There are still quite a few wallets running the old protocol version 10100 out there.
Everybody please update to the latest wallet version. It contains some important network improvement fixes.
Thanks for the update bro. I have a question if i continue using old wallet is any problem. Is a long story, short i can't download anything from internet for now!
It is possible that you end up in your own fork. It may work forever but it is not guaranteed: it depends on how the chain evolves.
Will update it when I'll be forced to use the coins, transfer them, until then I think I don't have any issue. Anyway I have saved my private keys previously.
