I think that Bittrex said it will delist SFR on September 23th, but they didn't (though they delisted some coins), which means that they are still giving a chance for SFR. Here is their latest statement:

Saffron is among the coins, which will be removed, but they are not saying that they will disable the market for sure.

Yes, looks like they may still delist it but are giving a little longer to see if trading activity picks up or the dev gets in touch.

where is the source code for the 2.6.2 wallet? all i could find was for 1.4.2
