## Jan 11, 2021 update ##
There seems to be some beta issues around the checked_out value.
In J3: 0 = not checked out, in J4: NULL = not checked out.
The actual setting of the value is done by Joomla, not ABPro, but the values are still updating to 0, hence the current ABPro 4.0.5 seems to work in beta 6 but shows lots of tables in Global Checkin.
