 * `AIS_USE_SANITIZERS` now also enables the following sanitizers: integer, float-divide-by-zero, local-bounds, vptr, nullability (in addition to address, leak, and undefined). Sanitizers should also now emit usable stack trace info.
 * Added check in the Fastpath/AIS backend to ensure the HIP Runtime is initialized. This avoids causing a segfault in the HIP Runtime.
 * The default CMake build type was changed from `Debug` to `RelWithDebInfo`
+* Added `HIPFILE_UNSUPPORTED_FILE_SYSTEMS` environment variable to allow fastpath operations on unsupported file systems (defaults to false)
+* Added validation in Fastpath::score() to ensure the file is a regular file (not a directory, symlink, character device, etc.)
+* Added file system validation in Fastpath::score() to accept only ext4 file systems with ordered journaling mode and XFS file systems. Other file systems can be explicitly allowed via the `HIPFILE_UNSUPPORTED_FILE_SYSTEMS` environment variable.
 
 ### Removed
 * The rocFile library has been completely removed and the code is now a part of hipFile.
