This should probably also bump the project version to something >0.2 (

libcbv2g/CMakeLists.txt

Line 4 in 784b3a5

VERSION 0.1

)

I agree.

Also, the origin hash needs to be updated:

Okay for me if it works in your SILs. I have no regressions in my (66) ISO 15118-2 samples, but they don't include any big integer examples.

Please fix the CMakeLists.txt though.

I've updated the hash (and added that it's from a unmerged branch) and bumped the version to 0.2.1, is that what you had in mind?

Exactly. Thanks!
