Nebulas version 1.0.5 launched on the test network on June 15, 2018, and after three days of stable testing, was released to the Nebulas main network on June 18, 2018.

1.0.5 has been updated with the following:

Provide Blockchain.getAccountState function to help developers get the balance and Nonce information of a specific address.

Blockchain.getPreBlockHash and Blockchain.getPreBlockSeed functions are provided to help developers obtain the hash value and seed value of a previous block.

New Uint library, including different ranges of Uint types, helps developers to do overflow checking to avoid loopholes.

The Crypto library has been added to provide encryption and decryption functions. Permission checks within the contract will become more traversal.

With the release of version 1.0.5, the capability of smart contracts on the Nebulas chain has been greatly improved. We will go further in the 1.1.0 release to provide the ability to call between contracts to help people more easily apply smart contracts to a wider range of business scenarios.
