Can't open 2.4.0-beta5 doc in 2.4.0-beta3

[Christopher Menzel]

LyX folk,

I recently compiled Lyx 2.4.0-beta5 under Linux and find that I am unable to open the file in Lyx 2.4.0-beta3 under MacOS and the conversion script is failing to export to 2.3.x. By changing "\lyxformat 618” to "\lyxformat 616” I was able to load the document in 2.4.0-beta3 although I got two "Document header” errors: "Unknown token: \use_formatted_ref \use_formatted_ref” and "Unknown token: 0 0”. After saving the file, it opened without any errors in beta3 and the contents appear to be OK. But I’d prefer a more elegant solution if one exists.

Thanks.
