Klaytn v1.8.0 Released

Klaytn is thrilled to finally release Klaytn v.1.8.0 after five months since its last big update.

Klaytn v1.8.0 contains a protocol upgrade which results in backwards incompatible changes, like the Ethereum hard forks. All nodes would thus have to be upgraded to this version before the target block number.

The planned hard fork schedule is as follows:

Baobab Testnet (Baobab block number 86513895, planned date: March 24)

• EthTxType hard fork: #86513895
  (IstanbulEVM and LondonEVM hard fork already applied on Baobab)

Cypress Mainnet (Cypress block number 86816005, planned date: March 31)

• IstanbulEVM hard fork: #86816005
• LondonEVM hard fork: #86816005
• EthTxType hard fork: #86816005

Note: Istanbul EVM hard fork includes changes in the gas cost for the EVM opcode as well as in using the APIs. The existing contracts may not function as expected due to these changes, so please refer to the [Cautions on the Protocol Update] section of this article.

Improvements

1. Adjusted account manager unlock timing when a node starts
2. Allowed add/remove multiple validators in a single vote
3.  Enhanced the validation logic of governance voting AP
4. Unified mutexes in blockchain.go

Fixes

• Fixed a governance cache initializing bug
• Fixed klay_gasPrice API to return proper gas price values
• Fixed race condition issues triggered by transaction fields update
• Fixed call tracer panic caused by deep return object

The new version is going to affect Klaytn DApps currently in service.
