 # Changelog
 
-## Unreleased
+## 26.1.7
+- Added remote reboot support for hosts running KeyHelp API 2.14 or newer.
+- Added a dedicated `APIv2_14` client and mapped 2.14+ hosts to it instead of treating them as API 2.13.
+- Fixed the reboot request to call `/api/v2/server/reboot` with the required JSON confirmation payload.
+- Changed the reboot confirmation and result UI to non-blocking sheets/banner feedback so failures no longer trap the app in modal dialogs.
+- Improved API error messages by surfacing the server response body instead of only generic HTTP status codes.
+- Reduced expected reboot noise by suppressing ping checks for a short grace period after a reboot request.
+
+## 26.1.6
+- Publish Gitea releases as stable by default instead of pre-releases.
+- Update the Homebrew tap automatically after each successful release by rewriting the cask version and DMG checksum, then pushing the tap repo.
+- Simplified the README for end users by adding clear install options and trimming internal release-engineering details.
+- Ignore the local `homebrew-tap/` checkout in the main app repository.
+
+## 26.1.3
+- Fixed version handling for changelogs.
+
+## 26.1.2 (2025-01-03)
+- Synced version.json to 26.1.2.
+
+## 26.1.1 (2025-01-03)
+- Fixed changelog extraction in publish script.
+
+## 26.1.0 (2025-01-03)
+- Auto-populate release description from CHANGELOG when publishing to Gitea.
+
+## Prereleases
+
+### Fixed
+- Fixed excessive refresh timer resets by properly cancelling previous subscriptions and validating value changes before recreating timers.
+- Fixed interval indicator to respect user's refresh interval setting instead of always assuming 60 seconds.
+
+### Added
+- Added status notifications for server monitoring in Preferences → Notifications:
+  - "Status Notifications" toggle: alerts when servers go offline/online or services change status.
+  - "Alert Notifications" toggle: (placeholder for future alert threshold configuration).
+- Ping status changes now trigger notifications (Server Online/Offline).
+- Service status monitoring tracks individual services (DNS, FTP, SSH, HTTP, HTTPS, etc.) and alerts when they go offline or come back online.
+- Notification permissions are requested automatically when the app launches.
+
+### Previous Changes
 - Flattened the project structure so sources live at the repository root instead of the nested `iKeyMon/` folder and updated the Xcode project accordingly.
 - Fixed build settings (entitlements, preview assets) and placeholder previews to work with the new layout.
 - Migrated the updated API layer and unified `ServerInfo` model from the previous branch.
@@ -10,5 +50,5 @@
 - 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.

-### Local release build
-
-Use the helper script to produce distributables in `dist/`:
-
-```bash
-./scripts/build_release.sh
-```
-
-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.
-
-To auto-publish the artifacts as a Gitea release, extend `.signing.env` with:
-
-```
-GITEA_TOKEN="..."
-GITEA_OWNER="tracer"
-GITEA_REPO="iKeyMon"
-# optional: GITEA_API_BASE="https://git.24unix.net/api/v1"
-# optional: GITEA_TARGET_COMMIT="master"
-# optional: GITEA_PRERELEASE="false"   # defaults to true until preferences are done
-# optional Sparkle feed helpers:
-# SPARKLE_EDDSA_KEY_FILE="$HOME/.config/Sparkle/iKeyMon.key"
-# SPARKLE_DOWNLOAD_BASE_TEMPLATE="https://git.24unix.net/tracer/iKeyMon/releases/download/v{{VERSION}}"
-# If you prefer SPARKLE_DOWNLOAD_BASE_URL, it will automatically append `/v<version>` for you.
-# SPARKLE_APPCAST_OUTPUT="$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. 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).
-
-### 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.
