Release Notes

MADlib v1.19.0:


Release Date: 2022-March-09


NOTE: This release changes MADlib library location and updates UDF definitions.
To ensure this change is reflected in the database, pg_ctl (for Postgres) or gpstop (for Greenplum) has to be in the PATH at the time of madpack installation.
Views depending directly on madlib defined function(s) have to be dropped
before upgrading.

Improvements:
    - Graph: Improve WCC subtx count and catalog entry frequency (MADLIB-1492)
    - MLP: Set lambda value for minibatch

Bug fixes:
    - PMML: Rename builder.py to circumvent ignore scripts
    - DL: Fix object table schema error message
    - DL: Fix metrics error message
    - DL: Remove AOcontrol from load_top_k_accuracy fn
