When the original Amiga 1000 was released, it shipped with version 1.0 of Kickstart and Workbench. However, it wasn't long before Commodore released version 1.1 and computers started shipping with the newer software.
Looking at early magazines from the period, readers with version 1.0 were advised to visit their local dealer to get a 'copy' of version 1.1.
Later, when versions 1.2 and 1.3 were released, an end-user could purchase an 'Enhancer' kit from Commodore with the new disks and documentation.
I'm curious what the official upgrade route was from 1.0 to 1.1. Did Commodore simply allow end users to copy the new Kickstart/Workbench disks free of charge (figuring it would cost them little and be convenient for users)? Or perhaps original 1.1 disks were mailed to existing users free of charge? Or was an 'Enhancer' kit (similar to 1.2/1.3) made available for purchase?
The anecdotal evidence I have seems to indicate Kickstart/Workbench 1.1 was simply given away to (the relatively few) existing owners. Can anyone speak definitively (personal experience or cite some official source) on this?
EDIT
I have posted a partial answer to my question below, but I'm going to leave this open. My hope is someone that actually received disks from Commodore will be able to confirm what I think I know, and also it would be interesting to know what a user actually received from Commodore. (just disks? a cardboard case? printed materials? etc).
