+Changes to integration testing
++++++++++++++++++++++++
+
+The "out-of-process" nodes spawned through Driver DSL (see :doc:`tutorial-integration-testing`) will no longer accidentally contain your CorDapps on their application classpath. The list of items that will be automatically filtered out include:
+
+* Directories (only regular files are allowed)
+* Jars with Maven classifiers ``tests`` or ``test``
+* Jars with any Cordapp attributes in their manifests (any of those listed in :doc:`cordapp-build-systems` or ``Target-Platform-Version`` and ``Min-Platform-Version`` if both are present)
+* Jars with the ``Corda-Testing`` attribute in their manifests. The manifest of the following artifacts has been updated to include the ``Corda-Testing`` attribute:
+
+	* ``corda-node-driver``
+	* ``corda-test-utils``
+	* ``corda-test-common``
+	* ``corda-test-db``
+	* ``corda-mock``
+
+* Files whose names start with ``corda-mock``, ``junit``, ``testng`` or ``mockito``
+
+Some of your existing integration tests might implicitly be relying on the presence of the above files, so please keep this in mind when upgrading your version of Corda.
