[9.1.4] - 2026-05-28

Fixed

• Synced 6 accidental hooks.ts divergences from main: deviceId hex validation, proper gql.twitch.tv URL parser, missing worker function injections (_forceClearBackupCooldownsIfStale, _incrementPlaylistMediaSequence, _fetchWithTimeout), previousMediaKey cleanup with object-type guards

[9.1.3] - 2026-05-28

Fixed

• Consecutive ad stale stream: when a second ad arrives within the 8-second post-ad continuation window, the "buffer drain prevention" path and the 3-second backup search cooldown both served stale cached playlists from the previous ad cycle, causing the user to watch past stream content. Both paths now skip cached returns during post-ad re-entry so a fresh backup search runs immediately.

[9.1.2] - 2026-05-27

Fixed

• Low quality fallback toggle now correctly filters autoplay from backup search when disabled
• Reload trigger on fallback disable no longer blocked by unreachable pinned-type guard

[9.1.0] - 2026-05-27

Changes

• Real-Time UI controls: Settings toggles automatically grey out and disable when Ad Blocking is OFF, while preserving descriptive help popup interactions
• Auto Player Soft-Reload: Toggling Low Quality Fallback OFF during active backup playback now programmatically triggers a non-disruptive, soft reload of the Twitch player, instantly returning you to native source-tier quality
• Audited 11-Locale Translations: Perfected translation phrasing line-by-line in German (de), Spanish (es), Portuguese (pt), Italian (it), Japanese (ja), Korean (ko), and Russian (ru).
• Critical Fixes: Fixed the info modal Got It button click toggling settings off, and resolved the popup TDZ crash on declaration
• UI & Modal Layout Fixes: Relocated modals to prevent border-radius layout clipping, and fixed a load crash due to missing elements

[9.0.8] - 2026-05-23

Fixed

• Fix consecutive midroll backup contamination: BackupVariantUrls whitelist no longer cleared on ad-end reset, and cached encodings re-populate variant URLs prevents backup media playlists contaminating native snapshot across ad breaks

[9.0.7] - 2026-05-21

Changed

• Buffer monitor throttles to 900ms during steady-state playback — ~33% fewer ticks on healthy streams, stall detection latency unchanged in practice
• Cached React fiber root, container key, and player reference across transient skip ticks — eliminates fiber-tree re-walks after every ad break and idle interval
• HLS strip path: single combined regex for ad metadata, no redundant text.split, single-pass output build, hoisted per-line scan

[9.0.6] - 2026-05-21

Added

• Worker-hook coexistence with TwitchNoSub run TTV-AB alongside TwitchNoSub simultaneously

[9.0.5] - 2026-05-21

Fixed

• First poll now awaits backup search synchronously instead of fire-and-forget + stopgap — eliminates all ad-flash leakage paths on prerolls. Player sees loading spinner until clean backup arrives, then plays clean stream directly.

[9.0.4] - 2026-05-21

Fixed

-Stopgap during backup search now returns headers-only playlist on all requests — eliminates ad flash during prerolls

[9.0.0] - 2026-05-21

Fixed

• Ad-blocking pipeline restored to stable working version zero decoder corruption
• Fixed persistent buffering and slideshow playback during ad breaks on certain streams (#18)
• Empty playlist fallback returns original content instead of header-only to prevent player stalls
• Backup search now checks all 5 player types (including autoplay 360p) for clean streams
• Eliminated brief black screen when first loading a channel backup search now starts immediately with stripped native as stopgap (~100% faster channel load)

Added

• CSAI fast path for all-live ad breaks strips tracking URLs from native and returns directly with no stream switch
• Ad segment caching preserves playlist structure for stable playback

Rollback to last stable version while investigating the 8.x.x regression

[8.8.3] - 2026-05-20

Fixed

• CSAI Fast Path sticky loop: properly reset the CSAI flag when exiting early due to empty or too short playlists, preventing player buffer freezes.
• Fallback backup stream searching: reset the fallback filler count whenever a stripped playlist contains valid segments, preventing infinite token re-fetch loop locks.
• Midroll ad leakage: require refreshed backup stream playlists to be clean and verified, successfully blocking late-entering midrolls on stream switches.
• Vitest configuration type safety: standardized the mock AdSegmentCache in setup files to Map matching the production environment.

