I may risk sounding pretty dramatic... but multisig is probably by FAR the most meaningful addition to Monero's features on the docket. Hopefully it can be a point release, but of course let's let the devs get it right. Patience.

As is widely but probably not universally known, our multisig will not require a hard fork and will not be distinguishable from regular (single signer) transactions on the blockchain.
I don't know what that means in terms of when it gets released. More about what it doesn't mean (doesn't have to wait for a hard fork release nor activation)
