+## 0.3.0 — 2026-07-27
+
+- Make imported media and browser-native duration/dimensions available without
+  loading FFmpeg, so recognized files can start playback immediately.
+- Move authoritative codec, stream, chapter and tag inspection to explicit or
+  operation-driven demand; keep playback usable after inspection failure and
+  expose bounded retry controls.
+- Inspect automatically when Quick Convert, preview proxies, timeline renders
+  or advanced tools require authoritative details, while preserving
+  deterministic multi-file timeline order.
+- Recover Firefox probes with a fresh same-mode core, safe MT-to-ST fallback
+  and operation reservations that prevent concurrent mounts or preference
+  changes.
+- Add Chromium and Firefox evidence proving the supplied 153 MB, 43-minute
+  lecture plays before detailed inspection and retains the same media element
+  afterward.
