## 0.12.1.0 -- 2019-05-08

* Bring over functions from @mpickering's hie-bios.
  So `LspFuncs` now includes

```haskell
    , persistVirtualFileFunc       :: !(J.Uri -> IO FilePath)
    , reverseFileMapFunc           :: !(IO (FilePath -> FilePath))
 ```

* Fix exception on empty filepaths

* Migrate some utility functions from `haskell-ide-engine`, for the
  benefit of other language servers.
  - `rangeLinesFromVfs`
  - `PosPrefixInfo(..)`
  - `getCompletionPrefix`

* Remove `HoverContentsEmpty`. It is unnecessary, and generated
  illegal JSON on the wire.

* Add support for cancellable requests within `withProgress` and

  `unliftio` if you need to use them with a Monad transformer stack)
