Bugs That Persist (Unchanged in 2021)

• MicroSD card corruption on power loss: Still happens if you cut power while writing the index file. Use a high-endurance card (Samsung Pro Endurance or SanMax).
• Night mode switching delay: When the IR-cut filter activates, the screen still goes black for 0.5 seconds. No change.
• Time/date reset on deep discharge: If the backup battery (tiny coin cell) dies, the 2021 firmware still cannot keep time across power cycles. Annoying but not fatal.

Local Backup: Perform a manual configuration backup before applying the 2021 firmware or newer versions in case of a failed update. FW 6.3.0 Release Notes - Lucom MicroSD card corruption on power loss: Still happens
