Full Changelog: v2.0.0...v2.0.1

v2.0.0

Summary

v2.0.0 has a hardfork, which will be activated at block height 31,174,201 (ETA is around 07/22/2024 00:05:55 AM 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 v2.0.0 image.

We are excited to unveil IoTeX Blockchain v2.0.0, a milestone in our journey towards a more scalable, secure, and user-centric blockchain ecosystem. This release introduces impactful features designed to elevate user experience and expand the capabilities of our staking eco-system, and includes enhancements aimed at improving the security and robustness of the blockchain system.

Users and developers are encouraged to review the updated documentation and migration guides ahead of the release to fully leverage these new features. We are excited to continue empowering decentralized infra for DePIN globally with the new IoTeX Blockchain v2.0.0 release.

Key Features and Enhancements

1. New NFT staking contract: introducing a new NFT staking contract that offers users enhanced flexibility and reduced constraints when staking their tokens
2. Migrate native staking bucket to NFT staking: users with native staking buckets can now seamlessly migrate to NFT-based staking, enjoying the benefits and flexibility provided by NFT-based staking
3. Delegate ownership transfer: delegates now have the option to transfer their ownership to newcomer, providing a streamlined process for management changes
4. Enhanced transaction handling: transactions sent in web3js API/format are now wrapped in a general container format, which improves accuracy of execution and compatibility across various tools and frameworks

Bug Fix and Performance Improvements:

1. Purge failed transactions: failed transactions are automatically purged from the action pool, ensuring they do not hinder block production. This enhancement optimizes network efficacy, reliability, and throughput.
2. Error handling in EVM module: handles missing transaction logs on contract's SelfDestruct() and managing unrecoverable errors effectively, enhancing robustness and stability of the system by ensuring that critical errors are properly taken care of

v1.14.1

Summary

v1.14.1 is the first maintenance release after the latest release v1.14.0. It comes with enhancements across various components such as blockdao, staking, API. Also, ioctl commandline tool has a fresh upgrade that supports two new powerful functions: ioID and w3bstream. The ioID function enables seamless integration and management of decentralized identities on the IoTeX blockchain. The w3bstream functions allows for efficient management of w3bstream project on the chain, from project creation, device registration, to message operation and prover management.

Bug Fix and Performance Improvements:

1. bumped go version to 1.21
2. Resolved an issue where the blockdao process could become unresponsive while checking the indexer. This fix ensures that the node process can receive the break signal and exit if needed.
3. Fixed an issue where the response ID type in the JSON-RPC API did not match the request type. This ensures consistency and reliability in web3js API.
4. Enhanced the deserialization process when retrieving block receipts, resulting in faster access and improved overall performance of the blockdao component.
5. Fixed wrong cache for API readState at tip height, now the cache always returns most accurate and latest result.

New Features and Enhancements

1. Added endorsement details to the bucket fetch APIs, providing more comprehensive information for stakeholders and improving transparency within the staking process.
2. Implemented rate limiting for the WebSocket API to prevent abuse and ensure fair usage. This enhancement protects the network from potential overload and improves service stability.
3. Enabled the ToEthTx function for grantReward action, allowing it to be processed as an Ethereum-compatible transaction. This improvement facilitates interoperability and expands the utility of the IoTeX blockchain.
4. Added 2 new commands ioid and ws to ioctl commandline tool. Enables the ioID management and w3bstream project functions.

Upgrade Priority

v1.14.1 does not have a hardfork, but contains several bug fixes, performance improvements, and new feature enhancements. All delegate nodes and API nodes are recommended to upgrade to v1.14.1 in order to provide the best up-to-date service

v1.14.0

Summary

v1.14.0 has a hardfork, which will be activated at block height 29,275,561
(ETA is around 04/03/2024 00:52:05 AM 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 v1.14.0 image.

Version 1.14.0 has enabled two significant new features: IIP-24 Raise Block Gas
Limit to 50M and IIP-25 delegate endorsement.

With IIP-24, the block gas limit has now been raised to 50M, greatly enhancing
the processing capabilities of the IoTeX blockchain while ensuring its stability.
This enhancement allows the blockchain to achieve a maximum of 1000 TPS
(transactions per second), significantly speeding up transaction processing on
the blockchain, especially during times of network congestion.

The activation of IIP-25 introduces a novel governance model: it allows big
stakeholder to create a bucket for endorsing delegate. This would make delegate
management more flexible and encourage more enthusiastic projects to become IoTeX
delegates and actively participate in the IoTeX network operation, thereby
fostering the inclusivity of the IoTeX network and enhancing the diversity of the
ecosystem.

Other Improvements

v1.14.0 release also comes with a couple of improvements:

1. Improved performance for DB snapshot operation
2. Enabled web3js format for CandidateActivate and CandidateEndorsement
3. Make action pick order deterministic
4. Added more unit tests and end-to-end tests
