2.4.0 (July 19th, 2024)(Please use 2.4.0.1)

Please use 2.4.0.1 first

This version is an important version which support many new features.

The most mainly feature is Nacos support maintainer to initialize the admin user nacos password instead of using default password to improve the default security for deploy nacos clusters.

One more thing is default disabled derby ops API to prevent false alarms regarding corresponding risks for users without authentication enabled when deploying in standalone mode. If maintainers want use this API to maintain and query data in derby, maintainers can use nacos.config.derby.ops.enabled=true to open this API.

And other mainly features are support TLS Grpc communication between Nacos cluster nodes as an optional feature to improve Nacos security, which means nacos not only support TLS communication between client and server; What's more, Nacos start to support user extend Selector before callback Subscriber for naming module, not only can select instance of services by healthy and clusters. And Nacos client support callback service diffs by new event to reduce Subscriber cache and compare logics.

Third mainly features are support some configs usages in Nacos console and support more enhancement usage for plugins, such as support add all metadata to prometheus sd protocol and support aliyun ram v4 signature.

In addition to substantial feature updates, this version also fixes some bugs from previous versions and upgrades certain dependencies with security vulnerabilities.
