HOC 188.8.131.52 and 184.108.40.206 (May 14 and May 21)
HOC 220.127.116.11 release was entirely internal improvements. The 18.104.22.168 release had additional internal work and a couple of bug fixes. Here's what you might notice.
Mapping an encrypted field in a form to a corresponding encrypted field in Salesforce was not 'sticking'. The mapping disappeared when you saved the form. This has been corrected.
When adding a new occurrence to an existing opportunity, and defining a new location for that occurrence, the location creation screen was requiring the user to submit a latitude and longitude for that location. This has been fixed.
