-- `CITATION.rst` added to provide citing and credit information. [:pr:#130]
-- `segm_mask` can now take a list of labels which means it is possible to get multiple unmasked sources using `masked_segm_image` [:pr:#143]
-- Limits of param bounds in `get_default_sersic_bounds` changed.  [:pr:#143]

     - `r_eff` min bound set to `1e-3`.
     - `n` min bound set to `0.1`.
     - `ellip` max bound set to `0.99`.
-- Add `GenSersic2D` model, which is a Sersic model with generalized ellipse isophot (boxy) parameter. [:pr:#145]
-- Implement `PetroApprox` which is a class with no-PSF polynomials which relate profile paramters such as C2080 and Sersic n.  [:pr:#146]

 **PetroFit Enhancements**
 
-- Removed outdated `petrofit.utils.cutout` function. [:pr:#93]
-- `model_to_image` function upgraded to use `astropy.convolution.utils.discretize_model`. [:pr:#95]
-- `PSFModel` has been upgraded to `PSFConvolvedModel2D`.`PSFConvolvedModel2D` uses `__init__` function to wrap models. `PSFModel` class has been deprecated and will be removed in `v0.5`. [:pr:#100]
-- An `origin` parameter has been added to `petrofit.models.make_grid`. [:pr:#100]
-- `fitting.py` and `models.py` have been moved into a new `modeling` folder. This allows for all modeling functions and classes to be imported as `from petrofit.modeling import ...`. [:pr:#100] 
-- `petrofit.modeling.fitting.fit_model` can now accept fitting weights, so users can pass fitting weights using rms or error images. [:pr:#100]
-- `petrofit.modeling.fitting.plot_fit` now displays 3 panel image of fits (input image, model-image, and residual). [:pr:#100]

+- Removed kcorrect from Docker file. #77
 - Added badges to `README.rst`.
-- Implemented `get_amplitude_at_r` function that calculates the amplitude of an image at an isophotal radius. [:pr:#81] 
-- Removed outdated `fit_plane` function. [:pr:#84]
-- Moved requirements from `environment.yml` to `requirements.txt`. Though both can be used to install PetroFit, `environment.yml` is recommended at this time. [:pr:#72]
-- Upgraded circleci `resource_class` to `medium+`. [:pr:#62]
