    The firmware 4.33(AAPJ.0) on is the latest official firmware which is officially verified before released.

    433AAPJ0ITS-WK19-r88384 is the date firmware. Our local support told me it is built based on the official firmware 4.33(AAPJ.0).

    If new bugs are found after 4.33(AAPJ.0) is released, the bug fix will be merged to the date firmware.

    I suggest you consult Zyxel support before upgrading to the date firmware.