Changed

• Playlist parsing performance: optimized HLS segment cache validation by passing pre-split arrays directly to avoid redundant split overhead on large VOD files.

v8.8.1 — 2026-05-20

Fixed

• Stripped playlists now pass through even when identical to source — prevents false rejections
• Live-segment lockout cleared after empty playlist to allow recovery on next poll
• Fallback backup streams no longer mark the stream as using backup

[8.8.0] - 2026-05-19

Fixed

• Ad leak during backup search cached clean playlists served with incremented media sequences while worker searches for backup
• Worker hangs 3500ms fetch timeouts on all Twitch Usher, GQL, and stream requests
• Duplicate backup searches guard prevents redundant searches when multiple m3u8 requests arrive simultaneously
• Empty segments now created in-memory (Blob URL) instead of network fetch, eliminating round-trip delay during ad replacement
• Stripped ad segments insert alternating DISCONTINUITY markers to help the video decoder handle segment gaps
• Silent filler format changed from 2 long segments to 6 short 1-second segments with DISCONTINUITY for smoother recovery
• Backup search retry loop removed, fresh-token fetch cap added to prevent excessive API calls

Changed

• Ad spoofing now enabled by default — sends fake ad-watch beacons to reduce anti-adblock fingerprinting
• Build process auto-generates .xpi and source .zip during packaging
• Native recovery probe cooldown increased (250→500ms min, 750→1500ms default)
• Fast-fallback promotion policy default fixed, autoplay player type properly flagged for downstream recovery
• Low-latency recovery min clean playlists reduced (12→6) for faster post-ad resume
• Verbose token error payloads removed from backup search logs

[8.7.1] - 2026-05-19

Fixed
Autoplay (360p) backup — added as last-resort player type when all Source-tier types are ad-marked

Fallback filler cycle cap — prevents Error #2000 crash from indefinite silent filler loops

Force-strip CSAI segments — fallback path no longer leaks ad-marked content

Silent video filler — empty playlists serve valid MP4 segments instead of bare headers

Stripped playlist padding — prevents buffer underrun while backup loads

Automatic rollback based on version [8.0.0].

[8.6.8] - 2026-05-19

Fixed
Empty playlist after ad stripping now serves minimal HLS headers instead of ad-marked content

Misleading "Token relay error" log renamed to "Spoof relay error"

GQL ad spoofing timeout: 1500ms → 5000ms

[8.0.0] - 2026-05-18

Added
Ad Spoofing toggle in popup UI — control anti-adblock fingerprinting beacons independently

Ad Spoofing info modal explaining the feature

Translations for Ad Spoofing in all 11 supported locales

Changed
Backup ad-marked retry cooldown reduced from 15s to 5s — prevents stale playlist serving during contaminated backup cascades

Initial backup search runs as background fire-and-forget when cached content is available, eliminating buffer drain during mid-roll ad detection

Buffer Fix toggle hidden from popup UI (always-on internally)

Ad Spoofing defaults to off — users who want anti-fingerprinting coverage can enable it from the popup

Fixed
Backup playlist staleness: force-clears all backup cooldowns when cached playlist exceeds 8s, preventing expired-segment looping

Stream freezing/audio lag during ad transitions caused by blocked synchronous backup search and cooldown deadlock

Ad-completion spoofing beacons made user-controllable via popup toggle

[7.7.5] - 2026-05-17

Fixed
Brief loading circle during silent backup hold caused by 10s backup refresh letting HLS segments expire

[7.7.4] - 2026-05-17

Added
Ad-completion spoofing: mimics Twitch telemetry (impression, quartile, pod-complete beacons) to reduce anti-adblock fingerprinting

Fixed
Silent backup hold now capped at 2 minutes to prevent indefinite low-res playback

Ad recovery cascade after player reload: suppressed rapid backup type bouncing

Improved
Backup refresh during silent hold slowed from 1.5s to 10s to reduce network pressure

[7.7.1] - 2026-05-17

Fixed
Loading circle freeze during ad recovery: stale clean backup now served during search instead of falling through to ad-marked content

Improved
Faster stall detection and recovery: post-ad grace stall threshold reduced from 3 to 2 ticks, retry cooldown from 4s to 1.5s

[7.6.9] - 2026-05-17

Fixed

[7.6.5] - 2026-05-17

Fixed
Fire-and-forget ad segment fetches now use AbortController to prevent background resource waste

Transient backup search flags properly reset on ad-end state cleanup

Cache prune uses spec-safe collect-then-delete pattern instead of forEach+delete during iteration

Token fetch now retries up to 3 times with incremental backoff on timeout/network errors

CSAI playlists now strip ad segments during the poll-wait window while background backup search runs, closing a brief ad-leak gap on metadata-marked streams
