Bug
📜 [PUBDEV-5724] - H2oApi.frameColumn in h2o-bindings.jar now correctly parses responses. 🚀 [PUBDEV-5751] - biz.k11i:xgboost-predictor:0.3.0 is now ported to the h2oai repo and released to Maven Central. This allows for easier deployment of H2O and Sparkling Water. [PUBDEV-5786] - In GLM, the coordinate descent solver is now only disabled for when family=multinomial. 📜 [PUBDEV-5792] - Fixed an issue that caused the H2O parser to hang when reading a Parquet file. 🛠 [PUBDEV-5803] - Fixed an issue that resulted in an AutoML "Unauthorized" Error when running through Enterprise Steam via R. [PUBDEV-5818] - Leaf Node assignment no longer produces the wrong paths for degenerated trees. 🚀 [PUBDEV-5823] - Updated the list of Python dependencies on the release download page and in the User Guide. 🛠 [PUBDEV-5826] - Fixed an issue that resulted in a mismatch between GLRM predict and GLRM MOJO predict. [PUBDEV-5844] - Launching H2O on a machine with greater than 2TB no longer results in an integer overflow error. 📜 [PUBDEV-5847] - The HTTP parser no longer reads fewer rows when the data is compressed. [PUBDEV-5851] - AstFillNA Rapids expression now returns H2O.unimp() on backward methods.
New Feature

[PUBDEV-5779] - In GBM, added a new staged_predict_proba function. [PUBDEV-5812] - MOJO output now includes terminal node IDs. [PUBDEV-5832] - GBM/DRF, the H2OTreeClass function now allows you to specify categorical levels.
Task
⚡️ [PUBDEV-5845] - Updated the XGBoost dependency to ai.h2o:xgboost-predictor:0.3.1.
Improvement
[PUBDEV-5837] - Terminal node IDs can now be retrieved in the predict_leaf_node_assignment function.
📄 Docs
👍 [PUBDEV-5836] - The User Guide now indicates that only Hive versions 2.2.0 or greater are supported for JDBC drivers.
