The banner at the top of the page said "update to Ledger Live 2.43.1", but when I actually went through with the update, it said that I updated to version 2.43.0.
I haven't updated to the latest version either. I am also still on v2.42.0. It seems that they migrated to a new repository, that's why there is no information about the changes made in the newest versions in the old GitHub repository. The new one is
here, but I can't find any release info. According to the
Ledger Live downloads page, the newest version is indeed 2.43.1. Not sure why you couldn't immediately jump to the latest one and the software upgraded to 2.43.0 first. I will take a look at it to see if the same thing happens to me when I decide to make the update.
