We are happy to announce that Klaytn v1.11.0 has been released. This upgrade emphasizes the implementation of State Pruning and Node Storage Sharing features. For more information, please follow this link.
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 (#1883)
- Added the PUSH0 opcode to EVM according to EIP-3855 (#1861)
- Adjusted gas cost related to initcode according to EIP-3860 (#1888)
- Fixed to allow a new contract account to be created by overwriting an EOA (#1904)
Cautions regarding the v1.11.0 upgrade
Klaytn uses the urfave/cli to implement the command line interface such as ken and homi. Starting from Klaytn version v1.11.0, we switched to urfave/cli v2 to support YAML configuration files. As a result, flags (ex. –datadir) must come before args (ex. <keyfile>) which is more POSIX-compliant. You may need to update your scripts as needed.
For example, the below commands will not work. You must be careful because the command lines below, which were working well, no longer run correctly without an error message.
$ ken account import --password --datadir
$ ken --datadir ~/data init ~/genesis.json
$ kcn attach klay.ipc --exec API
$ homi setup local --cn-num 1 --servicechain -o ./homi-outputThe below commands will work. Please update your scripts like this example.
$ ken account import --password <passwordfile> --datadir <datadir> <keyfile>
$ ken init --datadir ~/data ~/genesis.json
$ kcn attach --exec <statement> klay.ipc
$ homi setup --gen-type local --cn-num 1 --servicechain -o ./homi-outputImprovements
