We're testing next year's mainnet fork (MRL1, MRL4, block time change) in the next ~5 hours, hold thumbs that it doesn't explode into a million glittery pieces:)

If you want to participate you can run a testnet node, either from the 0.8.8.6 binaries from the site (to see how badly it breaks) or compiled from master (to see if you transition cleanly to the new fork). You probably won't have enough time to sync up from scratch, though.

I'll update this thread after the fork!
