 ## Fitting
 
 An important change to the functionality of `ssd_fit_dists()` was to switch from model fitting using [`fitdistrplus`](https://github.com/lbbe-software/fitdistrplus) to [`TMB`](https://github.com/kaskr/adcomp) to allow full control over model specification as well as improved handling of censored data.

+The change is internal and does not directly affect the user interface.
 Although it was hoped that model fitting would be faster this is currently not the case.
 
 As a result of the change the `fitdists` objects returned by `ssd_fit_dists()` from previous versions of `ssdtools` are not compatible with the major release and should be regenerated.

 In the first major update (v1), the dependency `fitdistrplus` [@fitdistrplus] was replaced by `TMB` [@tmb] for fitting the available distributions via Maximum Likelihood [@millar_maximum_2011]. 
 The move to `TMB` means the likelihood function is hand coded in `C++`, which allows full control over model specification and improved handling of censored data.
