Changes in version 1.0.1 (2025-12-18) - Updates author metadata. Changes in version 1.0.0 (2024-07-15) - 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. Changes in version 0.1.7 (2020-03-01) - Patched release to fix tests on Solaris OS and removed test dependency on glmnet Changes in version 0.1.6 (2020-02-28) - First release to CRAN - Initial release supports linear and logistic hierarchical regularized regression
