May I know which is upper version?

[소람5C2B]

Dear team,

May I know if Adobe Acrobat Pro 2017 is more advanced or upper version than Acrobat X? Found that if more upgraded than Acrobat X I can encrypt with AES256 thus would like to know if I can use encryption code AES256 when locking Adobe Acrobat Pro 2017 file.

Thanks

Acrobat X is several years behind Acrobat 2017.
