# Changelog

Kept as the work happens, not assembled at release time. Format is
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/); versions follow
[SemVer](https://semver.org/spec/v2.0.0.html).

**The `vX.Y.Z` tags already on this repository are upstream YTSage's**, inherited
with its history. SageTube's own versions start below and are the ones this file
records.

## 5.5.0 — 2026-08-09

### Added

- **The YouTube account is findable.** Signing in with browser cookies was
  reachable only via Downloads → *Custom Options* → *Login with Cookies* — the
  last tab — while the features that need it (the Feed's account mode, Search,
  Browse) are other tabs with no route to it, and the method that opens that
  dialog on the right tab had no caller at all. There is now an account button
  in the corner of the tab bar, visible from everywhere, showing whether
  cookies are in use and which browser they came from. The Feed offers the same
  thing beside its account mode instead of just greying it out, and now says
  why it is unavailable.
- **Cookie changes take effect immediately.** The player read them once, when
  it was built, so signing in only reached playback after restarting the app.
  It now reloads at the current position.
- **The player responds to the keyboard and the mouse.** It had a key handler
  for Space, F and Escape that could never fire — nothing in the player set a
  focus policy, so focus always landed on a child button or slider, which
  swallowed the keys. Now: Space/K play-pause, ←/→ ∓5s, J/L ∓10s, Shift+←/→
  ∓1s, `,`/`.` frame step, ↑/↓ volume, M mute, `[`/`]` speed with Backspace to
  reset, C subtitles, F fullscreen, Escape to leave, 0–9 to jump by tenths,
  Home/End, N/P for next and previous. Click pauses, double-click goes
  fullscreen, the wheel changes volume and Ctrl+wheel seeks, and right-click
  opens a menu built from the same table as the shortcuts. The bindings are
  scoped to the player, so typing in the Search box or the URL field is
  unaffected.
- **Previous, next and mute buttons**, and a buffering indicator — a stalled
  stream previously showed a frozen frame for 25 seconds with nothing on
  screen before the automatic retry.
- In fullscreen the controls and pointer fade out after a few idle seconds and
  return on any movement. In a window they never hide, so the layout does not
  jump.
- **Real icons.** The app had no icon system: transport buttons used the
  platform style's dark monochrome glyphs painted on saturated red, and
  everything else called an icon was an emoji baked into the English strings.
  A drawn SVG set is now rendered through QtSvg and recoloured at load — Qt
  stylesheets cannot recolour a `QIcon`, which is exactly why the old ones were
  unreadable. Buttons across the Downloads tab gained icons too.
- **Tooltips and accessible names on every button.** Three widgets in the whole
  application had a tooltip. An application-level polish filter now fills them
  in as each button is first shown, and swaps placeholder emoji for icons —
  which covers dialogs owned by upstream without editing them.
- **Skip this version** in the update dialog. The skipped version is never
  offered again; later ones still are.

### Changed

- **The tab order is Feed → Search → Browse → Downloads → Watch**, each with an
  icon, and the app opens on the Feed. Watch was first, which is where the
  other tabs send you rather than somewhere you start.
- **Opening the Feed refreshes it**, but only channels not seen for 30 minutes
  (`feed.auto_refresh_on_open_minutes`, 0 to switch off), at most eight per
  visit, once per interval per session, and after a short delay. A refresh is
  one yt-dlp subprocess per subscribed channel, so an unthrottled one would be
  a lot of them. The cached feed still appears instantly; manual Refresh always
  does everything.
- mpv is given an explicit `hwdec` list per platform (`player.hwdec`, default
  `auto`), each ending in software decoding, so a machine with broken GPU
  interop plays rather than showing a black frame. This does **not** silence
  `Cannot load libcuda.so.1` — that comes from the driver stack below mpv and
  appears with `hwdec=no` too.
- **The update check now looks at SageTube's own releases.** It queried PyPI's
  `ytsage` package for the version and `oop7/YTSage` for the changelog, then
  linked to upstream's downloads — a different program's release stream. It now
  reads `git.houmeres.sk/Houmeres/SageTube` releases, anonymously, and the
  "Download update" button opens this repository's release page.
- The beta channel follows SageTube pre-releases. Upstream's inherited `b` tags
  (`v5.3.0b` and earlier) read as pre-releases, so a stable instance cannot be
  offered one.
- The check now runs at most once a day rather than on every start.
- The About dialog and the update settings say SageTube rather than YTSage. The
  "Based on YTSage by oop7" attribution link stays — it is the MIT credit.
- Configs now carry `config_version`. A file written before 5.4.0 — including one
  inherited from an upstream YTSage install — has its stored `check_app_updates`
  cleared once, so SageTube's own default applies rather than a setting that
  pointed at another project's releases.

