 Magento Functional Testing Framework Changelog
 ================================================
+3.1.0

+
+### Enhancements
+
+* Customizability
+  * Introduced the new `return` action that allows action groups to return a value. See the [actions page](./docs/test/actions.md#return) for details.
+  * Introduced new MFTF command that invokes `vendor/bin/codecept run`. See the [mftf page](./docs/commands/mftf.md#codeceptrun) for details.
+
+* Usability
+  * Introduced new action `pause`, to invoke codeception interactive pause for debugging during test execution. See the [Interactive Pause](./docs/interactive-pause.md) page for details.
+  * Introduced a new `.env` configuration option `ENABLE_PAUSE`, to enable the new pause feature.
+
+* Maintainability    
+  * Added a new static check that checks for the usage of the `pause` action. See the [command page](./docs/commands/mftf.md#static-checks) for details.
+
+* Modularity   
+  * MFTF now supports the use of actions from multiple modules within suites.
