I just installed scalingo and here are the first problems I encountered:
Fail to open log file: /home/geoffroy/.config/scalingo/local.log, disabling logging.
Fixed with mkdir ~/.config/scalingo
Your Scalingo client (1.0.0-alpha1) is obsolete, some feature may not work correctly, please update to '1.0.0-alpha2'
But I downloaded (and re-downloaded) version 1.0.0-alpha2, the version must not have been updated in the binary.
Fixed in alpha3
