 * Docker: when Docker Engine is remote, don't run containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194)
 * Docker: `set-user` option to enable/disable running containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194)
 * Custom Setup.hs files are now precompiled instead of interpreted. This should be a major performance win for certain edge cases (biggest example: [building Cabal itself](https://github.com/commercialhaskell/stack/issues/1041)) while being either neutral or a minor slowdown for more common cases.
+* `stack test --coverage` now also generates a unified coverage report for multiple test-suites / packages.  In the unified report, test-suites can contribute to the coverage of other packages.
