Changelog

Kept as the work happens, not assembled at release time. Format is Keep a Changelog; versions follow SemVer.

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.

Unreleased

Added

• 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 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.
• 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.
