Kind of late... But happy Mid-Autumn Festival! Believe you all having had a wonderful time with family~

This weekend, we brought a new version, named Osmanthus Cake(桂花糕 in Chinese) to everyone!

In this version, we add several system contracts to help you better manage the system. One is called emergency braking. Once the emergency braking mode is activated, only the transactions sent by the admin account can be accepted by the chain. It can be used in some extreme conditions, such as the operators of the chain need to carry out some upgrades and maintenance without others to interfere.

Another is the version manager, which is prepared for the subsequent fork of CITA to solve the data compatibility problem.

We also add the quota price manager contract according to the feedback from customers and the market. Now, quota price can be set by the admin account in this version when building a public permissioned blockchain, check the document for more details.

Moreover, we put lots of efforts to improve CITA quality and stability in this month - more comprehensive testing under production environment and more detailed documentation.
