  `-XepOpt:NullAway:CheckOptionalEmptiness=true` to enable (experimental) support for `Optional` emptiness.
* Improved (partial but sound-er) varargs support (#291).
* Refactor for ErrorMessage class use (#284).
* Custom path to Optional class for Optional emptiness handler (#288).
* Add support for methods taking literal constant args in Access Paths. (#285).

Version 0.6.6
---------------
This only adds a minor library fix supporting Guava's Preconditions.checkNotNull with an error message 
argument (#283)

Version 0.6.5
---------------

Version 0.6.4
---------------
* Initial support for JDK 11 (#263).  Core NullAway should be working, but JarInfer does not yet work.

Version 0.2.0

  the spec.  This may also cause new warnings in code that was
  previously NullAway-clean.
