Spigot and BungeeCord have both been updated to support Minecraft versions 1.7 through 1.8. You may find their respective jars and build numbers on the Jenkins download pages.
Please note that these builds are brand new and as such there may be bugs. When reporting bugs, please sure to do so to the appropriate places, ensure that you are on the latest builds, and ensure that versions of all softwares have been included.
Thanks, ~ Spigot Team
