v1.10.0 - 2024-02-15

This release adds multiple improvements to handling premium transformers and column relationships, including using premium transformers even if the PII flag is set to true. Additionally, the SDV now warns users to save the metadata after auto-detection has been used. Semantic sdtype detection has also been improved to tokenize column names to prevent unexpected substring matches.

This release also fixes a few warning bugs and fixes an issue that would cause metadata.to_dict to fail for metadata loaded from older versions of the SDV. A few synthesizer bugs were also resolved. The quality of the sequence_index for the PARSynthesizer has been improved, and an issue that would cause CTGANSynthesizer, TVAESynthesizer, and CopulaGANSynthesizer to crash if all columns were to be generated from scratch has been fixed.
