Updation is not a word!

I was reading some source code recently and saw the word 'updation' used in a sentence (as in 'Failure in Updation of this product'). I paused for a moment ... that *almost* sounded ok, but clearly this is a an egregious error!

While Dictionary.com suggests that the word is somewhat valid, my preferred sites of Merriam-Webster and Oxford dictionary do not seem to agree. I should do the needful and perform a search and replace ;)
