 **********
 
-Among other changes, this fixes the current ERRORs on the CRAN Package Checks with R-devel due to the change in `all.equal()` to compare environments now as well.
+Various minor updates.
+
+There are 3 WARNINGS right now in the CRAN checks, related to building one of the package Rmarkdown vignettes that depends on the DT package:
+
+`there is no package called 'webshot'`
+
