Normally when you update the content of your book, you need to update the edition so you don’t confuse readers. Some updates on the content can be done without changing the edition, like correcting for spelling mistakes or grammatical errors [depending on who you publish with, this can be easily done.]. This is because it doesn’t change anything fundamentally in the story and improves the quality of the book. I would however caution you to not publish and then check for spelling or grammatical mistakes. You should aim to publish a completed and finished version of your book.
It happens that a typo appears that you didn’t catch before, but once your book is published, you should assume you’re done with that piece of work. Otherwise your mind will be thinking that you can always change it, and you will not be as thorough in your review before publishing it. And again, if you spend time reviewing and correcting errors in an already published book, that is time that you don’t spend on your next book or another creative project.
What if you’ve published your book, and you get a professional review that suggests changing some major aspects in the story, or polish specific things such as character development, world building, pacing; should you rework your book?
This is up for you to decide.
If you feel the professional is right and there are actually improvements you could make beyond “typo corrections”, then you may want to rework the book. You can take it off the market and relaunch it once you’ve done the changes. I would stick to the rule above to then change the edition just to avoid reader confusion.
There is nothing that says you have to do what the professional reviewer says. If you disagree with what they’ve highlighted as needing improvement, then that’s ok as well. It’s your book after all, and you should trust your instincts. What someone thinks of your book or art is subjective and you need to accept that not everyone will like it. Some criticism may be fair (fair as in constructive criticism that you can take on board) and some is simply derogatory and useless that you can (and should!) brush off.
