+Release ``v1.2`` - June 2026
+------------------------------------------
+- |feature| : `modelUncert` is now returned in the `FitResult` object
+- |feature| : Added new saving and loading options for `FitResult` and `UQResult` objects, using `save` and `load` functions.
+- |feature| : Added new automatic calculation of background function with `dipolarbackgroundmodel` function. Added `FitResult.bg` and `FitResult.bgUncert` attributes to store the fitted background function and its uncertainty, when possible.
+- |feature| : Added multi-core parallelization to the `profile_analysis` function via the `cores` argument.
+- |feature| : Added a new `show_config` function to display deatils about how DeerLab is configured in the current system.
+- |fix| : Fixes issues with bootrstrap uncertainties
+- |api| : N bootstrap samples no longer produces N+1 samples
+- |enhancement| : Support Python 3.13 and 3.14
+- |fix| : All gaussian models now normalise to 1
+- |fix| : Fixed bug in `ex_fitting_5pdeer_pathways` so scales are now correct on the pathways. 
+- |api| : Models are now deepcopied on import to avoid issues with users modifying the built-in models. 
+- |fix| : Fixes bug where some parameters frozen before the `dl.dipolarmodel` function were not frozen in the resulting model.

+DeerLab Version 1.2
+========================
+
+DeerLab version 1.2 is a major update which brings a number of new features and improvements to the library. The most significant changes include:
+- **Background model support in fit results**: When fitting a dipolar signal model that includes a background component, the fit results now include the evaluated background signal and its uncertainty. This allows users to easily access and analyze the background contribution to their fitted models.
+- **Saving and Loading of Fit Results**: The fit results can now be saved to and loaded from disk, allowing users to preserve their fitting outcomes and share them with others.
+
+The following sections provide more details on these new features and how to use them effectively in your analysis.

+Plotting the dipolar spectrum / Pake pattern
+-------------------------------------------------------------------------
+
+The dipolar spectrum or Pake patern is the Fourier transform of the dipolar signal, and can be useful for visualising the dipolar frequencies present in the signal. We can also overlay the dipolar spectrum of the fitted model to see how well the fit captures the dipolar frequencies in the data.
