This version mainly introduces the configuration gray history record feature and refactors and optimizes the configuration gray management to enable users to manage configuration releases and gray configurations more efficiently. It is important to note that this update may lead to certain changes in the database table structure used by Nacos, and the first startup after the upgrade may take some time for automatic data migration (this situation only applies to clusters that have used the beta gray feature in older versions).

In addition to the above features, this version also includes significant optimizations and bug fixes for several other functions, including but not limited to the following:

• Unified client addressing logic and provision of custom extension interfaces.
• The client will automatically refresh the token when encountering a no-permission status during requests, without waiting for the token to expire.

Please see the details of the changes below:
