- Apps can specify task stack depth and preferred memory placement in their manifests. - App identifiers are validated against length and character requirements. - Crash diagnostics now show the crash cause, reason, fault address, call stack, and program-counter details, with logs saved for review. - App closing is more consistent across built-in screens. There's now a dedicated function, and the old _emit() function is made private. - Crash diagnostics no longer display a QR code without a call stack. - Improved memory allocation for unrestricted requests.
