_Release Date: January 16, 2024_ This release includes some quality improves, bug fixes and sets up some foundations for future optimizations. ⚡ **Improved Data Cardinality.** With our new preprocessing methods, you’ll now see improved data quality for [parent/child cardinality](https://docs.sdv.dev/sdv/multi-table-data/evaluation/data-quality#whats-included) in multi-table datasets. For example, if 40% of the real parents rows have 1 child while 60% have 2+ children, then the same will be true in the synthetic data. 💕 **Specify Column Relationships.** Do you have multiple columns that encode the same concept? Now, you can [specify these column relationships](https://docs.sdv.dev/sdv/multi-table-data/data-preparation/multi-table-metadata-api#add_column_relationship) directly in the metadata. In this release, you can annotate when multiple columns together represent a single physical mailing address. More concepts are coming soon! 🧱 **Foundational Codebase Changes.** Behind-the-scenes, we’ve been making a few changes to the way our codebase is compiled. There are no changes to the Python API — this is just to help us make optimizations in the future. Please feel free to retry our existing features and let us know if you notice any issues! _Additional updates_ - _You can now opt to create random, anonymized data from any of the options in the Faker library. Even complex concepts such as [currency](https://faker.readthedocs.io/en/master/providers/faker.providers.currency.html)._ - _The [Inequality constraint](https://docs.sdv.dev/sdv/reference/constraint-logic/predefined-constraint-classes/inequality) now works correctly for datetime columns, especially with complex date formats._ - _The [CTGANSynthesizer](https://docs.sdv.dev/sdv/single-table-data/modeling/synthesizers/ctgansynthesizer) now works with the FixedCombinations constraint_.
