Kapacitor release candidate builds?

Is there any way to download RC builds for Kapacitor? I see posts here for Telegraf rc builds (e.g. Telegraf v1.5.0-rc1), but munging the urls to follow a similar pattern for Kapacitor doesn’t yield anything.

@msherry If you go to the Influx downloads page and click on Kapacitor, you can see the rc url.
