The digital copy available from Ravelry should automatically update so long as the pattern is in your Ravelry Library. If you purchased the pattern as a print copy, or from my Etsy Shop, then you are in exactly the right place!
To find your version, look at the last page of the pattern. If there is no update date listed there, look at the file name of the .pdf.
