Work in progress

New asynchronous API

New AsyncSession (acquired from DaoSession.startAsyncSession()) provides most operations for DAOs, Queries, and transactions in a asynchronously variant
AsyncOperations are processed in order by a background thread
waitForCompletion methods for AsyncSession and AsyncOperations
AsyncOperationListener for asynchronous callback when operations complete
Asynchronous operations can be merged in single transactions (details follow)
Added raw SQL queries returning a Query object (LazyList support etc.)
