+# 2023-1121-2325  `v1.9.20`  nice
+
+## new features
+* expensive subprocesses (ffmpeg, parsers, hooks) will run with `nice` to reduce cpu priority
+  * ...so listening to flacs won't grind everything else to a halt
+
+## bugfixes
+* the "load more" search results button didn't disappear if you hit the serverside limit
+* the "show all" button for huge folders didn't disappear when navigating into a smaller folder
+* trying to play the previous track when you're already playing the first track in a folder would send you on a wild adventure

+# 2023-1119-1229  `v1.9.19`  shadow filter
+
+## bugfixes
+* #61 Mk.II: filter search results to also handle this issue in volumes where reindexing is disabled, or (spoiler warning:) a bug in the directory indexer prevents shadowed files from being forgotten
+* filekeys didn't always get included in the up2k UI for world-readable folders

+# 2023-1118-2106  `v1.9.18`  cache invalidation
+
+## bugfixes
+* #61 search results could contain stale records from overlapping volumes:
+  * if volume `/foo` is indexed and then volume `/foo/bar` is later created, any files inside the `bar` subfolder would not become forgotten in `/foo`'s database until something in `/foo` changes, which could be never
+  * as a result, search results could show stale metadata from `/foo`'s database regarding files in `/foo/bar`
+  * fix this by dropping caches and reindexing if copyparty is started with a different list of volumes than last time
+* #60 client error when ctrl-clicking search results
+* icons for the close/more buttons in search results are now pillow-10.x compatible
+
+## other changes
+* `u2c.exe`: upgraded certifi to version `2023.11.17`
