9.0.20-0rc3 (api:genl2/proto:86-115/transport:14)
--------
* fix regression related to the quorum feature,
introduced by code deduplication; regression never released,
happened during this .20 development/release cycle
* completing aspects of "allow-remote-read=no" behavior
* build: add spatch-as-a-service
Please help testing this pre-release. If nothing serious is found
we will have a final release on October 10.
