Property of [`RuntimeContract`](RuntimeContract.md) · stable · since 2.0.0

```ts
readonly documentVersions: {
  readonly min: number;
  readonly max: number;
};
```

The viewer-document versions this runtime reads: `{ min: 1, max: 2 }` in 2.0. Version 1 is read
only in the layers Holostep publishes; the page document your app passes must be version 2, so a
2.0 app requires version 2.

## Fields

<a id="min"></a>
### `min`

```ts
readonly min: number;
```

<a id="max"></a>
### `max`

readonly max: number;
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `documentVersions` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
