 ## v0.8.0 (2026-03-22)
 
+### Added
+- Overlay: Added the subtitle sidebar feature with a new `subtitleSidebar` configuration surface.
+- Overlay: Added a sidebar modal with cue list rendering, click-to-seek, active-cue highlighting, and embedded layout support.
+- IPC: Added sidebar snapshot plumbing between renderer and main process for overlay/sidebar synchronization.
+
 ### Changed
-- Docs: Refreshed the vendored Texthooker docs/index.html bundle to match the latest local build artifacts.
+- Config: Added hot-reloadable sidebar options for enablement, layout, visibility, typography, opacity, sizing, and interaction behavior (`autoOpen`, `pauseOnHover`, `autoScroll`, toggle key).
+- Docs: Added full `subtitleSidebar` documentation coverage, including sample config, option table, and toggle shortcut notes.
+- Runtime: Improved subtitle prefetch and rendering flow so sidebar and overlay subtitle states are kept in sync across media transitions.
 
 ### Fixed
-- Anki: Known-word cache refreshes now reconcile Anki changes incrementally instead of wiping and rebuilding on startup, mined cards can append their word into the cache immediately through a new default-enabled config flag, and explicit refreshes now run through `subminer doctor --refresh-known-words`.
-- Subtitle: Restored known-word coloring and JLPT underlines for subtitle tokens like `大体` when the subtitle token is kanji but the known-word cache only matches the kana reading.
-- Stats: Episode progress in the anime page now uses the last ended playback position instead of cumulative active watch time, avoiding distorted percentages after rewatches or repeated sessions.
-- Stats: Anime episode progress now keeps the latest known playback position through active-session checkpoints and stale-session recovery, so recently watched episodes no longer lose their progress percentage.
-- Stats: Anime episode progress now falls back to the latest retained subtitle/event timing when a session is missing a persisted playback-position checkpoint, so older watch sessions no longer get stuck at `0%` progress.
-- Overlay: Kept subtitle sidebar cue tracking stable across transitions by avoiding cue-line regression on subtitle timing edge cases and stale text updates.
-- Overlay: Improved sidebar config by documenting and exposing layout mode and typography options (`layout`, `fontFamily`, `fontSize`) in the generated documentation flow.
-- Overlay: Added `subtitleSidebar.autoOpen` (default `false`) to open the subtitle sidebar once during overlay startup when the sidebar feature is enabled.
-- Overlay: Made subtitle sidebar resume/start positioning jump directly to the first resolved active cue instead of smooth-scrolling through the full list, while keeping smooth auto-follow for later cue changes.
+- Overlay: Kept sidebar cue tracking stable across playback transitions and timing edge cases.
+- Overlay: Improved sidebar resume/start behavior to jump directly to the first resolved active cue.
+- Overlay: Stopped stale subtitle refreshes from regressing active-cue and text state.

 # Changelog
 
 ## v0.8.0 (2026-03-22)
-- Refreshed the vendored Texthooker docs/index.html bundle to match the latest local build artifacts.
-- Added incremental known-word cache refresh behavior so mined cards can append cache entries immediately and `subminer doctor --refresh-known-words` is now the explicit full refresh path.
-- Fixed known-word/JLPT subtitle styling so tokens like `大体` keep expected coloring even when only the kana reading is in cache.
-- Fixed anime progress to use last ended playback position and keep latest known checkpoint across sessions, preventing stale or zero percent regressions.
-- Kept subtitle sidebar cue tracking stable across transitions and improved sidebar configuration documentation for `layout`, `fontFamily`, and `fontSize`.
-- Added `subtitleSidebar.autoOpen` to open the subtitle sidebar at startup when enabled.
-- Improved sidebar resume/start behavior to jump directly to the active cue on resume while preserving auto-follow smooth motion.
+- Added a configurable subtitle sidebar feature (`subtitleSidebar`) with overlay/embedded rendering, click-to-seek cue list, and hot-reloadable visibility and behavior controls.
+- Added release docs updates for sidebar configuration, including options, sample config, and toggle shortcut behavior.
+- Synced sidebar and overlay subtitle states during playback transitions via IPC-backed snapshot plumbing.
+- Fixed sidebar cue tracking to remain stable across timing edge cases and stale subtitle refreshes.
+- Improved sidebar resume/start behavior by jumping directly to the first resolved active cue.
