I wonder, though, why that fork exists or why the improvements of the fork are not incorporated in the main version. Usually, a fork marks some fundamental differences or trade-offs between different development paths, but I don’t really see that here. Could someone explain? @Catfriend1? @AudriusButkevicius?
This question comes up every now and then (understandably), but the only topic I found with it is Syncthing & Syncthing Fork - I feel like I wrote a somewhat more comprehensive explanation at some point. Anyway, the reasons stated there are still valid and if you want more details, you can dig them out in the forum and github history.
