i still use bitcoin-qt 0.8.x
i was wondering if i MUST upgrade in the near future to be compatible with the rest of the network.

is their an end date when everyone needs to be using 0.9.x or will 0.8.x last me for a good while ?
i just prefer the layout of 0.8.x before anyone asks why i do not upgrade =)
and yeah i no it might be vulnerable to heartbleed but i do not use rpc which i believe would make me not vulnerable ?

thanks happy people!
