[ Request ] Please annotate new features of Hack/HHVM with version numbers
Clearly showing which features of the Hack language are only available in hhvm 6 has become more important than ever. With the latest blogpost oss-update behind us, it is clear that building from source will be a requirement to both stay secure and to get access to the new features. For those of us who have stuck with hhvm 4.168, standing by for release[^1], it has become unclear which documentation applies to their version.
If this sentiment is shared, I'll retroactively add this information to documentation commits made this year. Would such a PR be accepted?
[^1]: I am making an effort to move away from hhvm 4 to hhvm 6. Anyone who has managed to build something recent, I'd love to know. I can truly use all the help I can get.
