❗ This release is only to be used as part of the manual Devnet Upgrade ❗

---

This release is the first phase of the Devnet upgrade that specifies the stop slot in the codebase and formally begins the upgrade process. This is the first stage in a two part process; a subsequent Devnet release will then usher in the new era of Mesa functionality on our Devnet. The stop slot will take effect at 15:00 UTC on August 19th 2026, please upgrade your devnet nodes before this time!

If you would prefer an easier upgrade experience, we recommend that you use our new automode upgrade mechanism that allows for a hands free, seamless transition to the new era and only requires one upgrade.

For this release we have temporarily enabled node status tracking by default to help us track the successful progress towards the devnet upgrade. This behaviour can be turned off by starting the node using the --disable-node-status flag.

This Mesa upgrade release contains everything you need to automatically upgrade to the Mesa era on Devnet. The new approach will allow for much faster and seamless hard forks\upgrades for Mina in future and we are very excited to share it with you!

If you would prefer to handle the upgrade manually (i.e. in two parts), we recommend that you use our legacy stop slot build. This will require an additional upgrade after the Mesa Devnet netwokr starts; this will be made after the HF takes place.

For this release we have temporarily enabled node status tracking by default to help us track the successful progress towards the devnet upgrade. This behaviour can be turned off by starting the node using the --disable-node-status flag.

🚨This hotfix release is only for users running the Archive Node service.🚨

For Mina Daemon and Rosetta users, please refer to the 3.2.0 stable release.

---

This 3.2.1 hotfix releases for Mainnet fixes a very rare edge case on read operations that was caused by a race condition within Archive Node. No other Mina components are affected or changed by this fix. It is recommended to upgrade to this version to avoid the chance that this issue will be encountered at any stage in the future.

As always, if you run into any issues please include Release: 3.2.1 in the name of any issues you create. Please report any issues you encounter here or join the discussion
