Documentation: Should function documentation (etc.) include indication of what version the feature was added

[gwhitney]

And perhaps in addition, when the behavior changes, have some indication of which version the new behavior started? This could help if people are using a version different than what the current documentation is for (since unlike for some packages, there is no way to set the mathjs version in the documentation site to get the documentation for a specific version).

Ah, yes, that would be good to have. I think we can extend the comment section of all functions which is used to generate the documentation can be used for this. I think it would be useful to list when the function was introduced but also in what versions there where breaking changes.
