1.1.0 IS the latest stable release. 1.0.1,1.2.0 and, 1.2.1 are all labeled beta on the FTB link i provided. The only one listed as release is 1.1.0. you can check this in the link provided by hovering over the letters to the left of each version. so by your admission, you only have the latest stable version, well youre hosting an old beta version. I also provided a picture of the site stating 1.1.0 is release not beta in case you dont actually want to check the link again.
