BREAKING CHANGE

• Following version 2.0.0 of haven, labelled() and labelled_spss() now produce objects with class “haven_labelled” and “haven_labelled_spss”, due to conflict between the previous “labelled” class and the “labelled” class used by Hmisc.
• A new function update_labelled() could be used to convert data imported with an older version of haven to the new classes.
