Iptv simple client advice

Good evening, I have an odroid c2 and an odroid n2, installed coreelec stable version 9.2, I heard in this forum about this addon iptv simple client versions that I can not find, I use version 3.8.7 but I do not think I can use higher versions to find them, if so how can I update the addon? is it necessary or am I a beta version and should I expect an official version that is not detected on coreelec’s addon update? Thanks.

IPTV Simple Client is at 3.8.7 for Leia. Last time (a few days ago) that I checked, it was the newest version available. The 4.x.x version is for Kodi Matrix, and is incompatible with Kodi Leia.
