 * Support configurable number of threads for scanning and generation.
 
 ### 🐛 Bug fixes
+* Prevent cover image from being incorrectly regenerated when a scene file's hash changes.
 * Fix version check sometimes giving incorrect results.
 * Fixed stash potentially deleting `downloads` directory when first run.
 * Fix sprite generation when generated path has special characters.
