v1.14.0 - 2024-06-13

This release provides a number of new features. A big one is that it adds the ability to fit the HMASynthesizer on disconnected schemas! It also enables the PARSynthesizer to work with constraints in certain conditions. More specifically, the PARSynthesizer can now handle constraints as long as the columns involved in the constraints are either exclusively all context columns or exclusively all non-context columns.

Additionally, a verbose parameter was added to the TVAESynthesizer to get a more detailed progress bar. Also, a bug was corrected that renamed the file_path parameter in the ExcelHandler.read() method to filepath as specified in the official SDV docs.
