 ## Unreleased
 ### Added
- - Added new `Values` term
+ - Added `UUID` term
+ - Added `Values` term
  - Added `IncludeInitial` to `ChangesOpts`
  - Added `UseJSONNumber` to `ConnectOpts` which changes the way the JSON unmarshal works when deserializing JSON with interface{}, it's preferred to use json.Number instead float64 as it preserves the original precision.
 
 ### Changed
  - Timezones from `time.Time` are now stored in the database, before all times were stored as UTC. To convert a go `time.Time` back to UTC you can call  `t.In(time.UTC)`.
+ - Improved host selection to use `hailocab/go-hostpool` to select nodes based on recent responses and timings.
