Hello Apache MADlib Community,
This is the vote for Apache MADlib 1.19.0 Release (RC3). It provides the source
release tarball and convenience binaries.
The vote will run for at least 72 hours and will close on March 8th, 2022
@19:00 UTC (14:00 EST). A minimum of 3 binding +1 votes and more binding +1
than binding -1 are required to pass.
The main goals of this release are:
New features:
- DBSCAN: Fast parallel-optimized DBSCAN (MADLIB-1017, MADLIB-867)
- MLP: Add rmsprop and Adam optimization techniques (MADLIB-1434,
MADLIB-1435)
Improvements:
- Graph: Improve WCC subtx count and catalog entry frequency
- 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

- GLM-multinom: Use non-temp tables in GroupIterationController
Other:

param
- Jenkins: Add new dockerfile for PG11 (MADLIB-1469)
- Build: Use dynamic_library_path for module pathname

NOTE:
This release changes MADlib library location and updates UDF definitions. Views
depending directly on madlib defined function(s) have to be dropped before
upgrading. pg_ctl has to be in the environment PATH for the installation
process to correctly set the dynamic_library_path value.
