 ### Changed
 
+- Changed the solidity compiler pragma from `0.8.17` to `^0.8.8` for all files.
 - Improved type safety by using `abi.encodeCall` instead of `abi.encodeWithSelector` and the more explicit bracket syntax for permissions.
 - Bumped OpenZeppelin dependencies to `4.9.3`.
 - Refactored the fallback in the `isGranted` function in `PermissionManager` to make conditions mutually exclusive: Specific conditions answering `false` do not fall back to generic caller conditions (`_who: ANY_ADDR`) or generic target conditions (`_where: ANY_ADDR`).
