

attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co

nfig")) then use

ctx.attr._xcode_config[apple_common].XcodeVersionConfig].

- ctx.fragments.apple.minimum_os_for_platform_type is not supported

anymore. The same information is accessible through the target

@bazel_tools//tools/osx:current_xcode_config: point an implicit

attribute to it (i.e.

attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co

nfig")) then use

ctx.attr._xcode_config[apple_common].XcodeVersionConfig].minimum_o

s_for_platform_type .

- ctx.fragments.apple.sdk_version_for_platform is not supported

anymore. The same information is accessible through the target

@bazel_tools//tools/osx:current_xcode_config: point an implicit

attribute to it (i.e.

attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co

nfig")) then use

ctx.attr._xcode_config[apple_common].XcodeVersionConfig].sdk_versi

on_for_platform .

- --javabase=<absolute path> and --host_javabase=<absolute path>

are not supported anymore. If you need this functionality

java_runtime_suite(name="suite", default=":runtime")

java_runtime(name="runtime", java_home=<path to the JDK>) is an

alternative.

- The flag --incompatible_descriptive_string_representations is no

longer available, old style string representations of objects are

not supported

anymore.

- The flag --incompatible_disallow_set_constructor is no longer

available, the deprecated `set` constructor is not available

anymore.

- += on lists now mutates them. `list1 += list2` is now equivalent

to `list1.extend(list2)` and not equivalent to `list1 = list1 +

list2` anymore.

- the target_apple_env and apple_host_system_env methods on

ctx.fragments.apple are not supported anymore. The same

information is accessible through apple_common.target_apple_env

and apple_common.apple_host_system_env . They need the Xcode

configuration as an argument, which can be obtained by declaring

an implicit dependency on it (i.e.

attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_co

nfig")) and then calling e.g.

apple_common.apple_host_system_env(ctx.attr._xcode_config[apple_co

mmon.XcodeVersionConfig]).

- C++ toolchain identifiers are not in the name of the output

directory anymore.

- Selecting on "xcode_version" and

"{ios,tvos,macos,watchos}_sdk_version" is not supported anymore.

What was config_setting(values={"$FOO_version": $VALUE}) is now

config_setting(flag_values={"@bazel_tools//tools/osx:$FOO_version_

flag": $VALUE}).

- Selecting on "xcode_version" and

"{ios,tvos,macos,watchos}_sdk_version" is not supported anymore.

New features:

- runfiles, sh: Shell scripts may now depend on

//src/tools/runfiles:runfiles_sh_lib and source runfiles.sh. The

script defines the `rlocation` function which returns runfile

paths on every platform.

- In addition to $(location), Bazel now also supports $(rootpath)

to obtain

the root-relative path (i.e., for runfiles locations), and

$(execpath) to

obtain the exec path (i.e., for build-time locations)

Important changes:

- android_binary now supports custom debug keys via the debug_key

attribute.

- Updated Android proguard to 5.3.3. It now works with android-24+.

- --experimental_use_parallel_android_resource_processing and

--experimental_android_use_nocompress_extensions_on_apk are

removed. These features are fully rolled out.

- Fixes #2574

- Fixes #3834

- Enable experimental UI by default.

- .

RELNOTES: None.

RELNOTES: No.

- Add memory profiler.

- [Bazel] {java,cc}_proto_library now look for dependencies in

@com_google_protobuf, instead of in @com_google_protobuf_$LANG

- Improved merge.sh script in cookbook.

- Fixing regression to --experimental_remote_spawn_cache

- Support for linker scripts in NativeDepsHelper (e.g.,

android_binary)

- Skylark semantics flags now affect WORKSPACE files and repository

rules.

- ctx.outputs.executable is deprecated. Use DefaultInfo(executable

= ...) instead.

- Update "mirror.bazel.build" urls to use https.

- Improve --config logging when --announce_rc is present.

- Document interaction between test_suite and target exclusions

- Replace version numbers for Bazel installers with "<version>"

(because this will change often)

- Published command lines should have improved lists of effective

options.

- --incremental_dexing_binary_types has been removed. All builds

are supported by incremental dexing (modulo proguard and some

blacklisted dx flags).

- Document --host_javabase, --host_java_toolchain
