CHANGELOG.md

@@ -7,4 +7,8 @@
 - Added verbose logging in `MainView` to trace server loading, selection, and fetch/ping activity when the list appears empty.
 - Switched `MainView` and `ServerFormView` to the version-aware API client (`APIFactory`/`APIv2_12`) for server summaries and introduced a shared `PingService`.
 - 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.
+- 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.

+Use the helper script to produce distributables in `dist/`:

+```bash

+
+It cleans previous artifacts, builds the `Release` configuration, and drops both `iKeyMon-<version>.zip` and `iKeyMon-<version>.dmg` into the `dist` folder (ignored by git). To enable codesigning + notarization, copy `signing.env.example` to `.signing.env`, fill in your Developer ID identity, Apple ID, team ID, and app-specific password. The script sources that file locally (it remains gitignored) and performs signing/notarization when the values are present.

+# SPARKLE_DOWNLOAD_SUBDIR_TEMPLATE="v{{VERSION}}"
+# SPARKLE_APPCAST_OUTPUT="$ROOT_DIR/Sparkle/appcast.xml"  # default
+```
+
+`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.
+
+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.
+
+### 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. Set `SPARKLE_DOWNLOAD_BASE_URL` to the static portion of your release-download endpoint (e.g. `https://…/releases/download`) and `SPARKLE_DOWNLOAD_SUBDIR_TEMPLATE` to the path segment that should be inserted before each asset (default `v{{VERSION}}` mirrors how Gitea exposes assets). 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`, `SPARKLE_DOWNLOAD_BASE_URL`, and (optionally) `SPARKLE_DOWNLOAD_SUBDIR_TEMPLATE` 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.
+
+### 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).
+
+### Versioning workflow
+
+- The canonical marketing version lives in `version.json` and follows the format `YY.major.minor` (example: `26.1.2`). Update that file manually whenever you cut a new release branch.
+- The build number is derived automatically from the git commit count on the current branch (you can override it by exporting `BUILD_NUMBER` before running the script if needed).
+- Run `./scripts/sync_version.sh` anytime after editing `version.json` (the release script already calls it). The helper updates `MARKETING_VERSION` and `CURRENT_PROJECT_VERSION` inside `iKeyMon.xcodeproj`, keeping Xcode, the app bundle, and release artifacts in sync.
+- `scripts/build_release.sh` reads the same `version.json` for naming the generated ZIP/DMG, so the artifact names, Info.plist values, and UI displays all stay aligned.
