# v1.13.0 Release Note | ||
|
||
## Summary | ||
**v1.13.0 has a hardfork, which will be activated at block height 28,516,681 | ||
(ETA is around 02/19/2024 00:58am UTC) on IoTeX mainnet.** | ||
|
||
All nodes **must** upgrade to this release, otherwise the node runs the risk of | ||
not being able to sync with the IoTeX blockchain after other nodes have upgraded. | ||
|
||
**Note:** | ||
There's no change to the mainnet config.yaml and genesis.yaml. You only need to | ||
restart your node with the new v1.13.0 image. | ||
|
||
v1.13.0 marks a substantial advancement by upgrading IoTeX network's EVM to the | ||
latest Shanghai version. This upgrade brings in the new opcodes and improvements | ||
in Shanghai EVM, reducing gas cost with enhanced efficiency and reliability of | ||
smart contract execution, ultimately leading to a smoother and more cost-effective | ||
experience on the IoTeX network. | ||
|
||
We are also excited to announce that v1.13.0 has enabled deterministic deployment | ||
functionality on the IoTeX network! This feature would deploy a proxy contract | ||
at a fixed address (same for all blockchains), and then it can be used to deploy | ||
any contract to a deterministic address using CREATE2. This ensures that any | ||
contract could be deployed consistently across different blockchain platforms to | ||
the same address, eliminates possible variations, and greatly enhance the | ||
predictability and reliability of smart contract deployment processes, providing | ||
developers with greater confidence in their deployments and facilitating seamless | ||
integration with other systems and protocols. | ||
|
||
## Other Improvements | ||
v1.13.0 release also comes with a couple of improvements: | ||
1. Supported javascript tracing for web3 api `debug_traceCall` | ||
2. `ioctl` commandline tool added more w3bstream project commands, and set | ||
default endpoint to IoTeX mainnet | ||
3. Add operator address into node's metrics reporting | ||
4. Updated gas station logic to give a dynamic gas price suggestion | ||
5. Increase max code deployment size to 48kB, same as Ethereum's limit | ||
|
||
## Upgrade Priority | ||
v1.13.0 comes with a hardfork, so all nodes **must** upgrade in order to keep | ||
syncing with the IoTeX blockchain | ||
|
||
| Node type | Action | | ||
| ---------- | ------------ | | ||
| Delegate | Must upgrade | | ||
| Fullnode | Must upgrade | | ||
