The latest firmware for the Sony a7 III is now version 2.00 released on October 10, 2018.

Firmware version 2.00 adds support for the new FE 400mm F2.8 GM lens as well as the new FE 24mm F1.4 GM lens. And if you are using the LA-EA3 mount adaptor then you might be happy to know that Zone, Expand Flexible Spot and Lock-on AF focus areas are now supported.

Unfortunately this firmware version has also introduced a check for third party batteries like Wasabi. If a third party battery is detected you’ll get a warning message that you have to OK, you then lose the percentage indicator next to the battery. It appears Sony is going to war with third party battery suppliers.
