PyRel 1.10.0 adds support for stddev_samp() in queries, improves rai doctor:report diagnostics, and fixes query, import, and Snowflake deployment issues.

How to install this version

For the latest installation instructions, see Start building with PyRel.

New Features and Enhancements

Section titled “New Features and Enhancements”

  • You can now use stddev_samp() in PyRel queries to compute sample standard deviation. Before 1.10.0, you had to compute it outside PyRel or build it from lower-level operations.

  • rai doctor:report now provides more detail when you troubleshoot deployment-role issues or share environment details with support. It adds Snowflake task execute privilege diagnostics and richer version metadata.

Bug Fixes

Section titled “Bug Fixes”

  • Imports for the prescriptive and predictive reasoner packages now work on Python 3.11 or later. Before this fix, imports could fail because of an invalid dataclass default.

  • SQL-backed select() queries no longer return unexpected duplicate rows when you use distinct().

  • Some Snowflake deployments no longer fail when models read Snowflake-backed data sources through CDC. Before this fix, deployments could materialize those inputs as unsupported dynamic tables instead of CDC-compatible tables with change tracking.
