## 0.2.0

### Breaking Changes
* Make `STACK_BUILD_OPTIONS` and `CABAL_CONFIGURE_OPTIONS` append to the
  existing build/configure options instead of overriding them.
* Do not enforce specific `stack` version in CI configs - this is done to avoid
  failures due to github API limits when upgrading or downgrading.

### Bug Fixes
* Avoid build failures in cases when `cabal-install` has to be installed and
  its dependencies may conflict with the current project dependencies.

### Enhancements
* Better documentation in travis and appveyor configs
* Reduce the number of builds in default config from 11 to 6

## 0.1.1
