   Thanks. @AlexanderSaydakov
    I found the issues you mentioned in the release notes of 0.14.1. 
   To confirm:
   1. the related bug about quantiles you mentioned above should be:  [#7320](https://github.com/apache/incubator-druid/pull/7320) or [0.13.1 Apr 2, 2019: Fix Direct DoublesUnion Quantiles Bug](https://github.com/apache/incubator-datasketches-java/releases/tag/sketches-core-0.13.1)
   2. and the newly introduced bug about theta sketch is: [#7607](https://github.com/apache/incubator-druid/issues/7607).
   
   We do use theta sketch, and I think the bug #7607 has been resoved in 0.14.2 ?
   [0.14.2-incubating release notes #7628](https://github.com/apache/incubator-druid/issues/7628)
   Bug Fixes
   #7607 thetaSketch(with sketches-core-0.13.1) in groupBy always return value no more than 16384
   #6483 Exception during sketch aggregations while using Result level cache
   #7621 NPE when both populateResultLevelCache and grandTotal are set
   
   So, is there other bugfixes for theta sketch to be released in 0.16.0?
   Should I upgrade to 0.14.2+, or cherrypick the datasketch module to build myself?
