Can I ask about the change of not keeping record of deleted files after 6 months by default. Does that mean if I sync two directories constantly so that if syncthing sees one of them has a file deleted, it will delete the file on the other too, if I copy back that same file into the synced folder, after 6 months pass Syncthing would sync that file again? Or what else does this mean?

Currently I am just using this to have an easy transfer between two computers, I keep moving out files that have been transferred from both folders, so I would think this has no effect on how I use it?

I would also assume most people interested in SteamDecks don’t care too much about its performance. As long as it plays older titles well enough or newer games that are not cutting edge in game engines it is fine.
