Plain <a target="_blank"> is a no-op inside the Tauri webview, so the "view release notes" button in Settings did nothing. Add a small open_url command that hands http(s) URLs to the OS opener (macOS open / Windows rundll32 / Linux xdg-open) — the same mechanism the installer launcher already uses — and wire the button through it.
fix(ui): 「查看日志」按钮无法跳转 Release 页面
Previously macOS updates ended by opening the downloaded dmg, leaving the user to drag the .app into /Applications and confirm Finder's replace prompt. Now, when running from a real .app bundle, the updater mounts the dmg read-only and spawns a trampoline shell script before exiting. The trampoline waits for the process to die, stages the new bundle next to the target with ditto, swaps with atomic mv (rolling back if the second move fails), detaches, and relaunches — zero prompts. Any failure (dev binary outside a bundle, hdiutil errors, unwritable install dir) falls back to the old open-the-dmg flow. Pure helpers (bundle-path detection, hdiutil mount-point parsing, shell quoting, script rendering) are unit-tested cross-platform; the hdiutil/ditto execution is cfg(macos)-gated. Swap mechanics validated end-to-end against the signed V1.4.1 dmg in a sandboxed target, and the full GUI flow verified on hardware: check -> download -> install -> automatic relaunch into the official signed build.

Release v1.4.2
Patch 发版，两项均已实测验证：
target="_blank"，改走系统 opener）四件套已对齐 1.4.2。
Note
Medium Risk
macOS in-place updates perform filesystem bundle swaps and shell execution; failures fall back to the manual DMG flow, but a bad edge case could still affect the installed app.
Overview
v1.4.2 bumps version metadata across the frontend, Tauri crate,
tauri.conf.json, andversion.json.Release notes in settings no longer use a
target="_blank"link (which the webview ignores). View release notes calls a new Tauriopen_urlcommand that openshttp/httpsURLs via the OS browser (open/xdg-open/rundll32), with scheme validation and unit tests.macOS updates change
launch_installer_and_exit: when the app runs from a real.appbundle, it mounts the downloaded DMG, writes a detached trampoline shell script, exits, and the script waits for the process, stages the new bundle withditto, atomically swaps.appfolders with rollback, detaches the volume, and relaunches. If in-place prep fails (dev build, mount errors, etc.), behavior falls back to opening the DMG for manual install. Windows/Linux install launching is unchanged aside from routing throughlaunch_inner.Reviewed by Cursor Bugbot for commit 6a060c5. Bugbot is set up for automated code reviews on this repo.
