Incompatible changes:

• Depsets (former sets) are converted to strings as "depset(...)"
  instead of
  "set(...)".
• Using --symlink_prefix is now applied to the output
  symlink (e.g. bazel-out) and the exec root symlink (e.g.
  bazel-workspace).
• Bazel now uses the test's PATH for commands specified as
  --run_under; this can affect users who explicitly set PATH to
  a more
  restrictive value than the default, which is to forward the
  local PATH
• It's not allowed anymore to compare objects of different types
  (i.e. a string to an integer) and objects for which comparison
  rules are not
  defined (i.e. a dict to another dict) using order operators.

New features:

• environ parameter to the repository_rule function let
  defines a list of environment variables for which a change of
  value
  will trigger a repository refetching.

Important changes:

• android_ndk_repository now supports Android NDK R13.
• Android resource shrinking is now available for android_binary
  rules. To enable, set the attribute 'shrink_resources = 1'. See
  https://bazel.build/versions/master/docs/be/android.html#android_b
  inary.shrink_resources.
• resolve_command/action's input_manifest return/parameter is now
  list
• For increased compatibility with environments where UTS
  namespaces are not available, the Linux sandbox no longer hides
  the hostname of the local machine by default. Use
  --sandbox_fake_hostname to re-enable this feature.
• proto_library: alias libraries produce empty files for descriptor
  sets.
• Adds pkg_rpm rule for generating RPM packages.
• Allow CROSSTOOL files to have linker flags specific to static
  shared libraries.
• Make it mandatory for Java test suites in bazel codebase, to
  contain at least one test.
• Support for Java 8 lambdas, method references, type annotations
  and repeated annotations in Android builds with
  --experimental_desugar_for_android.
• Removed .xcodeproj automatic output from objc rules. It can still
  be generated by requesting it explicitly on the command line.
• Flips --explicit_jre_deps flag on by default.
• Activate the "dbg", "fastbuild", and "opt" features in the objc
  CROSSTOOL.
• Remove support for configuring JDKs with filegroups; use
  java_runtime and java_runtime_suite instead
• android_ndk_repository api_level attribute is now optional. If not
  specified, the highest api level in the ndk/platforms directory
  is used.

Classpath exception. Those installers should always be redistributed along with
