Sentinel v1.6.0 Release Notes

Release Date: 2019-04-25 // about 5 years ago

  • 💥 Breaking Changes

    🔨 In 1.6.0, we refactored the statistic and flow control algorithm of parameter flow control. The old mechanism (LRU map + sliding window for the parameter) has been replaced by an algorithm like token bucket. Now parameter flow rule supports setting statistic interval (intervalSec), burst count (burst), traffic shaping mode (controlBehavior, currently supports default mode and throttling mode).

    🔨 We've refactored and improved fallback support for @SentinelResource annotation to make it more understandable and common. See the document for more information.

    Since 1.6.0, all API gateway adapter will be based on the sentinel-api-gateway-adapter-common module. There are some changes for Sentinel Zuul Adapter. In previous versions, the adapter will mark all serviceId and API path as resources. Since 1.6.0, the adapter will regard all route ID (aka. proxy) and customized API groups (defined in API gateway common module) as resources.
