@@ -40,10 +40,14 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Artwork a publisher sends without an image type, or as `application/octet-stream`, is shown when it is a JPEG, PNG, GIF or WebP, instead of initials (#279).
 - A 429 from TypeSafe holds every call back as it asks, instead of the pass going on asking (#277).
 - Looking for items to read for Signals read every item on the server on each scan; it now reads only recent ones (#274).
+- With the downloads folder out of reach during a clean-up, as when the array stops, every downloaded episode was taken as deleted by hand and forgotten; the clean-up now leaves them alone until the folder is back (#293).
+- A feed address that serves something larger than 50 MB, such as an episode's file given as a feed, is refused as too large, instead of read whole into memory at every check (#295).
+- Searching items for `%` or `_` finds those characters, instead of treating them as wildcards that matched nearly everything (#296).
 
 ### Security
 
 - ammonia, which cleans publishers' HTML, updated to 4.2.4 for three advisories, among them XSS through SVG animation tags; rustls to 0.23.46 for five and h2 to 0.4.20 for one, in every connection ipx makes (#281).
+- The address of a file being downloaded, which for Patreon carries its signature, is sent to open pages and written to the log without its query, as other addresses already were (#292).