### Fixed

- The error log filled with hundreds of `after creating texture: OpenGL error
  INVALID_ENUM` lines per session. They come from the GL driver, playback
  continues regardless, and they buried the errors that do matter, so they are
  logged at debug level now.
- The player's cookie and proxy options were joined with commas and never
  escaped, so a cookie path or a proxy URL containing one silently truncated
  the option and produced a bogus one. The geo-bypass proxy was honoured by the
  downloader but never passed to the player at all.
- **The rest of the interface is themed.** `StyleSheet.MAIN` styled the window,
  inputs, buttons and tables and nothing else, so the main tab bar, combo
  boxes, sliders, lists, menus, splitters, tooltips and the horizontal
  scrollbar were drawn by the platform — the tab bar with white text forced
  onto system-coloured tabs, tooltips in the system's light style on a black
  app. All of them now match. `QFrame#tabContent` finally has the rule the tab
  widget's own comment promised.
- Checkboxes were round, which reads as a radio button — "one of these" rather
  than "on or off". They are square with a tick.
- Clicking any button shifted its label two pixels down and right, and clipped
  the artwork on fixed-width icon buttons: the pressed style changed the
  padding. The background change alone reads as pressed.
- The window icon shipped only at 48px and was upscaled everywhere; the 256px
  master now ships beside it. Its fallback was the platform's download arrow
  standing in for the application's identity.
- **The feed grid no longer flickers or loses your scroll position.** It was
  cleared and rebuilt from scratch after every channel finished, re-reading
  every thumbnail from disk each time; finished channels are now merged in and
  existing cards left alone. The docstring's claim that it "fills
  incrementally" is finally true.
- Card layout items accumulated: each `Load more` re-added cards the layout
  already held, and the resize check compared against `columnCount()`, which
  never shrinks — so it relaid out on every single resize event.
- Feed failures were invisible. The error was written into the same label the
  next successful channel immediately overwrote; the count is now reported once
  when the refresh ends.
- Switching the feed to account mode left the local videos on screen, so one
  mode's contents appeared to be the other's.
- Leaving the Feed tab or closing the window cancels a running refresh.
  `cancel()` existed and had no callers, so a sweep kept running and the window
  could be closed while its thread was live.
- Browse's Subscribe button never said "Unsubscribe", although pressing it
  toggles; its only feedback was a status line on a different tab.
- "Play all" quietly queued just the loaded page and claimed to be everything.
- The feed sorted by publish time and fetch time in the same expression, so the
  most recently refreshed channel floated to the top regardless of how old its
  videos were.
- **The player no longer crashes the app.** Qt destroys and recreates a
  widget's OpenGL context whenever it moves to another top-level window, and
  calls `initializeGL()` again. libmpv allows one render context per handle, so
  the second creation failed — and the failure path dropped the last reference
  to the *first* context while libmpv still held a function pointer into it.
  Python then collected the callback trampoline under libmpv's feet and the
  next frame notification jumped into freed memory. `initializeGL()` now tears
  down first so recreation is clean, teardown clears the callback and frees
  with the GL context current, and it is wired to
  `QOpenGLContext.aboutToBeDestroyed` so it runs before the context goes away
  rather than never. Verified over ten forced context destroy/recreate cycles.
- **Fullscreen no longer reparents the video.** It took the player out of its
  layout and into a new top-level window, destroying the OpenGL context twice
  per toggle — the most direct route to the crash above — and on the way back
  re-added the panel at the end of the splitter, so the video reappeared beside
  the queue with the pane sizes lost. The main window now goes fullscreen and
  the chrome around the video is hidden instead. Nothing is reparented.
- **Switching tabs no longer risks the player.** The cross-fade grabbed a
  screenshot of the outgoing page; on an OpenGL surface that forces a
  framebuffer readback and returns black, so the "fade" was a black slab and
  the readback endangered the context. Pages containing the video now switch
  without the fade.
- Dialogs dimmed instead of blurred while the player exists, for the same
  reason — every dialog in the app screenshotted the whole window.
- The saved volume never reached mpv: the slider set its restored value before
  its change signal was connected, so playback always started at 100.
- **The app no longer offers upstream YTSage's releases as its own updates.**
  `__version__` and `pyproject.toml` had been left at the scaffolded `0.1.0`
  while the released tag was `v5.4.0`, so every comparison against upstream's
  published version reported an update. Both now read `5.4.0`, the single
  source of truth for the window title, the About dialog and the update check.
- `ConfigManager` merged a stored config over the defaults **shallowly**, so a
  file written by an older build replaced whole nested objects: a stored
  `"player"` or `"feed"` containing only some keys silently discarded every
  default added since. The merge is now recursive. Keys present only in the
  stored file are preserved, so downgrading cannot destroy settings.
- Opening *Custom Options* and clicking OK re-enabled the update checker, because
  the settings tab read a missing `check_app_updates` as enabled and then
  persisted that reading unconditionally.

## 5.4.0 — 2026-08-08

### Changed

- The documentation left the repository: `docs/BUILDING.md`, `docs/UPSTREAM.md`
  and `docs/UPSTREAM_README.md` are now the
  [wiki](https://git.houmeres.sk/Houmeres/SageTube/wiki).
- **The history was deliberately not rewritten.** Every other repository in this
  org had its documentation removed from every commit on 2026-08-08. SageTube is
  a fork that still merges from `oop7/YTSage`, and a rewrite changes every commit
  id — which would end that. The files leave in an ordinary commit instead.
- `.github/` and `readme-translations/` are upstream's and were left alone, so
  the next merge does not conflict over them.
