 iKeyMon uses [Sparkle](https://sparkle-project.org/) for macOS-safe updates.
 
 1. Generate an EdDSA key pair once (`./Packages/Sparkle/bin/generate_keys`). Store the private key on-disk (for example `~/.config/Sparkle/iKeyMon.key`, which the build script expects) and copy the public key into the `SUPublicEDKey` entry (see Info.plist notes below).
-2. `./scripts/build_release.sh` signs the ZIP with Sparkle’s `sign_update` tool and invokes `generate_appcast` automatically when the Sparkle variables are present. The generated feed is written to `Sparkle/appcast.xml`, so commit that file after every release. Point `SPARKLE_DOWNLOAD_BASE_TEMPLATE` at your release-download prefix (e.g. `https://git.24unix.net/tracer/iKeyMon/releases/download/v{{VERSION}}`) so the generated URLs match where Gitea serves assets. The feed stays inside the repo (it is not uploaded as a release asset).

Set `SPARKLE_DOWNLOAD_BASE_URL` to your release-download root (e.g. `https://git.24unix.net/tracer/iKeyMon/releases/download`) and, if your host groups assets under versioned folders, set `SPARKLE_DOWNLOAD_VERSION_PREFIX` (defaults to `v`, producing URLs like `/download/v26.0.20/...`). The feed stays inside the repo (it is not uploaded as a release asset).
 3. Set `SUFeedURL` in Info.plist (or the corresponding build setting) to the raw URL of `Sparkle/appcast.xml` inside this repo (e.g. `https://git.24unix.net/tracer/iKeyMon/raw/branch/master/Sparkle/appcast.xml`).
 
 Preferences expose Sparkle’s built-in toggles for “Automatically check” and “Automatically download”, and the toolbar button simply calls Sparkle’s “Check for Updates…” sheet.
 
-> `./scripts/build_release.sh` will call `generate_appcast` for you when `SPARKLE_EDDSA_KEY_FILE` and either `SPARKLE_DOWNLOAD_BASE_TEMPLATE` (with `{{VERSION}}` placeholder) or `SPARKLE_DOWNLOAD_BASE_URL` are set. It tries to locate Sparkle’s CLI in DerivedData automatically, but you can override the path via `SPARKLE_GENERATE_APPCAST`. The resulting feed is written to `SPARKLE_APPCAST_OUTPUT` (defaults to `Sparkle/appcast.xml`).
