What Lineage OS 18.1?
As is the norm, with a major version number change comes a big platform update. While rebasing of the LineageOS Samsung SM-T500 Galaxy Tab A7 codebase atop Android 11’s source code does justify the “18” part, the subversion change involves something else. Instead of bumping up the minor version number, Google continues the tradition of rolling out big feature updates for new Android versions via “Pixel Feature Drop”. Hence, the LineageOS team has decided to jump up on the subversion, going from 18.0 to 18.1. Samsung SM-T500 Galaxy Tab A7
