5.3.1
In 5.3.0, we've introduced a bug on Snowflake Loader that makes it not copy contexts and unstruct events to events table. We've fixed this problem in version 5.3.1. Thanks mgkeen for reporting this issue. Recovery instructions for missing data can be found in the Discourse post.
Also, in this version, we've started to use VARCHAR instead of CHAR with standard fields when creating events table on Databricks Loader (Github issue).
