📣 Summary

v11.0.0 is the new stable mainnet release of the mezod chain client software.

This release upgrades EVM compatibility up to the Osaka fork. Please refer to the docs/evm-compatibility.md document for more details regarding how specific EIPs are supported on Mezo.

⚠️ This release incurs a mandatory upgrade of all Mezo Mainnet nodes that must occur on block 9275000 (ETA Thursday, May 28th, around noon UTC). Upgrading the node before the mentioned block will cause a failure.
