+## [0.7.0] — 2026-05-30 — WordPress.org submission prep (full Plugin Check clean)
+
+Ran the official WordPress.org **Plugin Check (PCP)** against v0.6.3 — surfaced **169 issues**. This release closes all of them so the plugin is submission-ready for the WordPress.org plugin directory.
+
+### Changed — branding
+- **Plugin Name renamed: "Radio" → "RangerHQ Radio"** to (a) remove the trademarked term "SomaFM" from the plugin name surface (PCP `trademarked_term` warning) and (b) line up with the RangerHQ plugin family. SomaFM is still credited in the Description and on the About page as the data source. Plugin folder/slug stays `a-radio` — no install path changes; existing user_meta keys (`radio_state` / `radio_history` / `radio_favourites`) untouched.
+- **`Text Domain` header renamed**: `radio` → `a-radio` (matched the slug for the first time; PCP `textdomain_mismatch`).
+- **`Requires at least` bumped**: `5.0` → `5.3` (matches `wp_date()` usage in `inc/history.php`; PCP `wp_function_not_compatible_with_requires_wp`).
+- **File docstring header** dropped "SomaFM" from the prominent first line.
+
+### Changed — code (mass-mechanical)
+- **134 i18n call sites** rewritten from `'radio'` text domain → `'a-radio'` across `radio.php`, `inc/admin-page.php`, `inc/dashboard-widget.php`, `inc/settings.php`, `inc/about.php`, `inc/history.php`, `inc/updater.php`. Single sed pass on the unique pattern `, 'radio' )` (the 6 menu-slug `'radio'` references in `add_menu_page` / `add_submenu_page` were left alone — they're the URL slug, not the text domain).
+
+### Fixed — security
+- **8 × `MissingUnslash` + 8 × `InputNotSanitized`** in the v0.5.0 history endpoints (`radio_ajax_log_track`, `radio_ajax_toggle_favourite`). All four `$_POST['artist|title|station|station_id']` access points are now wrapped `sanitize_text_field( wp_unslash( $_POST['…'] ) )` (or `sanitize_key()` for `station_id`) at the access point. The downstream `radio_sanitize_entry()` helper still re-sanitizes as belt+braces.
+
+### Added — translator comments
+- 6 × `printf` / `sprintf` calls with placeholders now carry `/* translators: ... */` comments: pop-out window title, updater status messages (HTTP error / available / up-to-date / download), history page "%s ago" relative time.
+
+### Refactored — pop-out window
+- Inline `<link>` stylesheets, inline `<style>` block, and `<script>` tag in `radio_render_popout_page()` replaced with `wp_enqueue_style()` + `wp_enqueue_script()` + `wp_localize_script()` registered before the HTML output, then `wp_print_styles()` in `<head>` and `wp_print_footer_scripts()` at end of `<body>`.
+- Popup-specific CSS (header, close button, wrap, layout overrides, popup dark theme) moved out of the inline `<style>` and into `assets/css/radio.css` under `body.radio-popout` scope so it only fires inside the popup.
+
+### Removed
+- `.DS_Store` files (root + `assets/`) — stray macOS Finder artefacts; PCP `hidden_files`. `.gitignore` already covers them.
+
+### Added — distribution
+- **`readme.txt`** in proper WordPress.org format: Plugin headers, Contributors, Donate link, Tags, Requires-at-least, Tested-up-to, Stable Tag, Requires-PHP, License, License URI, short description (≤150 chars), Description, Installation, FAQ, Screenshots, Changelog, Upgrade Notice.
+
+### Compat notes
+- No behaviour change for existing users. Per-user state (`radio_state` / `radio_history` / `radio_favourites`) is preserved across the upgrade — no migration needed.
+- The displayed Plugin Name in **Plugins → Installed** changes from "Radio" to "RangerHQ Radio" — that's the only visible difference on update.
+
+**Files changed:** `radio.php` (header + 6 translator comments + 8 $_POST hardenings + popup enqueue refactor), `inc/admin-page.php` / `inc/dashboard-widget.php` / `inc/settings.php` / `inc/about.php` / `inc/history.php` / `inc/updater.php` (textdomain mass-fix + translator comments where applicable + about-page version rotation), `assets/css/radio.css` (popup styles moved in under `body.radio-popout`), **new** `readme.txt`, **removed** `.DS_Store`, `assets/.DS_Store`.

+A small, focused internet radio player for your WordPress admin — 44 hand-curated stations, history, favourites, and a pop-out window.
+
+== Description ==
+
+**RangerHQ Radio** adds a tiny, focused internet radio player to your WordPress dashboard so you can have background music while you work in the admin — without leaving the page, opening Spotify, or installing a desktop client.
+
+= What you get =
+
+* **44 hand-curated stations from [SomaFM](https://somafm.com)** across 10 genres — ambient, electronic, lounge, rock, metal, jazz, world, reggae, holiday and specials. From coding-focus ambient (Groove Salad, Drone Zone) to drive-time electronic (DEF CON Radio, Beat Blender) to mellow lounge (Lush, Secret Agent).
+* **Now-playing indicator** — small CSS dancing-bars equalizer that pulses while audio is playing. A Web Audio frequency visualizer kicks in automatically when the browser allows it (with a graceful fallback to the CSS bars).
