Subject: [PATCH] Version 1.53: Updated the definitions of the KEY_PAGE_UP and
KEY_PAGE_DOWN variables to match what they are in sbbsdefs.js (if defined)
from December 18, 2017 so that the PageUp and PageDown keys continue to work
properly. This update should still also work with older builds of
Synchronet.
