Backward compatibility: INCOMPATIBLE — exact PR head 1af9fb64d81c83ed843017b0b886b8a6afa41887 compared with current master 1bbb062442e96e3eb9c8b25f33799cbc7b67ce0a. The prior closure of [apache/druid#20110](https://github.com/apache/druid/pull/20110) established that zstd-jni 1.5.7-15 removes decoding for legacy pre-1.0 v0.4-v0.7 frames: 1.5.7-11 decoded 5,345,280 bytes, while 1.5.7-15 failed with Unknown frame descriptor. The upstream 1.5.7-15 to 1.5.7-16 comparison contains no restoration of the removed legacy decoder, so this exact 1.5.7-16 head retains the same user-visible Druid batch-ingestion regression. Closing as high effort: preserving legacy frame support requires an explicit product/migration decision, a legacy-enabled build, or a version cap; it cannot be safely handled by this dependency-only bump. No tracked Java production or test source changed; the PR changes only POM/license metadata. -- This is an automated message from the Apache Git Service.
