The first version of the mainnet came out back in June. It gives users embedded management tools, such as KYC and makes sure that these tools are based on smart contracts, so that they are efficient and transparent.
The new version of the mainnet is available on VeChain’s GitHub site and it contains some new features and remedy to some of the bugs. The source code will now be able to deal with new blocks and events. It will also be able to customize a limit of gas for one block, reportedly.
