Version 3.1-1

• Fixed: Cross-validation no longer fails when constant columns are present (thank you to Matthew Rosenberg for pointing this out)
• Fixed: Cross-validation no longer fails when group.multiplier is specified

Version 3.1-0

• New: Additional tests and support for coersion of various types with respect to both X and y
• Change: Convergence criterion now based on RMSD of linear predictors
• Change: 'Lung' and 'Birthwt' data sets now use factor representation of group, as character vectors are inherently ambiguous with respect to order
• Change: max.iter now based on total number of iterations for entire path
• Internal: 'X', 'group', and 'group.multiplier' now bundled together in an object called 'XG' to enforce agreement at all times
• Internal: new SSR-BEDPP feature screening rule for group lasso
• Internal: Registration of native routines
• Internal: Changing PROTECT/UNPROTECT to conform to new coding standards
• Fixed: The binding of X and G fixes several potential bugs, including Issue #12
