+title: Cayenne 4.1 Final Released
+date: 2020-07-21T12:00:00+03:00
+---
+
+Apache Cayenne team is really glad to announce a final (general availability)
release of _Cayenne 4.1_.
+
+Here is a recap of all great changes made since 4.0:
+
+- New field-based data objects (see {{% jira 2330 %}}),
+ that are **much faster** to read and write, while **significantly** reducing
the app memory footprint.
+
+- Dependency-free Cayenne core. No more velocity or commons-collections
compile dependencies. Only "slf4j-api" is required in the base config.
+
+- New extensible project XML structure.
+
+- New reverse engineering UI in Cayenne Modeler, that is much more intuitive
and customizable,
+more over configuration is now saved so you can evolve it with your model and
perform reverse engineering in one click.

+</p>
+
+- User controlled transaction propagation logic and isolation level.
+
+```
+ TransactionManager manager =
runtime.getInjector().getInstance(TransactionManager.class);
+ TransactionDescriptor descriptor = new TransactionDescriptor(
+ Connection.TRANSACTION_SERIALIZABLE, // set transaction isolation
to SERIALIZABLE
+ TransactionPropagation.REQUIRES_NEW // require new transaction
for every operation
+ );
+ manager.performInTransaction(() -> {
+ // perform some DB operations...
+ return null;
+ }, descriptor);
+
+```
+
+- And a numerous minor fixes and improvements.
+
