You probably mean 1.6, not 1.8. But yes, we'll look into updating / ugprading. As a general rule we try to keep any formats we support up to date.

The jury is still out on MVR-xchange though, which is more of a file transfer feature than a file format.

You are right, I misread the version number.
For us it is super important to have as much interoperability via mvr. Having it in real time is nice to have but not as important as being able to back and forth between one or more other programs and Capture.
