I have a Zino drone one of the first series and always kept it updated. Today I dowloaded latest firmware Zino_firmware_20210201 to find out that the files are exactly the same of Zino_firmware_0622 issued last June 2020.
It also happened with a couple of other time with other releases.
Is there any explanation? What should I do load anyway the latest release even if it is the same already loaded?
Thank you

This happens a lot and usually only one or two things have actually changed. In the February update they changed the Gimbal Firmware from V3.0.2.8 to V3.0.2.13
