The primary feature in this release is that Magic now (correctly) handles timezones, and also correctly associates the correct timezone with dates not having timezone information, if a "Default timezone" is specified. The only exception to this is the SQLite data adapter for everything except the log and tasks, since SQLite doesn't store date-time objects as such, but in fact stores these as strings in UTC format, without the trailing Z or other timezone specifiers.
However, all in all, date-time objects are now handled much better and more consistently as a general rule of thumb.
