Firmware request for MC60ECB

Good morning,
Sorry, new to this forum.
Is there a link to check regularly when firmware updates are available for Quectel modules ?
I am just starting on the MC60ECB, have GNS issues and errors.
The ATI command returned
Revision: MC60ECBR01A03
I would like to know if it is the latest firmware.

Yes this is currently the latest firmware, with i to error may be not following the steps on the AT instruction manual
