Version 0.3.0

Changes since 0.2.3:

• pex_pytest rules now support the tags attribute
• python-requests has been updated to 2.11.1
• rules_pex is now compatible with Bazel 0.3.2 and 0.4.0, as well as XCode 8.x on MacOS.
• Set PEX_ROOT during builds to avoid pex writing outside of the build sandbox
• Try to use hard linking before falling back to a copy operation for the final output binary
• It should now be possible to depend on pex_* and py_* rules defined in external repositories
• pex_pytest now sets TEST_TMPDIR and PEX_ROOT at runtime to avoid pex trying to write to $HOME
• Make better use of Bazel's runfiles mechanism to collect transitive source and data files. The implementation is considerably simpler now, and this should improve cross-compatibility with the the built-in bazel py_binary/py_library/py_test rules.
• Switched to JSON instead of a bespoke textual manifest format to pass data from skylark to pex_wrapper at build time.
• pex_pytest now marks its test runner script as testonly so bazel will allow dependencies on other testonly rules.

Version 0.2.3

New features:

• pex_pytest rule now generates fancy junit XML output for Bazel, with
  full python class names and per-test timing data.
• Support for bazel 0.3.1

Bugfixes:

• Embedding data files from external repositories into a pex_binary
  should actually work now.

Other changes:

• Updated pytest from 2.9.2 to 3.0.2
• Removed a few unnecessary native.bind targets
• Initial wrapper bootstrapping is more reliable than before, and
  slightly faster.
