In regards to the recent hack this is what I remember seeing posted from the DEV
Hey everybody,
We've just published MangoCoinz v0.5.2 and it will be available to update in a few hours.
This is a security update, and updating from v0.5.1 will not result in coin loss.
A short time after the update is available, it will be the only version able to interact with the system.
Best regards, Srele from MangoCoinz.
Notice that he says "A short time after the update is available, it will be the only version able to interact with the system."
Meaning that when I explained about how you could earn heaps of MangoCoinz on the older app versions and then when choosing to you can update to the latest version and sync it up with no limit or a very high sync limit for 1 day since those coins were earn't on different kinds of settings.
I was told this is not possible by the DEV yet he has said in the latest release "A short time after the update is available, it will be the only version able to interact with the system"
I think we have a bit of a hiccup here.
this must have been from the api's used prior to the 0.5.2 because i can vouch that the apiv2 did not accept requests with a lower version than 0.5.2, a majority of the fixes in that release were bugs and issues i reported to the developers privately, i havent bothered to look at any of this in about 2 weeks but with the permission of the devs ill gladly take a look again if they would like
