 3. Edit `$IOTEX_HOME/etc/config.yaml`, look for `externalHost` and `producerPrivKey`, uncomment the lines and fill in your external IP and private key. If you leave `producerPrivKey` empty, your node will be assgined with a random key.

 In step 4, you need to use the snapshot for TestNet: https://t.iotex.me/testnet-data-latest and https://t.iotex.me/testnet-data-with-idx-latest. If you need legacy delegate election data(poll.db) for TestNet, you can download it here: https://storage.googleapis.com/blockchain-golden/poll.testnet.tar.gz

+### v1.3.0 Release Note
+**Note that v1.3.0 has a hardfork, which will be activated at block height 12,289,321 (7/22/2021 ~2pm PDT) on IoTeX mainnet.**
+1. v1.3 has upgraded to latest EVM version so user can confidently deploy their
+DApps to IoTeX blockchain. This EVM upgrade supports the ChainID opcode to
+prevent relay attacks and enable cross-chain transparency, and has optimized gas
+costs of certain opcodes, especially privacy and zk computations. Click
+[here](https://github.com/iotexproject/iotex-bootstrap/blob/master/changelog/evm-istanbul.md)
+for details
+2. Optimized block sync strategy to make it more robust
+3. Fixed a bug that API query needs to wait a little while to return the latest
+committed block
+4. Fixed a bug that node stops working after network connectivity is lost. Now
+the node can detect the network loss/reconnect event, and automatically resume
+working after network connectivity is restored
