Stock Jumper T8SG, V2, V2 Plus firmware

Do I need this? I downloaded the 8-23-19 Dfu I saw yesterday. Haven't burned it on yet. Then there is the Nightly Build file. Now I see this. I'm still new to this and seems it's a continuous upgrading process. Sorta the Dfu dujour . Please advise. Thanks. I can't apologize for my ignorance, I can only try to educate it away. I just want something that works. My Bayang whoops do great but I have yet to find a .ini for my Bugs 3 or Mini that will fly. They bind up, arm, take off but then go crazy. They fly great with the OEM tx. <scratching head>
