Macues, Bixer and Catalina Security Up Dates

An apple to day released up dates for macues, bixer and macues catalina. The catalina up date is specifically labelled security up date, but it also says this up date has no published c ve entries. So not onlyyou sure what to make of this, but re something you do want to apply if you are still unning catalina or biker,. Doesn't appear to fix the wepkit, warnabily, that they patched last week.
