What’s New in the Latest Nacos Pre‑Release: Features, Enhancements, and Bug Fixes

This version is a major release, containing significant changes, so we first publish this pre‑release test version.

Added support for configuration change hook plugins and control plugin functions, allowing users to extend pre‑check configuration reformatting, audit changes, capacity limits, brittleness, and notification changes.

Refactored data source plugins and module loader, making plugins easier to support more data sources and allowing some users to enable a single feature to save more memory.
