 - Added new experiment models for RIDME on systems with one to seven harmonic pathways (S=1/2 to S=7/2) to include all higher harmonics (overtones) ([#79](https://github.com/JeschkeLab/DeerLab/pull/79)). 
 - Bootstrapping is now embedded into ``fitmodel`` to automatically bootstrap all output quantities without the need to write additional script lines ([#55](https://github.com/JeschkeLab/DeerLab/issues/55)). In ``fitmodel`` a new option ``uq`` allows to switch between covariance or bootstrapping uncertainty quantification ([#88](https://github.com/JeschkeLab/DeerLab/pull/88)). 
 - The function ``fitmodel`` now returns ``Vmod`` and ``Vunmod``, the modulated and unmodulated contributionsto the fitted dipolar signal, respectively, along their uncertainties as additional outputs ([#78](https://github.com/JeschkeLab/DeerLab/pull/78)).
-- Implemented initialization strategies in ``fitmultimodel`` for multi-model components ([#67](https://github.com/JeschkeLab/DeerLab/pull/67)). Three different new strategies ``'spread'``, ``'split'`` and ``'merge'`` will initialize the parameter values of the N-component fit based on the results of the N-1/N+1 component fit to improve quality of results and speed.

 - Added contribution guidelines to the documentation and automated list of DeerLab contributors. 
 - The function ``snlls`` now accepts additional custom penalties to include in the optimization ([#76](https://github.com/JeschkeLab/DeerLab/issues/76), [#108](https://github.com/JeschkeLab/DeerLab/pull/112)).

 - Adapted piece of code leading to a ``VisibleDeprecationWarning `` visible during execution of certain DeerLab functions.
 - Improved interface of built-in plots in ``FitResult.plot()``. The method now returns a Matplotlib figure object (`matplotlib.figure.Figure`) instead of an axes object (``matplotlib.axes._subplots.AxesSubplot``) which can be modified more freely to adjust graphical elements ([#85](https://github.com/JeschkeLab/DeerLab/issues/85)). The method now takes an optional keyword ``FitResult.plot(show=True\False)`` to enable/disable rendering of the graphics upon calling the method ([#87](https://github.com/JeschkeLab/DeerLab/pull/87)).
 - The fit objective values returned in ``FitResult.cost`` are now correct (previous versions had an erroneous 1/2 factor) ([#80](https://github.com/JeschkeLab/DeerLab/issues/80)). The value is now returned as a scalar value instead of a single-element list ([#81](https://github.com/JeschkeLab/DeerLab/issues/81)).
-- Removed the re-normalization conventions ``K(t=0,r)=1`` and ``B(t=0)=1`` and associated options ``renormalize`` and ``renormpaths`` in the ``dipolarkernel`` and ``dipolarbackground`` functions ([#99](https://github.com/JeschkeLab/DeerLab/pull/99)) to avoid redundance issues between dipolar pathway amplitudes and signal scales ([#76](https://github.com/JeschkeLab/DeerLab/issues/76)). 
+- Removed the re-normalization conventions ``K(t=0,r)=1`` and ``B(t=0)=1`` and associated options ``renormalize`` and ``renormpaths`` in the ``dipolarkernel`` and ``dipolarbackground`` functions ([#99](https://github.com/JeschkeLab/DeerLab/pull/99)) to avoid identifiability issues between dipolar pathway amplitudes and signal scales during fitting ([#76](https://github.com/JeschkeLab/DeerLab/issues/76)). 
 - The fit convergence criteria ``tol`` (objective function tolerance) and ``maxiter`` (iteration limit) are now exposed as keyword argument in all fit functions ([#111](https://github.com/JeschkeLab/DeerLab/issues/111), [#112](https://github.com/JeschkeLab/DeerLab/pull/112)).
