Extends the engine-neutral PlayerController contract with capability-gated external subtitle loading, subtitle delay adjustment, and subtitle styling (size/color), rendered in the shared subtitle popover: - Contract: new externalSubtitles/subtitleDelay/subtitleStyle capabilities, subtitleDelaySeconds + subtitleStyle state, addExternalSubtitleFile/ setSubtitleDelay/setSubtitleStyle commands. subtitle-style.ts owns presets, clamping, and localStorage persistence of size/color (shared across engines, volume-key precedent); delay and the loaded file stay per-session. - HTML5 + ArtPlayer (shared-controls mode): renderer-side .srt/.vtt picker (no filesystem path enters the app), SRT/VTT cue parser, external files rendered as native TextTracks merged into the track list with exclusive selection, exact cue re-timing for delay (gated on a loaded file), and scoped ::cue styling. - Embedded MPV frame-copy: new sub-add/sub-delay/sub-scale/sub-color helper protocol commands, main-process subtitle file dialog (.srt/.ass/.ssa/.vtt/ .sub; mpv renders ASS natively), new IPC channels + preload + bridge API, renderer-side delay/style ownership with per-session reset and persisted style re-application. - Video.js shared mode, vendor-chrome paths, native-view, and the Linux out-of-process path advertise no capability and render no UI. Adds focused specs for the parser, external-subtitle session, style helper, web adapter, popover interactions, embedded settings, command-runner IPC, and frame-copy protocol lines; updates all 19 i18n files, the player-controls contract doc, CLAUDE.md, and a release note.

Release notes (.changes/)
Every PR with a user-visible change drops one file here describing that change
in plain language. At release time
tools/release/build-release-notes.mjs turns the accumulated files into the
GitHub release body, the CHANGELOG.md section, and a blog-post scaffold for
the website — then deletes them.
The point is to write the note while the context is still fresh, instead of reconstructing three months of work from commit titles at release time.
File
Name it <area>-<short-slug>.md, e.g. .changes/playback-up-next-rail.md.
---
type: feature
area: playback
issues: [1187]
screenshot: up-next-rail
---
Series now show an "Up Next" rail beside the player on wide windows: the rest
of the current season, watch progress, and click-to-play inline.
| Field | Required | Value |
|---|---|---|
type |
yes | breaking, feature, fix, perf, or internal |
area |
yes | lowercase slug, same as the conventional-commit scope |
issues |
no | issue numbers this closes — [1187] or 1187 |
screenshot |
no | slug from tools/release/screenshots.manifest.json |
There is no version field. The release version is chosen deliberately at release time, not derived from these files.
You never write a PR number: the generator resolves it from the commit that added the file.
Writing the body
One to three sentences, present tense, written for a user, not a reviewer. The body is capped at 400 characters — depth belongs in the blog post.
-
❌ "Refactor
WebVideoControlsAdapterto hoist volume state into the session" -
✅ "The player now remembers volume between episodes"
-
❌ "Fix off-by-one in
resolveEnrichmentSeasonNumber" -
✅ "Series whose title carries a season marker no longer show the wrong season"
type: internal records invisible maintenance. Internal notes stay collapsed in
CHANGELOG.md, are omitted from the blog scaffold, and are removed from the
authored public GitHub body by
extract-changelog-section.mjs --public. GitHub's generated commit list remains
separate. An internal-only release can therefore have an empty authored body.
When a note is not needed
The gate auto-exempts website, E2E and mock-server apps, *.spec.{js,ts},
*.e2e.{js,ts}, snapshots, any /testing/ path, and Markdown. For other
test-only, documentation, CI/workflow, or pure-refactor changes under
apps//libs/, apply no-release-note when no user-visible note is warranted.
Commands
pnpm run release:notes:validate
pnpm run release:notes:github
pnpm run release:notes:changelog
pnpm run release:notes:blog
node tools/release/build-release-notes.mjs --consume
The release version comes from the root package.json — bump it first, then
generate. --version 0.24.0 overrides it to preview a release before the bump:
pnpm run release:notes:github --version 0.24.0
A bare -- separator is accepted and ignored, so the npm habit of
pnpm run release:notes:github -- --version 0.24.0 works too: pnpm forwards
that separator to the script rather than consuming it the way npm does.
--validate and --format github only read and print. --format changelog
and --format blog write their target file (rerunning changelog for the same
version replaces that section rather than duplicating it). Only --consume
deletes anything.
The release sequence is: bump the version → release:notes:changelog →
release:notes:blog → --consume → commit → tag → push. The tag build then
extracts the new CHANGELOG.md section into the GitHub release body
(tools/release/extract-changelog-section.mjs) and fails the release if
the section is missing — a tag cut without the changelog step cannot silently
ship PR-title-only notes.
The website publishes one post per minor version (v0-18 … v0-22), and
release screenshots live under the matching blog/v0-24/ directory. A patch
release therefore edits the existing post rather than generating a new one, so
--format blog refuses to overwrite unless you pass --force.
Screenshots
pnpm run release:screenshots captures every manifest shot in dark and light
against the built app plus the Xtream mock server — never a real account.
The run is fail-closed: it proves the real ~/.iptvnator/databases directory
(including the SQLite WAL sidecars, checked after Electron exits) was not
touched, launches the app with an allowlisted environment, records and blocks
all non-localhost traffic, scans every frame for external resources and
credential-shaped text, and asserts TMDB enrichment stays disabled. Frames are
staged outside the repository and published only once every shot and every
guard has passed.
Adding a shot for a new feature = one entry in
tools/release/screenshots.manifest.json (plus, if navigation is new, one
named action in tools/release/capture-navigation.ts).
pnpm nx run electron-backend:build-e2e # once, before capturing
pnpm run release:screenshots # all shots, both themes
pnpm run release:screenshots -- --only dashboard --theme dark
pnpm run release:screenshots -- --release v0-24
