+# xrnet 1.0.0
+
+* Changes minimum supported R version 4.0.
+
+* Removes C++11 in SystemRequirements since it is guaranteed that R >= 4.0 that C++11 is minimum supported compiler. This also enables removing CXX_STD=CXX11 in Makevars and Makevars.win.
+
+* Fixes gcc-UBSAN errors detected in latest Rdevel checks. Note that these errors do not impact solutions. They occur when no external data matrix is provided and the underlying C++ code attempts to created a mapped matrix with a pointer to an empty matrix. Since the external data matrix is never used in this case, the resulting standard regularized regression with no external data still produces a correct solution.

 ## Submission
 
-This is a patch to fix the test errors generated on Solaris OS. 
+This is a major release that fixes gcc-UBSAN errors recently detected in r-devel and changes the minimum R version to be >= 4.0.
 
-* Checks reran on all other platforms as well
-
-* The test errors were due to incorrect comparison solutions being generated by another R package on Solaris.
-I now pre-generate comparison solutions and have removed the dependency on the other R package previously
-used to generate the comparisons. The changes did not require any modifications to the src code.
-
-* Removed glmnet from 'Suggests' in Description as package is no longer needed for tests. This allowed
-for the minimum R version to be changed from 3.6 back down to 3.5 to accomodate the old release as well.
+* Checks reran on all other platforms as well Rdevel to verify gcc-UBSAN errors were fixed for the case where we try to create a mapped matrix via a pointer to and empty matrix. The mapped matrix is now correctly created in the case the input is an empty matrix.
