Sandfly v5.1.1 release.
IMPORTANT NOTE: Sandfly strongly recommends you purge all results ("Delete All" button on results pages) before upgrading to this release. This release fixes problems with past expired results not being fully deleted in the database, and the database upgrade scripts for this release may take a significant amount of time to run during server startup if result data hasn't been fully purged recently.
Please contact Sandfly Support if you have any questions before beginning the upgrade.
