The last 8 gaps between All-In-One Security (AIOS) releases ran 4 to 71 days, typically 38 days. The latest line, 5.5.1, came out on 30 October 2026.
Counting on from there, and ignoring past gaps that are already shorter than the time that has passed, the most likely day is 7 December 2026, inside a window from 23 November 2026 to 7 January 2027.
