    Bug

    [PUBDEV-5102] - In Flow, the metalearner_fold_column option now correctly displays a drop-down of column names. 🏁 [PUBDEV-5282] - Fixed an issue that caused data import and building models fail when using Flow in IE 11.1944 on Windows 10 Enterprise. [PUBDEV-5323] - Stacked Ensemble no longer fails when using a grid or list of GLMs as the base models. 🛠 [PUBDEV-5330] - Fixed an issue that caused an error when during Parquet data ingest. 🗄 [PUBDEV-5335] - In Random Forest, added back the distribution and offset_column options for backward compatibility. Note that these options are deprecated and will be ignored if used. [PUBDEV-5339] - MOJO export to a file now works correctly. 🛠 [PUBDEV-5343] - Fixed an NPE that occurred when checking if a request is Xhr.

    New Feature

    👍 [PUBDEV-5008] - Added support for ordinal regression in GLM. This is specified using the family option. [PUBDEV-5274] - Added the exclude_algos option to AutoML in Flow. [PUBDEV-5308] - Added a Leave-One-Out Target Encoding option to the R API. This can help improve supervised learning results when there are categorical predictors with high cardinality. Note that a similar function for Python will be available at a later date. 🔊 [PUBDEV-5324] - POJO now logs error messages for all incorrect data types and includes default values rather than NULL when a data type is unexpected.

    Improvement

    🚚 [PUBDEV-5344] - Moved AutoML to the top of the Model menu in Flow.

    📄 Docs

    [PUBDEV-5306] - In the GLM chapter, added Ordinal to the list of family options. Also added Ologit, Oprobit, and Ologlog to the list of link options, which can be used with the Ordinal family.
