 - `WAVE` parameters can be added to a `Wave` model with `add_wave_component()` in `wave.py` 
 - 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()`).
+- Upgraded versioneer for compatibility with Python 3.12
 ### Added
 - CHI2, CHI2R, TRES, DMRES now in postfit par files
 - Added `WaveX` model as a `DelayComponent` with Fourier amplitudes as fitted parameters
