+## [0.6.3] — 2026-05-30 — Discreet "buy me a coffee" support link
+
+### Added
+- New `RADIO_SUPPORT_URL` constant in `radio.php` (default `https://buymeacoffee.com/davidtkeane`). Wrapped in `if ( ! defined(...) )` so it's override-able from `wp-config.php`.
+- Tiny footer line `☕  Like Radio? If You fancy to buy me a coffee →` inside the **Updates panel** on Settings, below the manual-update note.
+- Matching footer line at the bottom of the **Credits + thanks** card on the About page.
+- Both spots render from the same constant — change one place, both update.
+- **Conditional render**: if `RADIO_SUPPORT_URL` is empty / undefined, the link is silently hidden. Forks can strip funding with one line.
+
+### Design
+- Muted styling deliberate: 12 px, admin-theme-coloured link, subtle top border. Reads as housekeeping ("here's where to send thanks") not a sales pitch. No yellow BMC brand chrome.
+- Dark-theme variant for the divider (`#3c434a`) so it stays subtle on the dark surface.
+
+**Files changed:** `radio.php` (version, `RADIO_SUPPORT_URL` constant), `inc/updater.php` (link inside the Updates panel after the manual-update paragraph), `inc/about.php` (link inside the Credits + thanks card; rotate v0.6.3 into latest expanded slot, v0.6.2 into earlier-releases list), `assets/css/radio.css` (`.radio-support-link` styling + dark-theme override).
