 A dated build may carry SemVer build metadata in the synchronized application

+version, for example `2.0.0-Beta.2+build.20260924`. Keep its release tag in the existing

+public Beta still increments `N`. Use the `build.` prefix for date metadata:
+Tauri 2.10.1 otherwise maps a numeric date to the fourth Windows product-version
+component, which is a 16-bit field. The full version still appears in the app and
+updater manifest; NSIS uses its supported numeric fallback for file metadata.
+See [the pinned NSIS bundler](https://github.com/tauri-apps/tauri/blob/tauri-cli-v2.10.1/crates/tauri-bundler/src/bundle/windows/nsis/mod.rs#L149).
 
 These tags publish the macOS, Windows, and Android Tauri hosts. Linux is not part of the Tauri matrix. Its independent host is built by `.github/workflows/release-linux-egui.yml`, which accepts an existing `release_tag` and writes `latest-linux-egui-x86_64.json`. This workflow has no automatic tag trigger; Linux publication requires its own product acceptance below.
