Full Changelog: 2.5.0...2.5.1

This version is a pre alpha version of 3.0.0. In this version, Nacos based on Nacos 3.0.0-ALPHA and support more features:

1. According to Vote Issue #12923, almost all participants agreed to upgrade the JDK and Spring Boot versions. So in ALPHA.2, upgrade spring boot to 3.4.1 and upgrade jdk version to 17.
2. Add a serial of ADMIN API for Nacos 3.0 to make maintainer and custom console can maintain and get Nacos' data.
3. Support beta feature distributed lock.
4. More addition beta feature fuzzy listen services and configurations.

There are also some important changes in ALPHA.2:

1. According to Vote Issue #12922, most of participants agreed to remove the supported for Nacos 1.x clients. However, a few of users are concerned that some less frequently used multilingual SDKs are still not compatible with gRPC access. Removing the client's API would make it impossible to use these SDKs. Therefore, the community has temporarily only blocked the 1.x and 2.x console API and admin API (they can still be enabled with a switch). The 1.x openAPI has not been blocked, and further discussion and observation within the community are needed to decide whether to remove it in the BETA or the official 3.0.0 release.
2. According to 3.0 planning, the Admin API, Console API and Inner API is need to authentication by default. In ALPHA version, the Console API has open default auth, so from ALPHA.2, the Admin API is authed by default, access Admin API should with admin user nacos.

Welcome community developers and users test and try out this version and report problem and suggest to Nacos.

Warning: 3.0.0-ALPHA.2 is a pre version, it's features and APIs might so some adjustment in future versions, please don't used in product environments.

Full Changelog: 3.0.0-alpha...3.0.0-alpha.2

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.
