Tip of the Day: Don't rush to hit the "publish" button. EDIT! | Black Wolf Editorial

Yes, the likes of Amazon's KDP have made it easy to upload revisions should the need arise; however, if you edited correctly in the first place, it wouldn't be necessary. Mistakes will still slip through — no book is completely error-free, but publishing is a business, so treat it as such. Traditional publishing houses don't take a published work out of print to edit it, reposting a new version weeks later, so why should you?
