+- Training can now be launched using the most recent model configuration from a project.
+- Enabled non-interactive mode capability, allowing for automation or operations without manual inputs.
+- Added new validation :py:meth:`Project.is_trainable()<ansys.simai.core.data.projects.Project.is_trainable>` to verify if the project meets all minimum requirements for training.
+- Added new method :py:meth:`Project.get_variables()<ansys.simai.core.data.projects.Project.get_variables>` to get all available variables used for a model's inputs and outputs.
+- Fixed bug where a subset of training data could not be pulled. A subset of training data is now correctly retrieved.
