# Filter: gk/gravitycalendar/secret/allow-legacy

Whether to accept a calendar's previous secret, from before the per-site key.

It is the same on every site, so by default it is accepted only for calendars secured before the key, and only outside post content or in a post a calendar editor last saved or no one has changed since.

## Parameters

| Name | Type | Description |
|------|------|-------------|
| $allow_legacy | `bool` | Whether to accept the previous secret. Default: true only in the cases above. |
| $feed | `array` | The calendar feed. |

### Since
