They've changed antennas. The new antennas offer a significantly higher gain over the old antennas. This is a quote from Flying Giants hope it helps:

It has been stated that nobody knows what the gain difference is between the old and new antennas. Well it is right in the FCC document for AZP-R7014SB-24G permissive change from the old to new antennas page 7, section 3.3:

The old antennas have a gain of -5.35 dBi
New antennas have a gain of +2.10 dBi

A change of 7.45 dBi is not a slight improvement. It is a huge improvement in a link budget.
