He's asked us to support a new signature type (BLS) which allows for a more compact multisig. It's not strictly needed for VSC, IMO, although it would be helpful for VSC when creating multisigs for managing Hive assets (specifically Hive and HBD) and they definitely want it.
We haven't worked on it yet, but making changes to signature handling is the last big thing on the list of things we're hoping to add to hived in this release.
I've done work on how I want to change the signing algorithm in general, but I haven't looked much into the BLS aspect yet. The main issue is the other guy I want to work on this issue with has been tied up with another high priority task, but he should be free soon, then we'll attack the issue together.
But I'm not 100% sure yet we'll be be able to get any of the changes to signature handling into this hardfork. If not, that means we'll need to make the next hardfork sooner, so I'm still vaguely hopeful we can get it in.
