A field the server is too old to have.

Constructed bare for parity with the Python library, which has this name and
throws it with no message. Constructed with its parts by this package, so a
caller filtering on a field their tmux predates is told which field, which
release has it, and which release answered — rather than being handed an
empty result that reads as "no object has this".

## Members

- `criteriaName` (attribute) — The criteria key the caller wrote, when this came from a query.
- `serverVersion` (attribute) — The tmux that answered, when this came from a query.
- `since` (attribute) — The first tmux that has the field, when this came from a query.
- `constructor` (method)
