I sent the following to user@ last week and received no reply.  Is there another more active venue for communication about the Avro project (e.g. IRC, Gitter, Slack, etc.)?

I’m investigating an issue that we’ve found in ADAM

https://github.com/bigdatagenomics/adam/issues/2058 <https://github.com/bigdatagenomics/adam/issues/2058>

also reported against Apache Spark at

https://issues.apache.org/jira/browse/SPARK-25588 <https://issues.apache.org/jira/browse/SPARK-25588>

Has the Avro schema compatibility determination changed rules between Avro versions 1.8.1 and 1.8.2?
