Avoid new slug generation while update (model.save)

[shrikantr-iprogrammer]

First I like to thankyou for create this beautiful plugin. When we do a insert operation it works fine. But at the time of update where I'm using findOne followed by Save it changes the slug again. I don't want slug fields to be changed ever. So can we avoid this?

There is a permanent flag, but it's not documented. You can see some docs for this flag in my fork's readme - it should work same in original plugin too.
