Audio for pages built with the Divi builder no longer reads out raw layout code. On some Divi pages the audio would speak module settings (for example "et pb section builder version 4.16 background color gradient...") mixed in with the text. Only the real page content is read now.
When the player placement is set to "Before excerpt" or "After excerpt", the player now appears on single posts and pages. Previously it only showed on layouts that display an excerpt, so on a normal single post or page no player was shown.
