This release bumps the dependency requirements to use the latest version of SDMetrics.
- Patch release: Bump required version for SDMetrics - Issue #1010 by @katxiao
This release updates the code to use RDT version 1.2.0 and greater, so that those new features are now available in SDV. This changes the transformers that are available in SDV models to be those that are in RDT version 1.2.0. As a result, some arguments for initializing models have changed.
Additionally, this release fixes bugs related to loading models with custom constraints. It also fixes a bug that added NaNs to the index of sampled data when using sample_remaining_columns.

- Update the RDT version to 1.0 - Issue #897 by @pvk-developer
This release brings user friendly improvements and bug fixes on the SDV constraints, to help
users generate their synthetic data easily.
Some predefined constraints have been renamed and redefined to be more user friendly & consistent.
The custom constraint API has also been updated for usability. The SDV now automatically determines
the best handling_strategy to use for each constraint, attempting transform by default and
falling back to reject_sampling otherwise. The handling_strategy parameters are no longer
included in the API.
Finally, this version of SDV also unifies the parameters for all sampling related methods for
all models (including TabularPreset).

This release improves the speed of the GaussianCopula model by removing logic that previously searched for the appropriate distribution to
use. It also fixes a bug that was happening when conditional sampling was used with the TabularPreset.
The rest of the release focuses on making changes to improve constraints including changing the UniqueCombinations constraint to FixedCombinations,
making the Unique constraint work with missing values and erroring when null values are seen in the OneHotEncoding constraint.

This release makes multiple improvements to different Constraint classes. The Unique constraint can now
handle columns with the name index and no longer crashes on subsets of the original data. The Between
constraint can now handle columns with nulls properly. The memory of all constraints was also improved.
Various other features and fixes were added. Conditional sampling no longer crashes when the num_rows argument
is not provided. Multiple localizations can now be used for PII fields. Scaffolding for integration tests was added
and the workflows now run pip check.
Additionally, this release adds support for Python 3.9!

(1) specify multiple columns in Positive and Negative constraints, (2) use the new Uniqueconstraint and
(3) use datetime data with the Between constraint. Additionaly, error messages have been added and updated
to provide more useful feedback to the user.
Besides the added features, several bugs regarding the UniqueCombinations and ColumnFormula constraints have been fixed,
and an error in the metadata.json for the student_placements dataset was corrected. The release also added documentation
for the fit_columns_model which affects the majority of the available constraints.

This release primarily addresses bugs and feature requests related to using constraints for the single-table models.
Users can now enforce scalar comparison with the existing GreaterThan constraint and apply 5 new constraints: OneHotEncoding, Positive, Negative, Between and Rounding.
Additionally, the SDV will now auto-apply constraints for rounding numerical values, and for keeping the data within the observed bounds.
All related user guides are updated with the new functionality.

This release changes the way we sample conditions to not only group by the conditions passed by the user, but also by the transformed conditions that result from them.
- Conditionally sampling on variable in constraint should have variety for other variables - Issue #440 by @amontanez24
This release improves the constraint functionality by allowing constraints and conditions at the same time. Additional changes were made to update tutorials.
- Not able to use constraints and conditions in the same time - Issue #379 by @amontanez24
- Update benchmarking user guide for reading private datasets - Issue #427 by @katxiao
This release broadens the constraint functionality by allowing for the ColumnFormula
constraint to take lambda functions and returned functions as an input for its formula.
It also improves conditional sampling by ensuring that any id fields generated by the
model remain unique throughout the sampled data.
The CTGAN model was improved by adjusting a default parameter to be more mathematically
correct.
Additional changes were made to improve tutorials as well as fix fragile tests.
- Tutorials test sometimes fails - Issue #355 by @fealho

This release brings new privacy metrics to the evaluate framework which help to determine
if the real data could be obtained or deduced from the synthetic samples.
Additionally, now there is a normalized score for the metrics, which stays between 0 and 1.
There are improvements that reduce the usage of memory ram when sampling new data. Also there
is a new parameter to control the reject sampling crash, graceful_reject_sampling, which if
set to True and if it's not possible to generate all the requested rows, it will just issue a
warning and return whatever it was able to generate.
The Metadata object can now be visualized using different combinations of names and details,
which can be set to True or False in order to display only the table names with details or
without. There is also an improvement on the validation, which now will display all the errors
found at the end of the validation instead of only the first one.
This version also exposes all the hyperparameters of the models CTGAN and TVAE to allow a more
advanced usage. There is also a fix for the TVAE model on small datasets and it's performance
with NaN values has been improved. There is a fix for when using
UniqueCombinationConstraint with the transform strategy.

In this version a new family of models for Synthetic Time Series Generation is introduced
under the sdv.timeseries sub-package. The new family of models now includes a new class
called PAR, which implements a Probabilistic AutoRegressive model.
This version also adds support for composite primary keys and regex based generation of id fields in tabular models and drops Python 3.5 support.

The reversible transformation is handled by the GaussianCopulaTransformer recently added to RDT.
- Add CopulaGAN Model - Issue #202 by @csala
This release moves the models and algorithms related to generation of synthetic
relational data to a new sdv.relational subpackage (Issue #198)
As part of the change, also the old sdv.models have been removed and now
relational model is based on the recently introduced sdv.tabular models.
In this release the sdv.evaluation module has been reworked to include 4 different
metrics and in all cases return a normalized score between 0 and 1.
Included metrics are:
cstestkstestlogistic_detectionsvc_detection
This release fixes a couple of minor issues and introduces an important rework of the User Guides section of the documentation.
- Error Message: "make sure the Graphviz executables are on your systems' PATH" - Issue #182 by @csala
- Anonymization mappings leak - Issue #187 by @csala
In this release SDV gets new documentation, new tutorials, improvements to the Tabular API and broader python and dependency support.
Complete list of changes:
- New Documentation site based on the
pydata-sphinx-theme. - New User Guides and Notebook tutorials.
- New Developer Guides section within the docs with details about the SDV architecture, the ecosystem libraries and how to extend and contribute to the project.

This release introduces a new concept of Constraints, which allow the user to define
special relationships between columns that will not be handled via modeling.
This is done via a new sdv.constraints subpackage which defines some well-known pre-defined
constraints, as well as a generic framework that allows the user to customize the constraints
to their needs as much as necessary.
- Support for Constraints - Issue #169 by @csala
This release introduces a new subpackage sdv.tabular with models designed specifically
for single table modeling, while still providing all the usual conveniences from SDV, such
as:
- Seamless multi-type support
- Missing data handling
- PII anonymization
Currently implemented models are:
- GaussianCopula: Multivariate distributions modeled using copula functions. This is stronger version, with more marginal distributions and options, than the one used to model multi-table datasets.
