Sentinel v1.5.0 Release Notes

Release Date: 2019-03-14 // about 5 years ago

  • 💥 Breaking Changes

    Since 1.5.0, the minimum JDK version has been updated to 1.7. JDK 1.6 is no longer supported.

    There are some changes in Node interface: the return type of xxxQps methods (e.g. passQps, blockQps) has been changed from long to double to be more accurate.

    👍 In 1.5.0 we added common occupy mechanism in LeapArray so that Sentinel can occupy future buckets of the sliding window to support "final pass for prioritized requests when QPS exceeds the threshold". The Sph.entryWithPriority(xxx) method will take effect now in local flow control mode.
