HEDA Release 1.66 is scheduled to go to Sandbox orgs this evening (Dec. 5). Full release notes can be found here, https://github.com/SalesforceFoundation/HEDAP/releases/tag/rel%2F1.66

In this release we've modified a small number of SOQL query filters and ORDER BY statements to prepare HEDA for future compatibility with Salesforce Shield Platform Encryption. You will see no impact to your org as a result of this update.

Please Note: Due to the upcoming holidays this release, and the subsequent release to Production orgs next week, will be the last update for the 2018 calendar year. The next release (sandbox) is slated for January 8, 2019. Thank you!
