Explanation from Darrin in previous thread:
In general when we rev the version number of the document, we have changed the file format. (Usually only slightly.) But that means that older versions of the app will not be able to understand the data in it properly.
In this specific case, we did not change the file format in any way except for increasing the version number from 5.2 (I think?) to 5.5. The higher version number signals to FCPX to properly handle parameter supervision. In older versions of FCPX, parameter supervision in FxPlugs had some bugs, which meant you couldn't properly enable and disable or hide and show parameters on-the-fly. They would sometimes not update properly. We fixed this in 10.0.6, but several developers requested that we keep the old behavior for existing templates. We do that by checking the version number of the template. If it's < 5.5, we act in the old broken way. If it's >= 5.5, then we properly enable and disable parameters.
So you can change the version number back to 5.2 (or whatever Alex mentioned in his email), and older versions of FCPX will be able to read it, but newer versions will continue to exhibit the bug with parameter supervision. If you keep it as 5.5, newer versions will work properly, but older versions won't be able to open the file. In all other cases, you should never change the version number of a template manually.
With this in mind, we chose to make FCP 10.0.6 a minimum version for products released since December and it has only caused a couple of customer support issues.
