Release Summary This release includes a number of performance improvements, most notably improving CPU utilization and throughput for standalone data synthesis and validation using chunk scaling. It also includes official support for Python 3.12 and removes support for Python 3.8. This release fixes installation issues related to TLS and secret management for airgap installations, addresses issues found when upgrading trainee versions, improves privacy when synthesizing data sets that include columns that are hard to predict, and fixes bugs around random number seeds and react calls with case weights.

Synthesizer Improvements Greatly improved CPU utilization and throughput for chunk scaling when running standalone. Strengthened privacy by improved difference evaluation of nominal features values, particularly those that have low predictability, taking advantage of the similarity to increase the entropy of synthesized values and decreasing the amount that the differences of values when considering if the synthetic case is sufficient to be considered a new with regard to the original data. Performance improvements and reduction of memory use. Fixes Removed documentation for previously removed feature attribute time_delta_format. Validator No changes. Validator Enterprise Improvements Performance improvements and reduction of memory use. Howso Engine Breaking Changes Support is officially ended for Python 3.8. Improvements Python 3.12 is officially supported. Improved distance evaluation for nominal features, particularly when the nominal values are not well predictable. Performance improvements and reduction of memory use. Removed smallest fractional p value for targeted analyze, as recent improvements in surprisal space as distances removed the performance benefits brought by the small fractional p value. Improved data ablation efficiency by automatically ablating duplicate cases. Added MCC (Matthews Correlation Coefficient) to prediction statistics. Improved error messages for misconfigured setups. Fixes Fixed rare distance accuracy issue with json, yaml, code, and string distances when comparing against null values. Removed documentation for previously removed feature attribute time_delta_format. Fixed bug where discriminative reacts with case weights would sometimes yield incorrect results. Fixed bug where random seeds would not be changed between runs when loading a new trainee in caml format via the common Python/C-API method. Howso Platform Improvements Upgraded platform components to resolve CVE-2024-1135. Added the trainee worker initContainer resources configuration to the helm chart values. Fixes Fixed issue where the TLS sidecar image was missing from howso-platform kots airgap bundles. Fixed issue where the image pull secret was missing from airgap bundles. Fixed miscellaneous issues with the trainee archive/migration process. Synthesizer Recipes No changes.

Howso Engine Recipes No changes.

Known Issues The Synthesizer UI, currently in beta, currently only supports smaller data sets, and does not expose all of the functionality of Synthesizer. These limitations will be addressed in future releases. When using the Howso Platform and performing reacts with a larger number of features (in the realm of one hundred or more) and requesting significant data from details (e.g., a large number of boundary and similar cases), the scale of the message sizes returned may be notably large and have an adverse effect on performance and memory. This is an edge case that can be worked around by limiting what is requested simultaneously from each react. This is aimed to be fixed in late Q2 or early Q3 of 2024.
