Ok. My question is, what happened to SteamClient2.JobCallback between 1.5.1 and 1.6.0 as the ever so popular repo github.com/Jessecar96/Steambot is currently using 1.5.1.41089 and Bot.cs requires the JobCallback to authenticate with Steam.
Edit: Maybe posting on repo is better?
Edit2: Found the PR that explains it.
