 # Changelog
 
+## 4.0.0
+* Changed connection setup to just use a config object - the appropriate adapter object is created by the library.
+* Removed mysql adapter, as mysql2 is very similar and does proper prepared statements
+
 ## 3.2.0
 * Added public `query` method for making arbitrary sql calls
 * Added back tests for `node-firebird` adapter. Using this adapter with promises is not currently supported.
