 # Release Notes
 
+## 1.8.0 - 2023-12-05
+
+This release adds support for the new Diagnostic Report from SDMetrics. This report calculates scores for three basic but important properties of your data: data validity, data structure and in the multi table case, relationship validity. Data validity checks that the columns of your data are valid (eg. correct range or values). Data structure makes sure the synthetic data has the correct columns. Relationship validity checks to make sure key references are correct and the cardinality is within ranges seen in the real data.
+
+Additionally, a few bugs were fixed and functionality was improved around synthesizers. It is now possible to access the loss values for the `TVAESynthesizer` and `CTGANSynthesizer` by using the `get_loss_values` method. The `get_parameters` method is now more detailed and returns all the parameters used to make a synthesizer. The metadata is now capable of detecting some common pii sdtypes. Finally, a bug that made every parent row generated by the `HMASynthesizer` have at least one child row was patched. This should improve cardinality.

+
+### Bugs Fixed

 ## 1.7.0 - 2023-11-16
 
 This release adds an alert to the `CTGANSynthesizer` during preprocessing. The alert informs the user if the fitting of the synthesizer is likely to be slow on their schema. Additionally, it is now possible to enforce that sampled datetime values stay within the range of the fitted data!
