Long time no see! v21.0 is the largest release in Magisk’s history. It comes with full Android 11 support (tons of stuff had to be rewritten from scratch!), and a completely redesigned Magisk Manager. These are the reasons why this particular public release took me over half a year to wrap up.
To the end user, not much has changed other than the fact that Magisk Manager has completely changed its appearance. However developers should pay attention to some changes due to adjustments for Android 11. Full changelogs are too massive to fit, so here I’ll point out the main changes and links to updated documentations.
The following are for advanced users/developer:
/sbinmay no longer exist. For developers, this means the Magisk’s internal
tmpfsdirectory is no longer always
/sbin, and instead randomly created every boot. To get the
tmpfspath, use the command
magisk --path(more details here). For custom kernel developers that uses
overlay.d, updated docs are here.
magiskpolicygained more features and some minor syntax changes, details here.
