I have been a long time Visor/TotalTerminal user and wanted to try iTerm2 on 10.11 but was concerned with its use of the Sparkle updater framework. I could find no sign through all of my research if confirm if updates are performed through https instead of http and I declined to install it. I also couldn't find a way to contact the anyone to ask, so I'm glad you posted. So? What does it use? Don't you think this may be worth noting on the announcement or changelog?
