The 4.20.00.35 changelog shows: ZIGBEE-700 Update default handling for NWKSTAT_SOURCE_ROUTE_FAILURE in the stack (http://software-dl.ti.com/simplelink/esd/simplelink_cc13x2_26x2_sdk/4.20.00.35/exports/changelog.html ). With previous simplelink versions we applied a manual modification highlighted below. Does this change (ZIGBEE-700) mean we don't need this manual modification anymore? I'm asking because there are no changes to this function in 4.20.00.35.
