+PyBuilder 0.13.3 introduced two new features:
+
+* Resettable integration test Python virtual environment.
+* The activated build environments can now be introspected from the project.
+
+<!--more-->
+
+### Resettable Integration Test Environment
+
+Sometimes an integration test modifies its virtual environment by, for example, installing or upgrading packages. This,
+naturally, has potential to affect other tests running after it, compromising repeatability.
+
+Setting `integrationtest_python_env_recreate` property to `True` will ensure that the integration test virtual
+environment is recreated and repopulated by the PyBuilder prior to every test.
+
+PyBuilder uses this feature
+[here](https://github.com/pybuilder/pybuilder/blob/de74b167c6c8ef679ed1f1a1ff79349d004c5785/build.py#L157)
+to test itself.
+
+### Build Environment Introspection
+
+PyBuilder allows specifying an environment option (using `-E`) to modify build behavior based on the external
+environment in which the build is running. This is most useful when activating plugins that are only useable in the CI
+or other special-purpose environments
+(
+e.g. [coveralls](https://github.com/pybuilder/pybuilder/blob/de74b167c6c8ef679ed1f1a1ff79349d004c5785/src/main/python/pybuilder/plugins/python/coveralls_plugin.py#L32))
+.
+
+Now PyBuilder also allows users to introspect activated environments by retrieving `project.environments`.
+
+For more details please see the [v0.13.3 release notes](/release-notes/v0.13.x#version-0133).
