Mina Mainnet Stable 4.0.0 Mesa Release

[amc-ie]

🎉The o1Labs team is proud to announce that the 4.0.0 Mesa Stable Release is now ready and available for Mainnet! 🎉

This release represents the final stage in the Mainnet manual upgrade process which concludes the execution of the upgrade mechanism for this network. This mina daemon release only applies if you are using the legacy stop slot version or are joining the network for the first time. If so, you will not be able to connect to the network without using this version. The mina daemon upgrade is not necessary for those having used the automode version for the upgrade.

If you run into any issues, please include Release: 4.0.0-mainnet-mesa in the name of any issues you create. Please report any issues you encounter here or join the discussion!

What’s Included in the Mesa Upgrade?

The Mesa Upgrade encompasses four Mina Improvement Proposals (MIPs) and one upgrade mechanism enhancement:

• Slot Reduction (MIP6): Reduces slot time to 90 seconds, increasing transaction throughput and improving the overall user and developer experience.
• Increase On-Chain State Size Limit (MIP7): Expands the number of on-chain state fields from 8 to 32, giving developers more flexibility.
• Event/Action Limit Increase (MIP8): Raises the current limits on events and actions, enabling more expressive applications and reducing the number of transactions end users need to approve.
• Account Update Limit Increase (MIP9): Raises the limit on account updates per zkApp transaction, allowing more complex logic to be executed within a single transaction.
• Hard Fork Automation: Introduces new automation infrastructure for conducting future hard forks, making the upgrade process simpler, less manual, and more efficient.