+* **Track history + favourites** — every track that scrolls past is logged to your personal History page (capped at 500); a star toggle promotes the good ones to a separate Favourites tab that doesn't age out. Each row has four search links (Spotify, YouTube, Apple Music, Bandcamp) so you can find that track on whichever service you use.
+* **Pop-out mini-player** — a 380×560 standalone window that persists across the main tab's navigation, so background music doesn't cut when you move between Plugins, Posts, Users, etc.
+* **OS media keys** — F8/headphone buttons/lock-screen widget play and pause the radio (via MediaSession API).
+* **Mute toggle** — the speaker icon is clickable; remembers prior volume.
+* **Dark theme** — explicit dark option for the player surface (`Settings → Theme`).
+* **Per-user state** — your chosen station, volume, theme, history, and favourites all live in `user_meta`, so each WordPress user has their own setup.
+
+= Privacy + dependencies =
+
+* **No tracking, no telemetry, no third-party scripts on your admin pages.** Audio plays directly in your browser via HTML5 — just an `<audio>` element pointed at SomaFM's public streams.
+* **No data leaves your site.** History and favourites are stored in your own `wp_usermeta`. The four search links use deep-link search URLs on each provider's public site — no API keys, no third-party JS embedded.
+* **Stations courtesy of [SomaFM](https://somafm.com)** — an independent, listener-supported, commercial-free internet radio network broadcasting from San Francisco since 2000. RangerHQ Radio is a small wrapper around their public streams. If you enjoy the music, please consider [supporting SomaFM directly](https://somafm.com/support/).
+
+== Installation ==
+
+1. Upload the plugin folder to `/wp-content/plugins/` (or install from the WordPress plugin directory).
+2. Activate the plugin through the **Plugins** menu in WordPress.
+3. Open **Radio → My Radio** in the admin sidebar and press Play. Your station and volume choice are saved per user.
+
+There is no separate configuration step — defaults are sensible (Groove Salad at 60% volume). Settings are at **Radio → Settings**.
+
+== Frequently Asked Questions ==
+
+= Does this work on the front-end of my site? =
+
+No — RangerHQ Radio is admin-only. It adds a player to the WordPress dashboard for you (and your other authenticated admins) to use while working. It does not embed a radio player on the public-facing site.
+
+= Can I add my own stations? =
+
+Not via the admin yet. The station list is hard-coded in `inc/stations.php` (44 SomaFM stations). If you'd like to add custom stations or other internet radio sources, please open an issue on the [Gitea repo](https://git.davidtkeane.com/ranger/a-radio).
+
+= The pop-out window doesn't open. =
+
+Your browser may be blocking pop-ups. Click the address bar's pop-up icon to allow pop-ups for this site, then try again.
+
+= Why does Touch ID / a passkey prompt appear when I press Play? =
+
+It shouldn't. This plugin uses no biometrics or authentication of its own — that's a different plugin in the RangerHQ family.
+
+= The current-track display says nothing / is hidden. =
+
+SomaFM's track-info endpoint (`somafm.com/songs/{station}.json`) is fetched best-effort. If it's unreachable or the browser blocks the request, the track display silently hides. The player keeps working regardless.
+
+== Screenshots ==
+
+1. The main player page (Radio → My Radio) with the now-playing indicator dancing while audio is playing.
+2. The dashboard widget — same player, compact, sits alongside your usual dashboard widgets.
+3. Track History page with star-to-favourite and four search-provider links per row.
+4. Pop-out mini-player window — keeps playing while you navigate the rest of the admin.
+
+== Changelog ==
+
+= 0.7.0 =
+* WordPress.org submission prep — full PCP-clean. Plugin name normalised to **RangerHQ Radio** (SomaFM stays in the description as the data source). Text Domain renamed `radio` → `a-radio` everywhere (134 i18n call sites updated). Six `printf` / `sprintf` calls now carry translator comments. All admin `$_POST` access now `wp_unslash()` + `sanitize_*` at the access point. `Requires at least` bumped to 5.3 (matches `wp_date()` usage). Pop-out window now uses `wp_enqueue_*` + `wp_print_styles()` / `wp_print_footer_scripts()` instead of raw `<link>` / `<script>` tags; popup-specific CSS moved into `radio.css` under `body.radio-popout` scope. `.DS_Store` files removed. Proper `readme.txt`.
+
+= 0.6.3 =
+* Discreet "buy me a coffee" support link in the Updates panel and the About-page Credits card. Single `RADIO_SUPPORT_URL` constant; conditional render — silently hidden if the constant is empty.
+
+= 0.6.2 =
+* Current version badge on the Settings page — small grey pill follows the H1 reading `v{RADIO_VERSION}`.
+
+= 0.6.1 =
+* About page restructure — 3-card top row (What / Who / Credits) + full-width Version history with the latest expanded and earlier releases as one-liners.
+
+= 0.6.0 =
+* Pop-out mini-player. `↗ Pop out` button beside Play opens a 380×560 standalone window that persists across the main tab's navigation, so background music keeps playing while you click around Plugins / Posts / Users.
