 Change Log
 =========
 
+Version 0.3.0 *(2015-08-31)*
+----------------------------
+
+ * Transactions are now exposed as objects instead of methods. Call `newTransaction()` to start a
+   transaction. On the `Transaction` instance, call `markSuccessful()` to indicate success and
+   `end()` to commit or rollback the transaction. The `Transaction` instance implements `Closeable`
+   to allow its use in a try-with-resources construct. See the `newTransaction()` Javadoc for more
+   information.
+ * `Query` instances can now be turned directly into an `Observable<T>` by calling `asRows` with a
+   `Func1<Cursor, T>` that maps rows to a type `T`. This allows easy filtering and limiting in
+   memory rather than in the query. See the `asRows` Javadoc for more information.
+ * `createQuery` now returns a `QueryObservable` which offers a `mapToList` operator. This operator
+   also takes a `Func1<Cursor, T>` for mapping rows to a type `T`, but instead of individual rows it
+   collects all the rows into a list. For large query results or frequently updated tables this can
+   create a lot of objects. See the `mapToList` Javadoc for more information.
+ * New: Nullability, `@CheckResult`, and `@WorkerThread` annotations on all APIs allow a more useful
+   interaction with lint in consuming projects.

 Since queries are just regular RxJava `Observable` objects, operators can also be used to
 control the frequency of notifications to subscribers.
