Note that voting for the RC-2 release has been cancelled due to the need for minor corrections based on community feedback. Sorry for the inconvenience.

RC-3 replaces RC-2 with the following minor changes:
* Ensure product naming is consistently 'Apache MADlib (incubating)'
* Git revision tag changed to rc/1.11-rc3

This will be the 5th release for Apache MADlib (incubating).

The main goals of this release are:
* new module (PageRank for graph analytics with grouping support included)
* improvements to existing modules (add grouping support to Single Source Shortest Path, reduce memory footprint of DT and RF, include NULL features in training DT, add support for array and svec output for Pivot module, utility to unnest 2-D arrays into rows of 1-D arrays)
* platform updates (GPDB 5)
* updates for Apache Top Level Project readiness and build process on Apache infrastructure
* bug fixes
* doc improvements
