No. You just need to see what is on the change log:
I when I modify the `galileo.cfg` (settings file) is when are added new cvars or options.
I when modify the `galileo.txt` (lang file) is when are added new LANG constants.
On this version I fixed a word misspelled, on the `galileo.cfg` but should have no impact.
