v1.11.1

Summary

v1.11.1 is an important maintenance release, which fixes a bug in the system
staking contract. The issue was discovered in a pro-active manner, and
precautionary actions are taken to make sure that no actual harm/damage is done
to the system staking.

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 latest config.yaml and genesis.yaml. You only need to
restart the node with the new image.

Other Improvements

v1.11.1 release also comes with a couple of improvements:

1. Enforce height check for system staking indexer to increase error detection
   and handling robustness
2. Fix revert message in eth_call
3. Fix panic: concurrent write to websocket connection
4. Fix staking action ToEthTx() panic
5. ioctl] action transfer now supports 0x address format
6. Added a new ioctl ins register command for INS service

Upgrade Priority

v1.11.1 contains a mandatory bug fix, so all nodes must upgrade in order to
keep syncing with the IoTeX blockchain

v1.11.0

Summary

Version 1.11.0 includes a hardfork that will be activated on the IoTeX mainnet at block height 24,838,201 (ETA approximately 07/20/2023 11pm UTC). It is imperative that all nodes upgrade to this release. Failure to do so will result in the inability to sync with the IoTeX blockchain after the activation block.

Note:
Prior to restarting the node, you must upgrade to the latest config.yaml file. It contain new configurations required for v1.11.0 to function properly.

Instructions for configuring a node can be found here: https://github.com/iotexproject/iotex-bootstrap#join-mainnet

Breaking Changes

v1.11.0 enables 3 important features:

1. IIP-13 Represent Staking Buckets As Non-fungible Tokens
2. IIP-14 Account Abstraction
3. Enforce ChainID in transaction to prevent possible replay

IIP-13 Represent Staking Buckets As Non-fungible Tokens

IIP-13 supports native representation of staking buckets as Non-fungible Tokens
on the IoTeX blockchain, which opens opportunities for applications such as
Liquid Staking Derivatives (LSD), where these buckets can be traded or used as
collateral in other DeFi protocols. This in turn increases the overall staking
ratio and therefore enhances the degrees of security and decentralization of the
IoTeX blockchain.

IIP-14 Account Abstraction

IIP-14 Account abstraction is a ground-breaking proposal that aims to enhance
the IoTeX platform by abstracting various account operations and properties,
such as authentication, authorization, replay protection, gas payment, batching,
and atomicity. IIP-14, based on EIP-4337, makes IoTeX a more user-friendly and
secure platform, surpassing the limitations of externally owned accounts (EOAs).
For more information on the implementation details, please refer to ​our github
repo here

Enforce ChainID in transaction for enhanced transaction security

In v1.8 release, we added ChainID into transaction to distinguish transactions on
different networks. In this v1.11 release, the additional constraint is enforced
that each transaction must bear with it the correct ChainID (1 for mainnet, and 2
for testnet), and the default ChainID value 0 will be rejected. This would further
enhance the security of the IoTeX blockchain.

Other Improvements

v1.11 release also comes with a couple of small improvements:

1. Added an ioctl bc delegate command to retrieve the detailed info of a delegate
2. Added summary about the node status into console log output
3. Enabled message batch in API service to improving network data efficiency
4. Added an ioctl did service command
5. Added system action validation step in the block validation process

v1.10.1 Release Note

Summary

v1.10.1 is a maintenance release, with couple of improvements:

1. Added ChatGPT code review, leveraging the latest AI technology to safeguard
   the code quality.
2. Implemented 2 web3js API: debug_traceCall and debug_traceTransaction which
   further increased our chain's compatibility with the Ethereum ecosystem.
3. Limited batch size for web3 API request, to help rate-limit the API endpoint and
   protect against potential DDoS attack.

v1.10.0

Summary

v1.10.0 has a hardfork, which will be activated at block height 22,991,401 (ETA is around 04/04/2023 11pm UTC) on IoTeX mainnet.

All nodes must upgrade to this release, or otherwise the node won't be able to sync with the IoTeX blockchain after the activation block.

Also we'll use this release opportunity to disable the auto-upgrader, since the auto-upgrader is a fixed script that cannot adapt perfectly well to each release scenario, and has caused a couple of failed upgrades in the past.

In the past, if you use the one-line upgrader tool to run your IoTeX node, please continue to use it to do the v1.10.0 upgrade. This time the script will turn off the auto-upgrader (if it was turned on before). Run the script below just as before.

sudo bash # If your docker requires root privilege
bash <(curl -s https://raw.githubusercontent.com/iotexproject/iotex-bootstrap/master/scripts/setup_fullnode.sh)

