 ## Changelog
 
-### 2.4.8 — 17.09.2026
-
-- Fixed `POST /media/verify` false-positive rejection: filenames containing a legitimate apostrophe (e.g. "La'An" in a Star Trek episode title) were blocked as "unsafe characters". Replaced the naive single-quote wrapping + apostrophe blocklist with proper `shlex.quote()` escaping for the remote ffprobe command; only newline/NUL byte injection is still rejected.
-
-### 2.4.7 — 17.09.2026
-
-- Added `POST /media/verify`: probes a media file's real duration via `ffprobe` (running inside the existing `bazarrUHD` container on `arrapps`, which already mounts `/data` and ships ffmpeg — no new service needed) and flags it as `suspect` when it deviates from an `expected_minutes` value beyond `tolerance_pct`. Catches truncated Sonarr/Radarr imports (e.g. a re-grab that lands as 1.8 GB instead of the expected 8 GB for a UHD episode) after the file is already on the NAS.
-
 ### 2.3.2 — 22.07.2026
 
 - Make Vaultwarden refresh durable: persistent named cache volume, protected runtime credentials, automatic API-key re-login and atomic cache writes.
