OK, sounds good.

You would write something like:

  (define-public tryton-5
    (package
      (inherit tryton)
      (version "5.0.6")
      ;; …
      ))

and you only need to specify fields that differ from those of ‘tryton’.
See for example ‘guile-2.0.13’ in (gnu packages guile).

Right, and specifically there are no source file headers that say
“version 3 only”, so ‘gpl3+’ indeed!

Thanks,
