Just run the game and let it update.  The patch for 20 was small.
I am not putting out multi-version patches, unless it is absolutely necessary.  It gets to be a logistical nightmare.
Are you have an issue with the auto-updater?  If so, I would like to know what it is.  You can get the patch links from the previous posts, or I can get them to you if you have to go that way.
