What’s New in Nacos 2.1.1? Explore Batch Register and Trace Event Features

2.1.1 Version Features

The recent release of Nacos 2.1.1 adds beta functionalities like batch register service and service trace events, addressing stability issues and extending the core solution introduced in Nacos 2.0.

Register Service: batchRegister

Nacos‑Sync, a tool for migrating services from Eureka, Consul and other registries to Nacos, has been updated for Nacos 2.0. Due to changes in the new version, a single client can register only one instance per server, but Nacos‑Sync can proxy multiple instances, facilitating scenarios such as gateways, proxies, and Dubbo3. The batch register feature is available for beta testing in version 2.1.1.

Service Trace Event

Alibaba Cloud supports the community with open‑source contributions. The MSE team, together with community members, has added a trace event capability that allows publish‑subscribe style monitoring, enabling customized SPI plugins for testing.

Note: Both features are in beta and their APIs may differ from the final release.
