2) improved fit-to-page algorithm when either fitToWidth or fitToTall is unspecified

3) localize PDF bookmarks in the PDF bookmarks bar by taking into account the current formula language

4) improved position of pictures when rendering pages with repeat columns or rows

5) avoid picture duplicates in XLSX and XLSB files (and their variants, XLSM, XLST, ...)

6) merged cells pre-write for rendering needs
