-One important fix concerns the generation of previews. In certain cases, the
dvipng script will throw an error due to its inability to determine the

-The problem has been solved for dvipng versions >= 1.16. With earlier versions,

+One important fix concerns the generation of previews. In certain cases,
+LaTeX adds a temporary page at the end, and this confuses our python script
+that generates previews, making it unable to determine the pages to process
+through dvipng. This requires a re-run of LaTeX, which we can easily do. See:
+https://tex.stackexchange.com/questions/689978/why-does-temporary-page-error-occur
+A related problem has been solved for dvipng versions >= 1.16. With earlier
+versions, dvipng returns with an error code when some previews contain
+postscript specials, so that LyX will 'fall back' to the legacy method for
+generating all previews instead of only the ones with postscript specials.
+These will be of lower quality, and various messages will be output to the
+terminal. If this bothers you, please upgrade your version of dvipng.
