CB released for 1.8:

Thanks for the heads up, appreciated.

I built a copy of Spigot 1.8 and gave the latest build of HSP 2.0 a test run with it. All the basics seem to checkout fine. There is a possibility of issues with integrations (WorldEdit/WorldGuard, Multiverse, Dynmap, etc) but I couldn't get WE/WG running yet and I haven't tried all the others. They may work fine, so I'll let people report issues as they test them.

Leaving this open for a few days to prevent duplicate issues. If anyone does find any specific HSP bugs with Spigot 1.8, feel free to open a new ticket for it.

There is compatibility issue with WG 6 beta:

[HomeSpawnPlus] Error trying to resolve WorldGuard spawn (this message will only print once):
Found interface com.sk89q.worldguard.protection.ApplicableRegionSet, but class was expected

I've confirmed WG 6 compatibility on Spigot 1.8 servers. Closing issue.
