improve plex item change detection (#1659)

CHANGELOG.md

@@ -52,6 +52,9 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Fix path replacement logic when media server paths use inconsistent casing (e.g. `\\SERVERNAME` AND `\\ServerName`)
 - Fix *many* search queries, including actors with the name `Will`
 - Fix sqlite `database is locked` error that would crash ETV on startup after search index corruption
+- Fix bug where replacing files in Plex would be missed by subsequent ETV library scans
+  - This fix will require a one-time re-scan of each Plex library in full
+  - After the initial full scan, incremental scans will behave as normal
 
 ### Changed
 - Log search index updates under scanner category at debug level, to indicate a potential cause for the UI being out of date
