How to update to Build 1109 ?

Ive just noticed that my build is 1108 and most other builds for online are running 1109.
Is there a reason that my build has not auto updated to 1109?
Im have a lifetime sub and switched over to steam just over a year ago, all automatic update settings are on so has the build 1109 been relesed on steam yet?

Ok, Ive just noticed the 1109v in the dropdown list in steam properties.

 

Sorry no screenchot

I think :
- open steam
- right click on rf2 ( at the top right)
- go to prorieties i think
- go to the tab "versions" or something like this
- choose beta 1109

 

Yep cheers, I literally found out how to do it 30 seconds after i did the post on the forum.
Thanks for the reply.

 

I don't have 1109 in this drop down list??? any help?

 

You should have 1109 and 1109_dx11_beta in the beta tab of rf2.

 

Ive just also noticed that my build is 1108 and most other builds for online are running 1109. i also dont have 1109 and 1109dx11 in the beta tab.. any help appreciated
