 # History
 
+## v0.3.0 - 2020-12-18
+
+In this release we add a new TVAE model which was presented in the original CTGAN paper.
+It also exposes more hyperparameters and moves epochs and log_frequency from fit to the constructor.
+
+A new verbose argument has been added to optionally disable unnecessary printing, and a new hyperparameter
+called `discriminator_steps` has been added to CTGAN to control the number of optimization steps performed
+in the discriminator for each generator epoch.
+
+The code has also been reorganized and cleaned up for better readability and interpretability.
+
+Special thanks to @Baukebrenninkmeijer @fealho @leix28 @csala for the contributions!
