As I was originally gathering all SFOS changelogs to determine which packages appeared / vanished / were updated by which SFOS release, a excellent baseline for SFOS 1.1.0.39 is provided by the SailfishOSS page on the MerProject Wiki, which also lists the licenses of all packages (proprietary or a specific FLOSS licence), which are installed by default.
All SailishOS release version numbers and their release dates are listed at whitesoft/sailversion by coderus.
