For example, I would like to find out if the function
mime_content_type
is deprecated.
In the English manual, it seems not marked as deprecated. This is also true for all other languages, except in German, Chinese and Spanish - there it is marked as deprecated.
How can I find out which manual is correct? Can I find maybe a history of the manual? So that I can see if it was once marked as deprecated and then the note was removed again?
