+- Reused cached character-dictionary media matches so loading a title with an existing snapshot no longer sends another AniList search request.

+- Used fresh mpv time-position, duration, and subtitle timing events for AniList post-watch threshold checks so progress updates still fire when playback reaches or skips past the watched threshold.
+- Prefer season-specific AniList search results for multi-season files before falling back to the base title.
+- Show a clear AniList message when the matched season is not in Planning or Watching instead of silently queueing an impossible progress update.

+- Hid the macOS visible overlay when mpv is no longer the foreground target so other apps and Spaces are not covered by SubMiner subtitles.
+- Kept the macOS overlay layered above active mpv while stats mouse passthrough is enabled, and treated the frontmost mpv app as the focus signal.
+- Opened the stats overlay inactive on macOS so it appears over fullscreen mpv instead of switching back to SubMiner's original desktop.
+- Preserved the active mpv focus state through transient macOS helper misses so subtitles do not flicker while mpv remains foreground.
+- Kept fullscreen macOS overlays stable when mpv remains frontmost but window geometry temporarily disappears from the macOS window APIs.
+- Released the macOS overlay when the helper reports mpv is no longer foreground so other apps are no longer covered.
+- Reduced macOS window-tracker background work by preferring the compiled helper and slowing polls while mpv is stably focused.

-- Avoided native `electron-updater` checks where they are unsafe, so tray and background update checks continue through GitHub release metadata without crashing the app.
+- Kept signed macOS app updates on the native updater path while preventing eager Squirrel install checks before the user confirms restart.
