Our R package, dexter, was first published on CRAN in February 2017, so he is not one yet, and this will be his first Christmas. Many good wishes to all of you, and we wish you a happy and prosperous 2018.
We seem to have a growing community in what are now 69 countries. We feel really honoured by the interest. The latest version, 0.6.0, has been published on CRAN a couple of days ago. It includes various enhancements to the ability estimation functions. It is now possible to generate score transformation tables and plausible scores on arbitrary item sets. More support for equating is expected to follow.
