Does the 1.9.10 change to chapter headings affect my PDF, EPUB or Kindle (AZW3) exports?

No. Version 1.9.10 only changes how the Word (DOCX) file is structured internally so that Kindle Create and Word's navigation pane recognise one numbered chapter per chapter. The PDF, EPUB, AZW3 and HTML exports are built separately and look exactly as before. If you publish through KDP, you can upload the EPUB directly, or open the DOCX in Kindle Create; both routes give you the chapter list with numbers.

A book disappeared from my Library but I never deleted it. Is my work gone? A chapter ignores its outline beats and writes the events of the following chapters. What can I do? A chapter or section heading ends up as the last line of a page in my export. How do I fix it? A chapter repeats parts of the previous chapter. Why does this happen and is it fixed?
