## 0.1.4.0

Major changes:

* You now have more control over how GHC versions are matched, e.g. "use exactly this version," "use the specified minor version, but allow patches," or "use the given minor version or any later minor in the given major release." The default has switched from allowing newer later minor versions to a specific minor version allowing patches. For more information, see [#736](https://github.com/commercialhaskell/stack/issues/736) and [#784](https://github.com/commercialhaskell/stack/pull/784).
* Support added for compiling with GHCJS
* stack can now reuse prebuilt binaries between snapshots. That means that, if you build package foo in LTS-3.1, that binary version can be reused in LTS-3.2, assuming it uses the same dependencies and flags. [#878](https://github.com/commercialhaskell/stack/issues/878)

Other enhancements:

* Added the `--docker-env` argument, to set environment variables in Docker container.
* Set locale environment variables to UTF-8 encoding for builds to avoid "commitBuffer: invalid argument" errors from GHC [#793](https://github.com/commercialhaskell/stack/issues/793)
* Enable translitation for encoding on stdout and stderr [#824](https://github.com/commercialhaskell/stack/issues/824)

* Added the `ghc-options` field to stack.yaml [#796](https://github.com/commercialhaskell/stack/issues/796)
* Added the `extra-path` field to stack.yaml
* Code page changes on Windows only apply to the build command (and its synonyms), and can be controlled via a command line flag (still defaults to on) [#757](https://github.com/commercialhaskell/stack/issues/757)
* Implicitly add packages to extra-deps when a flag for them is set [#807](https://github.com/commercialhaskell/stack/issues/807)
