 * Fixed an issue where `xportr_type` would overwrite column labels, widths, and "sas.formats"
+* Fixed messaging of `xportr_order`to give better visability of the number of variables being reordered.
+* Add new argument to `xportr_write` to allow users to specify how xpt validation checks are handled.
 * Fixed bug where character_types were case sensitive. They are now case insensitive.
 * Updated `xportr_type` to make type coercion more explicit.
