Database abstraction broken up into controller, connector, query builder, and schema manager, each independently configurable via YAML / Injector Creation of new DBQueryGenerator for database specific generation of SQL Support for parameterised queries, move of code base to use these over escaped conditions Refactor of SQLQuery into separate query classes for each of INSERT UPDATE DELETE and SELECT Support for PDO Installation process upgraded to use new ORM SS_DatabaseException created to handle database errors, maintaining details of raw sql and parameter details for user code designed interested in that data. Renamed DB static methods to conform correctly to naming conventions (e.g. DB::getConn -> DB::get_conn) 3.2 upgrade docs Performance Optimisation and simplification of code to use more concise API API Ability for database adapters to register extensions to ConfigureFromEnv.php
