Resolved in this update

  • Some REST query responses where truncated. This occurred for datafiles with non-standard characters in column names and in delimiters of delimiter-separated values. The datafiles were truncated to just the first datafiles that didn't exhibit the behavior. The offending datafile and other following datafiles were not returned. This error was fixed so that non-standard characters do not affect the return result in any way. Original issue reported under jira ticket: DATAPREP-764.
  • There is improved Delete messaging to warn that an action cannot be undone. Original issue reported under jira ticket: DATAPREP-1490.
  • Logging has been added to capture successful password changes including timestamps. Original issue reported under jira ticket: DATAPREP-543.
  • An APF ticket can now be used to fetch the associated Run. Original issue reported under jira ticket: DATAPREP-603.
