Hello,
We have released Stacks version 2.4.0.0.0, available here: https://github.com/stacks-network/stacks-blockchain/releases/tag/2.4.0.0.0.
Forum Post: https://forum.stacks.org/t/stacks-2-4-is-here-stacking-to-be-re-enabled
**This is a required upgrade**
This release is the second hard fork accepted in [SIP-022](https://github.com/stacksgov/sips/blob/main/sips/sip-022/sip-022-emergency-pox-fix.md), which will re-enable PoX on the Stacks blockchain.
- - Activation is estimated for May 26th, 2024 around 2200 UTC, or Bitcoin block 791,551.
- - Stacking will be re-enabled for all users once activation height is reached (Bitcoin block 791,551).
This release is compatible with chainstate directories from 2.1.0.0.x and 2.3.0.0.x
However, failing to upgrade prior to Bitcoin block 791,551 will require a genesis sync.
Changelog:
## [2.4.0.0.0]
This is a **consensus-breaking** release to revert consensus to PoX, and is the second fork proposed in SIP-022.
- - [SIP-022](https://github.com/stacksgov/sips/blob/main/sips/sip-022/sip-022-emergency-pox-fix.md)
- - [SIP-024](https://github.com/stacksgov/sips/blob/main/sips/sip-024/sip-024-least-supertype-fix.md)
### Fixed
- - PoX is re-enabled and stacking resumes starting at Bitcoin block `791551`
- - Peer network id is updated to `0x18000009`

The previous message incorrectly listed "May 26th, 2024" as the estimated activation date.
This is incorrect, and should have been: "May 26th, 2023"
Apologies for any confusion this may have caused
