Our developers reported that there are no Fairphone vendor patches for their Android 15 base since Sept 2025, so our 6.12 build has the latest available vendor security patches for the Android 15 base of iodéOS 6.x.
The bug of locked bootloaders not booting after updating to iodéOS 7.x on the FP4 have prevented us from releasing Android 16 based builds, so once that bug is resolved the upgrade to 7.x will happen (and thus the Android 16 vendor security patches will be incorporated).
