One possibility is to make use of pmwiki's XL function:
On page Site.Preferences or another page if you use a custom version,
add a key-value pair like

  'prog_version'   =>  '0.17',

Now you can use $[prog_version] on any page and pmwiki translates
(replaces) it with 0.17.
works even in Attach links like

   Attach:emusicj-$[prog_version].tar.gz

(note the square brackets, not curly ones)
