📣 Summary

v10.0.0 is the new stable mainnet release of the mezod chain client software.

This release prepares the ground for the upcoming revamp of the underlying EVM layer that will move the Mezo chain to parity with the EVM Osaka fork.

⚠️ This release incurs a mandatory upgrade of all Mezo Mainnet nodes that must occur on block 8773000 (ETA Thursday, May 7th, around noon UTC). Upgrading the node before the mentioned block will cause a failure.
