 - Detection now probes `meta.api_version` so future API versions are selected automatically, and the ping loop logs only failures to keep output quiet.
 - Introduced repository-wide version management via `version.json` + `scripts/sync_version.sh`, ensuring Xcode targets and release artifacts stay aligned.
 - Enhanced `scripts/build_release.sh` to timestamp/harden signatures, notarize DMGs, and optionally publish tagged releases (pre-release by default) with ZIP/DMG assets directly to Gitea when credentials are configured.
-- Added a lightweight update checker that polls the latest Gitea release, surfaces alerts + download shortcuts, and exposes new toggles (auto-check + prerelease channel) inside Preferences.
+- Integrated Sparkle (via Swift Package Manager) to handle automatic update checks, downloads, signature verification, and relaunches, replacing the previous custom updater UI. Preferences now simply surface Sparkle's check/download toggles.
+- `scripts/build_release.sh` can optionally run Sparkle’s `generate_appcast` (when signing key and download prefix env vars are set), producing a ready-to-host `appcast.xml` alongside the ZIP/DMG artifacts.
 - Further reduced MainView console noise by removing redundant refresh/onAppear logs.

 `GITEA_TARGET_COMMIT` defaults to the current `HEAD` commit, so overriding it lets you publish from another branch if needed. Whenever those variables are set, the script will create (or reuse) tag `v<version>` and upload both ZIP and DMG as release assets automatically.
 
-### Update checks
+If you re-run the release script for the same version, it removes any existing assets with the same filenames before uploading, so you never end up with duplicate ZIP/DMG files on the release page.
 
-- The app can automatically query the Gitea release feed on launch (Preferences → Updates → “Automatically check for updates”).
-- “Check for updates” also lives in the main window toolbar; if you're already up to date, you'll get a confirmation alert.
-- Preferences let you opt into prerelease builds (enabled by default for now because current releases are flagged prerelease) and show the latest fetched release number for reference.
-- When a newer build is available, a prompt offers to open the DMG download (or you can revisit the release info inside Preferences).
+### Sparkle updates
+
+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 already match Gitea’s asset paths. 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 `SPARKLE_DOWNLOAD_BASE_TEMPLATE` (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`).
+
+> Build settings include `INFOPLIST_KEY_SUFeedURL` and `INFOPLIST_KEY_SUPublicEDKey`. Make sure to fill both before shipping a build so Sparkle knows where to fetch updates and how to verify them.
+
+#### Debugging Sparkle updates
+
+Launch the shipped app via CLI with `SPARKLE_VERBOSE_LOGGING=1` to mirror Sparkle’s activity in stdout/stderr:
+
+```bash
+SPARKLE_VERBOSE_LOGGING=1 /Applications/iKeyMon.app/Contents/MacOS/iKeyMon
+```
+
+Sparkle’s installer helper runs in a separate `SUPipedBinary` process. If the installer fails, collect additional details with `log show --process SUPipedBinary --last 5m`.
+
+### Automated release push
+
+If you want `git push origin master` to build/sign/notarize/upload automatically, enable the provided pre-push hook:
+
+```bash
+git config core.hooksPath hooks
+```
+
+The hook (see `hooks/pre-push`) watches for pushes that include `refs/heads/master`, automatically bumps `marketing_version` (incrementing the last component), runs `scripts/build_release.sh`, stages `version.json`, `iKeyMon.xcodeproj/project.pbxproj`, and `Sparkle/appcast.xml`, then creates a commit `chore: release <version>`. It performs its own `git push` behind the scenes and cancels the original push command so you don't upload the same refs twice—once you see “Release … pushed. Original push cancelled”, you're done (Git will report the original push failed; that's expected). To skip the automation temporarily, prepend `SKIP_RELEASE=1` to your `git push` command.
+
+The bumping logic lives in `scripts/bump_version.sh` (feel free to run it manually if you need to create a release without pushing).
