Bukkit has decided to close up shop after 3 and a half years of dedicated work on the project. What this means for Cauldron is unknown currently. We will have to wait and see what Spigot does and talk amongst ourselves. Don't worry though, Cauldron shouldn't be going anywhere.
Here is the
post from Bukkit if you haven't read it yet.
Edit:
@md_5
tweeted that Spigot would be updating to 1.8. What that entails is to be figured out but it means that there are solutions in the works already. We've discussed a lot of other things in IRC as well. It's sad, but we should be able to come back from it given time.
Edit2:
In a weird turn of events, Mojang has announced that they owned Bukkit all along unbeknownst to anyone involved. They have stepped in and Dinnerbone will be updating Bukkit to 1.8 right away to keep it alive.
