Developer console is showing security alerts on all of my cocos2d-x v2.x games with detail of using old libpng.
In cocos2d-x v2.2.6, I have found libpng two files png.h & pngconf.h with v1.2.46 and as resolution is suggested to use 1.2.56 latest version for this one.
I have submitted a build with these two updated files to see if that was the resolution. Will post if got SUCCESS.
Please if anyone have found other solution, then share.
