SQL Change Automation now uses version 4.1 of Microsoft.Data.SqlClient library. This version contains a breaking change - "Encrypt" parameter value is now set to "True" by default (instead of "False"). This might cause a need for you to reconfigure your SQL connection in some cases, as SQL Change Automation will now assume that "Encrypt" is "True" if it was not specified. This also applies to the New-DatabaseConnection cmdlet.
DacFx Parser version 16 has been added to SQL Change Automation.
