By the time the sub-version 5.13.5.1001 rolled out, the developers had ironed out the initial bugs of the Android 11 transition (which occurred in version 5.11) but had not yet introduced the more aggressive telemetry and cloud-save mandates of versions 5.14 and beyond.
Version 5.13.5.1001 is the "Goldilocks" build: It is based on Android 9 (Pie), which remains the most stable ABI for gaming. It supports 64-bit and 32-bit instances, offers the Eco Mode for multi-instance farming, and runs natively on Windows 10 and Windows 11 (including Hyper-V enabled systems).

Version 5.13.5.1001 operates within this framework, inheriting the core stability of the major version while introducing iteration-specific enhancements.
