Once you narrow down what you’re looking for, maybe ask a more specific question.
There were lots of changes to taps, sharpness calibration of CRT-Guest-Advanced-NTSC, Chroma/Blending, the way custom and preset settings are enabled via the NTSC Resolution Scale, behaviour of rainbow effects. In general, all of my NTSC presets might look more blurry than intended and possibly less saturated in post 1.14 versions.
Even Mask Stagger has been replaced leading to less fine tunability of Shadow Mask settings while making it simpler for a noob to turn on the Shadow Mask.
In my opinion many of the changes which have come from user feedback might sometimes be a bit premature. I tend to try to milk whatever look I’m going for for quite some time using what is available before asking for things to be hard coded in the shader.
In short newer isn’t always better and updating for updating sake (just to stay up to date) is sometimes counter-productive or futile, especially if the updates break something that was basically at an almost perfect steady state.
Think about it this way, how often do you need to update your CRT?
Anyway, that’s merely my opinion.
For the changes to hue, you can read all about those on Dogway’s Grade thread.
My presets, were never designed with the new Grade in mind.
So in general it’s a big mess trying to keep these presets up to date in lock step with the latest Shader changes and many of the updates are not necessary in the context of the preset pack and many times end up making things look worse than before. Then it’s a fight to try to get things close to back to what they were before when all that’s really needed is to revert to a previous version of the Shader and everything looks great again.
