```

Signature types: [`TmuxVersion`](/en/haskell/latest/reference/libtmux-version-t-tmuxversion/), [`Either`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Data-Either.html#t:Either), [`VersionError`](/en/haskell/latest/reference/libtmux-version-t-versionerror/).

Admit every stable release from 3.3a through 3.8, including intermediate
 releases. Versions outside that range fail. Individual features need their own
 capability checks; passing this check does not qualify an entire release.
