How do I publish my changes or preview a draft?

On a page that is already published, Save in the website editor puts your changes on the live page, in the classic editor and the visual editor alike. To work on changes without them going live, click Create a draft instead: the page then has a draft, marked Draft on the Pages list, and the live page stays as it is until you click Publish on the draft. Use the preview to see a draft first. A page that is not published yet saves as it is. You can roll back to an earlier version if needed.

In the visual editor, your changes are kept as you go and the bar says Not live until you save. Leaving without Save asks first. Opening a page on its own never makes a draft.

A draft stays current on its own: if the live page gets edited while a draft is open, those live changes are folded into the draft the next time you open it (your own draft edits always win), so publishing a draft never quietly undoes newer live work. The What changed link next to the Draft chip lists every difference before you publish.

To publish several pages at once, go to Entries then Pages, tick the pages you want, and press Publish Changes in the bar at the bottom. It counts how many of the ticked pages have edits waiting, and it skips any page that is already up to date. A page missing something required is named and left alone rather than published half finished. This is not the same as the Set Status control beside it: status decides whether a page is live at all, while Publish Changes sends out the edits sitting on top of it.
