am I missing something or did he stop releasing linux versions after 9.1?

same for me - i dont find any newer version than 9.1 for linux - anyone can help?

This is because he was too greedy to buy a secure online sources files storage. He said he lost the sources because of HDD crash.

you've got to be kidding.. and he wasn't able to go redo his linux code from what's shared with the windows software?
