 - Moved design matrix normalization code from `pint.fitter` to the new `pint.utils.normalize_designmatrix()` function.
 - Made `Residuals` independent of `GLSFitter` (GLS chi2 is now computed using the new function `Residuals._calc_gls_chi2()`).
 - Creation of `Fitter` objects will fail if there are free unfittable parameters in the timing model.
-- `TimingModel.designmatrix()` method will fail with an informative error message if there are free unfittable parameters in the timing model.
+- Only fittable parameters will be listed as check boxes in the `plk` interface.
 ### Added
 - CHI2, CHI2R, TRES, DMRES now in postfit par files
 - Added `WaveX` model as a `DelayComponent` with Fourier amplitudes as fitted parameters

 - Fixed an incorrect docstring in `pbprime()` functions. 
 - Fix ICRS -> ECL conversion when parameter uncertainties are not set.
 - `get_TOAs` raises an exception upon finding mixed narrowband and wideband TOAs in a tim file. `TOAs.is_wideband` returns True only if *ALL* TOAs have the -pp_dm flag.
