# Version Guard 0.78.4

Version Guard prevents older 0.78.x helpers from treating newer releases as failures.

Before 0.78.4, Runtime Preflight expected exactly `0.78.2`, so a correct `0.78.3` deployment could still show:

```text
app_settings.core_version is not 0.78.2
BALT_VERSION is not 0.78.2
```

0.78.4 changes this to version-aware checks:

- current bootstrap version must be compatible with current release,
- database `core_version` must be at least the current release,
- `core_version_0783` is true for any release `>= 0.78.3`, including `0.78.4`.

Older refresh helpers were also changed so they no longer downgrade `core_version` after 0.78.4 is installed.
