   If you are unable to reduce the generated file size, you can increase the `size_threshold` value to just above the maximum size, or disable the enforcement of size threshold checks altogether by setting `size_threshold = nothing`.
   If it is just a few specific pages that are offending, you can also ignore those with `size_threshold_ignore`.

-* Line endings in Markdown source files are now normalized to `LF` before parsing, to work around [a bug in the Julia Markdown parser][julia-29344] where parsing is sensitive to line endings, and can therefore cause platform-dependent behavior. ([#1906])
