Missing Jacket
 

I don't know if there is some setting that has changed in version 5 and later but
jacket.xhtml is no longer written when converting an epub, even though the metadata is there.

Do you have the setting to insert metadata in the structure detection section of the conversion dialog enabled?

Thanks, Kovid

Actually, it wasn't checked now but it surely must have been checked before as all my books converted with versions previous to 5.x have the jacket. Just not those converted after upgrading to the 5.x branch.

Can confirm though that enabling it again it creates the jacket.

Great work, Kovid. Many thanks.
