greenDAO is a light & fast ORM solution for Android that maps objects to SQLite databases. Being highly optimized for Android, greenDAO offers great performance and consumes minimal memory.

New features ahead for the brave: documentation and test coverage may be lacking. Give it a shot if you dare. API may change in the future.
- 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.)
EventBus is a central publish/subscribe bus for Android with optional delivery threads, priorities, and sticky events. A great tool to decouple components (e.g. Activities, Fragments, logic components) from each other.
greenrobot-common is a set of utility classes and hash functions for Android & Java projects.

- Added Flag for AsyncOperation to track the caller's stacktrace (useful for debugging)
- Fix schema version >= 1000
- Fixed building defect DeleteQuery for tables ending with character 'T' (bug introduced in 1.3.3)
- Prepared Fast Cursor for API level 19
- Fixed leaked statement in DeleteQuery
- Because of an issue with ApplicationTestCase, the base test class DbTest does not extend this class anymore. Note: This refactoring may require you to adjust some test classes if your tests depend on DbTest or its subclasses.
- Redeployment of 1.3.3 artifacts without some old class leftovers
- Fixed a memory leak affecting Query class that was introduced in 1.3.0 (#93)
- Fixed a rare race condition that can lead to "Entity is detached from DAO context" DaoException (#101)
- Fixed building CountQueries with combined AND/OR conditions
- Some secret inoffical work in progress
- Don't use Gradle's "compile" dependency scope
- Reworked internal locking of insert/update/delete methods
- Fixed potential deadlocks when transactions are executed concurrently to one of the various insert/update/delete calls
- Reworked queries to be used without locking, query instances are now bound to their owner thread (breaking change!)
- Relations use the new lock-free query API
- Query classes were moved into the new query subpackage (breaking change!)
- Introduced Gradle build scripts for DaoCore and DaoGenerator projects
- Maven artifacts are pushed to Maven Central starting with this version
- Added two packages for classes used internally (identityscope and internal)
- Added new deleteByKeyInTx DAO method to efficiently delete multiple entities using their keys
- Added some checks to throw exceptions with nicer messages telling what's wrong
- Added Travis CI
- Limited support of String PKs (no relations using String FKs yet)
- Fixed index creation (please update your schema)
- Added CountQuery for creating SELECT COUNT (*) queries with QueryBuilder
- Added getDatabase in DaoMaster, DaoSession, and Dao
- Added insertOrReplaceInTx in Dao
- Added deleteInTx in Dao
- Added autoincrement() creating AUTOINCREMENT PKs
- Made DAOs and DaoSessions in active entities transient (allows serialization of entities)
- Minor fixes
- Demo projects works with ADT 17 (moved greendao.jar into libs)
- CREATE/DROP TABLE may be skipped for entity types: This allows having multiple entity types operate on the same table
- Minor improvements
- Added NOT IN condition for QueryBuilder
- Fix for Roboelectric (Issue #22)
- Minor fix (Issue #5)
- DeleteQuery for bulk deletes
- Entities may implement Java interfaces
- Entities may extend a Java class
- Added LIMIT and OFFSET support for QueryBuilder and Query
- Convenience methods to add named relationships
- SQL scripts are executed in a transaction by default
- Fixed queries with special column names (SQL keywords)
- Changed default names for to-many relations to end with "List"
- ORDER BY uses LOCALIZED collation for strings by default
- Fixed generation of to-many relations
- Fixed generated import statements when entities/DAO are not in the same package
- To-many relations (lazily loaded on the entities)
- To-many relations with custom join properties
- Active entities can be updated, refreshed, and deleted directly
- Significant performance improvements (faster identity scope, faster database result parser)
- "Keep sections" for custom code in entities were added that won't be overwritten during code generation
- Other minor improvements
