If you’re using the DEFAULT group in your cipher suite SSL definitions you can check the following articles and compare the versions for changes:

K13156: SSL ciphers used in the default SSL profiles (11.x - 13.x)

K54125331: SSL ciphers used in the default SSL profiles (14.x)

Another option is to run the following on each version and compare the output (you will need a BIG-IP running each version you want to check)

tmm --clientciphers DEFAULT

You can even check your cipher suites definition from your SSL Profile using that command just replace DEFAULT with your cipher suites definition and compare the output e.g.

tmm --clientciphers DEFAULT:3DES:!MD5
