+### File statistics cache is now memory-limited and managed by the
`CacheManager`
+
+The file statistics cache used by `ListingTable` is now memory-limited and
+centrally managed through the `CacheManager`.
+
+To configure the cache size use the `file_statistics_cache_limit` setting:
+
+```sql
+SET datafusion.runtime.file_statistics_cache_limit = '10MB'
+```
+
+To disable the file statistics cache, set the limit to 0.
+
+The file statistics cache is no longer created inside the `ListingTable`.
+Instead, it is created within the `CacheManager` and must be passed to the
`ListingTable`.
+
+**Who is affected:**
+
+- Users who want to limit the memory usage of the file statistics cache.
+- Users who want to disable the file statistics cache.
+- Users who want to create a `ListingTable` programmatically with a file
statistics cache.
+
+**Migration guide:**
+
+Disable the cache by setting the configuration value to 0:
