In light of
>> There was one other comment I made (the seemingly lingering image.getCorrelatedNoise() method, or am I being dense about that?)

>Sorry, forgot to reply about that. We left it in, but marked it as discouraged, planned to be deprecated, in the pattern of other API changes we've been making recently.

I think this entry in the CHANGELOG seems a bit strong.  Suggest:
```
* The `image.getCorrelatedNoise` method is marked as discouraged, and is planned to be deprecated.  (Issue #527)
    * `image.getCorrelatedNoise()` should now be `galsim.CorrelatedNoise(image)`.
```
