v0.6.2 (Pacific)

This release is a major upgrade from 0.5.x, and the code name for this release is Pacific. It contains the incompatible change in the logic of state transition, and will be activated from block height 432001 on mainnet (but 1 on testnet). In addition to some bug fixes, this release majorly contains the following changes:

• Fix the double gas fee on contract deployment and execution;
• Add new RPC APIs to query and subscribe raw blocks;
• Avoid signing asynchronous contract read request;
• Improve BFT consensus pre-commit state handling;
• Migrate project from go dep to go mod;
• Use golang 1.12.5 compiler by default (but still compatible with ≥ 1.11.5);
• Remove native voting protocol from the codebase.

v0.6.1

Update sanity check for API range queries (#1203)

v0.5.2

This is a minor release, which only involves ioctl changes:

• Executing contract view functions out of the block production cycle;
• Supporting overwrite semantics for account createadd;
• Avoiding password check when deleting an account locally.

v0.5.1

This is a minor release without breaking changes. In this release, we majorly:

• Fix account deletion and print action timestamp in ioctl;
• Make test account will not be merged into genesis by default;
• Improve the election lock granularity to prevent holding block process.

v0.5.0 (MainNet Alpha)

This is the official release for IoTeX blockchain mainnet alpha. In this release, we baked the blockchain which is consisted of the following components:

• Networking layer enables the peer-to-peer communication between IoTex nodes

• Blockchain APIs (through GRPC) allows applications and users to interact with blockchain.

• Ioctl allows users to interact with blockchain in console.

• Consensus runs Roll-DPoS algorithm to select the active consensus delegates among a pool of delegates (who are elected via staking and voting on Ethereum).

• Account protocol processes native IOTX token transfer.

• Ethereum virtual machine (EVM) with smart contracts written in Solidity enables developers to seamlessly port existing DApps here.
