I have encountered an issue with the latest 2.20 and 2.21-dev versions of Mandelbulber. It seems that if I set the value for "distance between eyes" on the server machine, the parameter won't transfer to the client computers and they use the default value. I'm making stereoscopic VR content, so this parametere is really important in my use case and makes it so that I can't use the netrender function with stereoscopic content.

I don't know if it is ok to ask about new features in this post, but here goes anyway.
One feature that would be nice to have, is the ability to add different parameters to the animation dock keyframes. For example if I would like to keyframe global lighting changes or the amount of AA etc. Or in this case, change the optimal eye distance. It would also be nice to be able to automatically calculate optimal eye distances for each frame and save that value to keyframes. As is, there is only one value that can be set for the whole render and it can not be changed on the fly or automatically.

Biggest issue right now is the eye distance values not changing in the netrender clients.

I'm not sure what you are doing wrong. I have just checked and everything works fine with NetRender.
Why you think that distance between eyes is not transfered to the client? You not see correct value on client side or rendering is wrong. If first case, then everything is fine. Starting from 2.20 parameter values are not refreshed in UI on client side. It caused worse performance and problems with managing multiple CPU threads (NetRender works in separate CPU thread to improve performance of data exchange). However rendering on client side will be exactly the same as on server side.
You wrote that you want to add different parameters to keyframe animation. It is already possible. Just right-click on edit field for parameter which you wish to add

And use "Add to keyframe animation"

"Time Span"
