Emonevse Firmware update from 4.1.1

I am running firmware 4.1.1 on my emonevse. One with an ethernet card, not wifi. Seems like the mqtt for pilot is not updating, so I was wondering if there is a firmware update I can install on it? I tried to navigate the jungle of different options and choices but now I give up, and ask for help. Anyone has a link to the proper file I need to download, and upload to the emonevse?
