I have at last gathered all publicly available winmx clients and decided to make this list of them with their hashes for others to reference against along with the release dates.

All the clients on this list are available from the archives still.
There are a few early releases but as they came out in 2000 I dont think I,ll ever see any of them
Big thank you to 7en for his donation of some of the missing versions and the layout idea
