What is expected to end up on the Exchange as v1.2 is now present on my own site (link in topic). Of note is the use of my Integration Toolkit's latest Tag Custom Property support for arbitrary tag relationship indexing. Adding that added more QA for me to do, but y'all are welcome to poke at it. (It also has stabs at alarm config, dataset CSV support, and better type coercion for all tag properties.)
Examples and docs have been updated.
Feedback is welcome.
