++## 9.7.4 (10/31/2024)
++### Bug Fixes
++* Fix a leak of obsolete blob files left open until DB::Close(). This bug was introduced in version 9.4.0.
++
+ ## 9.7.3 (10/16/2024)
+ ### Behavior Changes
+ * OPTIONS file to be loaded by remote worker is now preserved so that it does not get purged by the primary host. A similar technique as how we are preserving new SST files from getting purged is used for this. min_options_file_numbers_ is tracked like pending_outputs_ is tracked.
