-## Minor release 0.15.6
+## Resubmission 0.15.6
 * I have addresed remaining issues in the vignette and the test cases that were still trying write to the user's library causing failures on debian-gcc on CRAN for version 0.15.5
 * I've tested with a read-only system and user R library to simulate the errors on the debian system.
-* There is one remaining NOTE that is due to the way we load and test a package (using loadNamespace) built by DataPackageR in the vignettes.
 
 ## Test environments
 * local OS X install (x86_64-apple-darwin16.7.0), R 3.6.0  (2019-03-07 r76210)
