## Release Notes <a href="#release-notes" id="release-notes"></a>

Klaytn v1.11.0 contains a hardfork upgrade that results in backward-incompatible changes. All Baobab nodes have to be upgraded to v1.11.0 or higher before the target block number. The hardfork implements the features equivalent to Ethereum Shanghai hardfork. The hardfork block number for Cypress mainnet will be scheduled in the next version.

The hardfork schedule is as follows:

**Baobab Testnet**

* Block number: 131608000 (estimated time: 28 Aug, 10:30 AM UTC+9)
* Hardfork contents: Shanghai hardfork

### Hardfork features

* Adjusted gas cost of the COINBASE opcode according to [EIP-3651](https://eips.ethereum.org/EIPS/eip-3651) ([#1883](https://github.com/klaytn/klaytn/pull/1883))
