Lin545: My friends mentioned that Kerbal Space Program 1.3, released a few days ago, was available since day before yesterday on Galaxy - but its still 1.2.2 on WWW library.Thank you!
That was one of the main
selling point of Galaxy, it's one of the reason why it was created, to being able to have the patches faster than using offline installer.
Before Galaxy it was regularly days or even weeks after Steam that patches appeared on Gog; nowadays the patches appear on Galaxy
nearly on the same day than on Steam (or one year later if the game is called Darksiders 2....) and then a couple of days later it appears as offline installers (faster if it's a "critical" patch).
It's not some conspiracy, it's by design, as other have mentioned devs can upload their patches directly into Galaxy while the offline installers requires more manual work from Gog so it takes longer.
