 All notable changes to the Piperless WordPress plugin.
 
+## [1.1.4] — 2026-05-12
+
+### Added
+
+- **Dashboard widget** — new "Piperless — Audio Storage" widget on the WordPress admin dashboard (togglable via Screen Options). Shows Opus/MP3/WAV file counts and total sizes in a card grid, published posts without audio transcripts with a quick "View posts" link, and server disk usage with a horizontal usage bar and percentage indicator.
+
+### Changed
+
+- **About tab** — SVG icons now appear inline before the GitHub Repository and Buy Me a Coffee links for a polished look.
+
+### Fixed
+
+- **Dashboard TypeError** — `human_size()` parameter changed from `int` to `float` to handle `disk_free_space()` return type.
+
 ## [1.1.3] — 2026-05-11

 - **Smart text extraction** — uses the post excerpt when available to avoid reading embedded content (YouTube, Twitter, third-party embeds), decimal numbers, and other artifacts that produce garbled speech. Falls back to the full post body when no excerpt is set.
 - **No external services** — Piper runs on your server. Text never leaves your infrastructure. GDPR-compliant by architecture.
 - **Production-hardened** — 29/29 security audit clearance. Rate limiting, authorization layering, process timeout guards, open_basedir aware.
+- **Dashboard widget** — at-a-glance storage stats on the WordPress dashboard (togglable via Screen Options). File counts and sizes by audio format, posts awaiting transcription, and disk usage bar.
 - **8 admin languages** — Dutch, German, French, Spanish, Chinese (Simplified), Japanese, Brazilian Portuguese, and Italian translations included.
