Release Notes: Queries can now be compiled, preparing them for execution with varying parameter values. For JDBC databases, this will provide prepared statement-like functionality. For other datastores, it will simply make query reuse simpler. DataSet index caching has been implemented, making lookup by column or by "select item" faster and constant-time.

Release Notes: This release provided full support for CRUD operations on JDBC databases, CSV files, Excel spreadsheets, and NoSQL stores. CREATE TABLE, DROP TABLE, UPDATE, and DELETE FROM operations were added. Support for LIST and MAP column types (common in NoSQL stores) was added. Awareness of primary key columns was implemented (especially useful for UPDATE operations). Support for plain Java collections as datastores (LINQ style) was added. Full support for CouchDB databases was provided. Several maturing improvements were made in the API's syntax and semantics.

Release Notes: This release introduces an interceptor layer for adapting and monitoring any query or update to your data. It greatly improves JDBC insert performance by using batch inserts instead of regular statements. It sanitizes the type conversion API to use the new interceptor layer.
