Just wanted to give an update:
Today we will be releasing a wallet update which will include (anon) EM invoicing + receipt features & will also include minor bug fixes.
The (anon) EM invoicing / receipt feature will be the first phase of our point-of-sale system which we are actively developing (see old ann for more details). Greater detail will be provided soon.
The wallet with (anon) EM invoicing + receipt features (see above) will be released in a couple hours.
It looks like Cinnicoin beat XC to the punch.
