+## Highlights
+### Changed
+
+- **Subsync Reference & Target Picker**
+  - You can now choose both sides of a sync run: which subtitle is the timing reference and which one gets retimed.
+  - The video file itself can be used as the reference for local files (audio-based sync), though a subtitle track stays the default.
+  - Works for both alass and ffsubsync, and retiming the secondary subtitle track no longer overwrites your primary one.
+
+### Fixed
+
+- **Startup Logging**
+  - Background startup now respects your configured log level even when no `--log-level` flag is passed.
+- **Streaming Subtitle Tokenization**
+  - Jellyfin playback now seeds tokenization straight from the downloaded subtitle file, so episodes no longer fall back to slow, line-by-line tokenizing while waiting on playback events.
+  - Subtitle cues are no longer dropped when switching to a subtitle track embedded in the stream.
+  - Prefetching now runs through the whole episode instead of stopping once the cache filled, and the cache clears between episodes so slowdowns don't carry over to later titles.
+  - The tokenization cache was expanded from 256 to 2,500 lines, leaving more room for repeated lines (like openings and endings) to stay cached across episodes.
+- **Subtitle Line Display**
+  - Subtitle lines now appear immediately at their cue time even if tokenization hasn't finished, upgrading in place with annotations once ready.
+  - A failed tokenization attempt is no longer cached as plain text, so the line gets another chance at full annotations later.
