While the templates for the most recent version of Thunderbird will probably also work with older releases of Thunderbird, they may contain new policies which are not supported in older releases. We suggest to use the templates which correspond to the highest version of Thunderbird you are actually deploying.
The following table states for each policy, when Thunderbird started to support it, or when it has been deprecated. It also includes all policies currently supported by Firefox, which are not supported by Thunderbird.
