A recent update to Confluence changed the way pages are saved/published after editing.  There are now two buttons: "Update" and "Save and Close".  It's not immediately apparent what these do.

My first guess was that "Update" would incorporate any changes published by my colleagues into the draft I'm currently working on.  Instead "Update" actually publishes the draft that you're currently working on.  Thus, the "Update" button would more clearly communicate its purpose with the text "Publish".

My first guess for the "Save and Close" button was that it would publish the draft I'm currently working on and return me to viewing the page.  This is similar to how Confluence previously worked.  Instead, this button saves the current draft and returns to viewing the current published version of the page.  This has confused some of my colleagues as well who frantically state that Confluence just lost all their work!  Instead of "Save and Close", this button should read "Save Draft and Close" (without the emphasis of course).

These changes would really help people understand what the buttons do and prevent literally hours of frustration from people re-creating all their work that is already available in a draft!
