It's Official: The Stacks 2.1 Upgrade is Approved
Published by Stacks Foundation Team on December 16, 2022
Votes are in and it’s official: the Stacks 2.1 upgrade is approved! This upgrade includes new functions and improvements that make the Stacks Bitcoin layer more powerful and more useful. Below, we've recapped what you can expect in terms of the remaining rollout process, a breakdown of the voting results, and resources to help you stay up to date.

What to expect now

Currently (as of 3pm ET on December 16th), the code for 2.1 is in the process of being merged. Shortly after, Release Candidate binaries will be made available (likely within the next few hours). As miners start to adopt, the upgrade will go live on the network. Miners normally upgrade their software within a few days, but sometimes it can take longer.

January 17th: Pox-2 contract activates
Last but not least, the new rules related to Stacking go live on January 17th. This specific part of activation was placed approximately one month out from Stacks 2.1 going live to provide integration partners time update their Stacking products.

What do I do next?
Many, probably most, users won't have to do anything! Many exchange or custodial solutions are not planning to make users do anything to remain Stacking, but you should look for communications from them directly. If you're Stacking solo or in a community pool, your Stacks will come unlocked in one of the next cycles as the switch to the new PoX contract gets closer. You'll then be able to re-Stack. Talk to your pool provider of choice for specific instructions and timing.

If you're a miner, developer, builder, or other integration partner, you may still have some work ahead of you. Your options and resources are outlined on our helpdesk here and you can get in touch if you get stuck.
