fixcrypt wants the release of mainnet to have a baseline of changed features.  Some delays happened in our timeline and we may need to push it to mid/end of FEB just to be sure.  Fix is adding a lot recently to the core and wallet to get things ready for a really good core for mainnet. 

It's much better to delay a bit and get a stable core at the beginning than to rush out some funky code too early and got to be trying to bandage everything for the next year.

Fix has recently changed address handling so we can have features like offline transaction signing for our card/hardware system and also made changes to the wallet that allow for easy switching from mainnet wallet to testnet wallet without leaving the wallet itself.
