 #Status
-This project is now in what i'd consider v1 stage as such i dont believe there is much to add to stratum. so as of now this code is in bug fix stage only and should be considered unmaintained. 
+Riecoin support just implemented, needs testing.
 
 #Description
 Stratum-mining is a pooled mining protocol. It is a replacement for *getwork* based pooling servers by allowing clients to generate work. The stratum protocol is described [here](http://mining.bitcoin.cz/stratum-mining) in full detail.
