The official hasn't released a new official firmware for a long time. However, I found on the forum that there are versions 5.7.2 and 5.7.3. Our agent also provided 5.6.255. But the official's latest official version is only 5.6.251. So, can 5.7.3 be used? What has it updated? Because I heard that some people playing Apex found that 5.7.3 seems to be better.
