Suppress useless warnings caused by uninititalised object handles that are correctly uninitialised caused by error conditions failing prematurely. Fix logdbg to show the type of message in debug. --- diff --git a/Changes b/Changes index 74c07256..840bcdc0 100644 --- a/Changes +++ b/Changes @@ -1,3 +1,9 @@ +17Mar23======================================================================= +1.
