1.6.0Beta5 G729

I have a license for G729 form Digium. It was working fine with 1.4. It showed 10 codec available with show g729. I upgraded to 1.6.0 Beta5 and now there is no ‘show G729 command’. I was unable to locate a directory to download the codec_g729a.so for V 1.6.0 so I am using the latest v34 from the 1.4 directory. Should this be correct? Why would my g729 not be working with the upgrade to 1.6?
