* [CHD-3834] [Platform/Requirements] Cerb now provides a more useful error message when the required 'mysqli' PHP extension isn't enabled.  Previously, since 6.7.0, a blank white screen was being displayed with no additional information.  The installation guides cover installing the extension but they aren't always followed (e.g. there isn't an official FreeBSD guide).
* [CHD-3830] [Reports/Localization] When running reports, the worker's current timezone is now used at the database-level.  Previously, timestamps were being converted into the worker's timezone, but any relative functions in database queries (like DATE_FORMAT) were using the server's timezone.  This led to report data being shifted by the worker's timezone offset.
