Guidonica 2026.10.1

Send an exercise as a link, discover hidden features through short tips, and open Guidonica in your language at guidonica.it/it/, /fr/, /de/ and /es/.

Added

• The About dialog and footer link to Guidonica on Bluesky and Mastodon (ADR 0082).
• The About dialog and footer link to Guidonica on Instagram too, where you can watch the trailer (ADR 0084).
• Send an exercise as a link: Settings → Practice → Share copies a link with your clef, meter, tempo, note values and notes, and whoever opens it practises with the same settings (ADR 0085).
• Guidonica has an address in each language: guidonica.it/it/, /fr/, /de/ and /es/ open in Italian, French, German and Spanish, so searches in those languages can find it (ADR 0086).
• A short tip when you open Guidonica points to features you may have missed, such as level presets, note names and exercise links, and now and then to our social pages and Ko-fi. Turn tips off in Settings → Practice. (ADR 0087)
• A privacy policy, in English and Italian, linked from the About dialog and the footer (ADR 0088).

Changed

• The About dialog's privacy line now says your settings stay on your device. Visiting the site still reaches its host, GitHub Pages, as the privacy policy explains (ADR 0088).

Fixed

• In Instagram, Facebook and Threads, which can't rotate, the landscape tip now explains how to open Guidonica in your browser instead (ADR 0083).
• The What's new and About buttons no longer overflow the dialog on narrow phones; long labels wrap instead.

Internal

• Profile banners for Mastodon, Bluesky, X and YouTube, generated by pnpm banners (ADR 0079).
• rel="me" links to the Mastodon and Bluesky profiles in index.html, and the @guidonica.it Bluesky domain handle (ADR 0080).
• Releases are announced on Bluesky and Mastodon by CI, as a thread opened by a > headline in the changelog (ADR 0081).
• README, SPEC, AGENTS and contributor docs brought up to date with the current app, and the 16:9 trailer embedded in the README. The AGENTS clock and buffer rules now describe the scheduler's wake-up timer and the beat-based lookahead.
• Pre-release privacy, security and legal audit: a private address was removed from ADR 0074 and from history with a second history rewrite, source-map-js was bumped to 1.2.2 for a dev-only advisory, and tests now reject any non-public guidonica.it address (ADR 0088).