If you use the very long docker run command (like below) to run your IoTeX node, don't worry about the auto-upgrader since it is not turned on. Continue to upgrade your node using the v1.10.0 image:

docker stop iotex
docker rm iotex
docker run -d --restart on-failure --name iotex \
        -p 4689:4689 \
        -p 8080:8080 \
        -v=$IOTEX_HOME/data:/var/data:rw \
        -v=$IOTEX_HOME/log:/var/log:rw \
        -v=$IOTEX_HOME/etc/config.yaml:/etc/iotex/config_override.yaml:ro \
        -v=$IOTEX_HOME/etc/genesis.yaml:/etc/iotex/genesis.yaml:ro \
        iotex/iotex-core:v1.10.0 \
        iotex-server \
        -config-path=/etc/iotex/config_override.yaml \
        -genesis-path=/etc/iotex/genesis.yaml

Breaking Changes

v1.10.0 enables 2 important features:

1. Claim reward via web3.js protocol
2. Node status monitoring by p2p messaging

Claim reward via web3.js protocol

Similar to how we enabled sending transfer and staking actions via web3.js protocol, in v1.10.0 claim reward is enabled as well. Delegates can now send claim reward action using Metamask.

Node status monitoring by p2p messaging

Currently, the IoTeX node is relying on a pre-defined HTTP port to collect the real-time running status, such as the software version and blockchain height. This means that delegate nodes need to open up that HTTP port which might be a security risk, especially for nodes running on clour service provider. It also requires delegate nodes to expose their public IP address, which is not preferred due to both security and privacy concerns, and creates additional maintenance burden to manually update the IP address in case it changes.

In v1.10.0, a new node status monitoring solution is implemented based on the existing p2p network. By exchanging messages about their running status using the p2p network, delegate nodes no longer have to publicize their IP address nor open that specific HTTP port. In addition, the external IP address of a node can now freely change (like being assigned a new IP address after reboot) without worrying about status reporting/collection.

Also in upcoming new releases, we'll introduce more advanced node status monitor functionalities. For instance, an automatic alert service where delegates can register a webhook and receive notification when the node is becoming offline or entering probation.

v1.9.2: [API] add batch size limit for jsonrpc (#3805)

Summary

v1.9.2 is a maintenance release, with the following fix:

1. Limit the maximum size of RPC response data to prevent node from running out
   of memory.

Upgrade Priority

If your node is running as gateway, it is recommended to upgrade to v1.9.2 to
better protect it from potential out-of-memory attack.

v1.9.1

Summary

v1.9.1 is a maintenance release, with 2 fixes:

1. Certain build config is accidently deleted, causing git version and commit_id
   being missed from the software binary. This is a quick fix to restore that info
   so delegate nodes can correctly report the binary version they are running.
2. ioctl node delegate command can correctly show all probated delegates now.

Upgrade Priority

All delegate nodes must upgrade in order to correctly report the binary version
they are running.

v1.9.0

Summary

v1.9.0 has a hardfork, which will be activated at block height 21,542,761 (ETA is around 01/11/2023 12am UTC) on IoTeX mainnet.

All nodes must upgrade to this release, or otherwise the node won't be able to sync with the IoTeX blockchain after the activation block.

v1.9.0 enables couple of important features:

1. Zero-nonce feature
2. EVM upgrade to London
3. Complete fix to the issue patched by v1.8.4

Breaking Changes

Zero-nonce for new account

With this new feature, a newly created account will have 0 as its initial nonce. For historic reason, our mainnet is launched with that initial nonce value equal to 1, which is different from Ethereum's convention that the initial nonce starts from 0. Starting from v1.9.0, this behavior will converge to Ethereum's convention, further enhancing our chain's compatibility with Ethereum eco-system. In particular, the Gnosis Safe protocol (which hinges on this zero-nonce property) will be able to successfully integrate with the IoTeX blockchain after the v1.9.0 launch.

EVM upgrade to London

With v1.9.0, the EVM has been upgraded to London (and including Berlin), which enables many important EIPs. For example, EIP-2565 lowers ModExp gas cost and EIP-2930 provides an optional access list (a list of addresses and storage keys) to reduce the gas cost when accessing these addresses and keys during contract execution. Here's a complete list of EIPs enabled in London:

1. EIP-1559: Fee market change for ETH 1.0 chain
2. EIP-3198: BASEFEE opcode
3. EIP-3529: Reduction in refunds
4. EIP-3541: Reject new contract code starting with the 0xEF byte
5. EIP-3554: Difficulty Bomb Delay to December 2021

and EIPs enabled in Berlin:

1. EIP-2565: ModExp Gas Cost
2. EIP-2718: Typed Transaction Envelope
3. EIP-2929: Gas cost increases for state access opcodes
4. EIP-2930: Optional access lists

Other Features and Improvements

Complete fix of issue patched by v1.8.4

v1.9.0 has provided a complete fix to the issue patched by v1.8.4. After the v1.9.0 upgrade, the manual patch will no longer be needed, and we'll deprecate the patch in upcoming releases.

Other Improvements

Couple of small improvements are added into v1.9.0, including:

1. Disable http admin port by default
2. DB will panic when no space left -- better error visibility
3. Fixed slow context in workingset for faster block processing
4. Fixed use of weak random number generator
5. Fixed variadic interface bug
6. Fixed file permission
7. Add ReadHeaderTimeout for http connection
