# GriefPrevention3D v17.5.4
**Wiki:** https://github.com/castledking/GriefPrevention3D/wiki
## Highlights
- **Restored `ClaimPermission.Inventory` for plugin compatibility** - External plugins like BiggerBarrels that reference `ClaimPermission.Inventory` will no longer crash with `NoSuchFieldError`.
- **Added deprecation notice** - `Inventory` is now a deprecated alias for `Container`; plugin developers should migrate to `Container` for future compatibility.
## Bug Fixes
The enum constant `ClaimPermission.Inventory` was removed during previous refactoring work, breaking plugins compiled against older versions of GriefPrevention3D. This release restores it as a deprecated alias pointing to `Container`.
Plugins affected:
- BiggerBarrels (and any plugin referencing `ClaimPermission.Inventory`)
The fix ensures backward compatibility while guiding developers toward the new `Container` permission name.
## Pairing
This release pairs with **GPExpansion v1.1.1** for the new claim block accrual profile controls documented at:
https://github.com/castledking/GPExpansion/wiki/Claim-Block-Accruals
## Migration
No data migration required. Existing configs are unchanged.
**Note for plugin developers:** Update your code to use `ClaimPermission.Container` instead of `ClaimPermission.Inventory`. The `Inventory` constant will be removed in a future major release.
