## Tauri v2.12.5 tidies up the installer

Tauri is an open-source framework for building desktop apps. The screens are web technology (HTML, CSS, JavaScript) and the core is written in Rust. Its JavaScript API package, `@tauri-apps/api`, has 2,744,435 weekly downloads on npm.

[tauri v2.12.5](https://github.com/tauri-apps/tauri/releases/tag/tauri-v2.12.5) came out on October 21. There is no headline feature. What it does fix is the NSIS installer that Tauri uses to build Windows setup files, and [CLI v2.12.4](https://github.com/tauri-apps/tauri/releases/tag/%40tauri-apps%2Fcli-v2.12.4) shipped the same day. Once you open the notes, these are pretty practical fixes for anyone who ships an app.

## The Windows installer now blocks downgrades

v2.12.5 fixes two bugs.

- The installer language string `choowHowToInstall` was a typo and is now `chooseHowToInstall`. Custom language files that define only the old name still work for now, but the notes tell you to move to the new one (#16333)
- When `bundle.windows.allowDowngrades` is `false`, an installer no longer lets an older version overwrite a newer one that was installed from an MSI. This covers silent (`/S`), passive (`/P`) and update (`/UPDATE`) modes too (#16254)

A typo fix sounds trivial. It is not, if you maintain your own language files: you now have a rename to make.

## The CLI has fewer false alarms

`@tauri-apps/cli` v2.12.4 contains this fix. If `rustup` is on the PATH but no toolchain is installed, `rustup target list` fails, and the CLI now skips its `--target` check instead of rejecting every target as missing (#16305).

The same CLI release raises `zip` to v9 in answer to the security advisories RUSTSEC-2026-0367, 0368 and 0369 (#16317). The notes do not say how far those advisories actually reached Tauri apps.

**Dependencies that v2.12.5 updated**

- tauri-build v2.7.4 → tauri v2.12.5
- tauri-macros v2.7.4 → tauri v2.12.5
- tauri-runtime-wry v2.12.3 → tauri v2.12.5

## v3.0.0-alpha.5 is still quiet

[tauri v3.0.0-alpha.5](https://github.com/tauri-apps/tauri/releases/tag/tauri-v3.0.0-alpha.5) was published on October 14. The only change in its notes is a dependency update that moves `tauri-utils`, `tauri-runtime`, `tauri-macros` and `tauri-build` to 3.0.0-alpha.4. The notes show no new feature and no breaking change.

The road to v3 is still at the alpha stage. This week's record gave me no reason to move yet.

## View

If you ship Windows installers yourself, I would open the `allowDowngrades` setting first. A deployment script that reinstalled an older version in silent mode could now be stopped. The notes describe the behavior when the setting is `false` and nothing more, so the rest is yours to check.

The CLI fix is not urgent, honestly. It only bites on a developer machine where `rustup` is half set up.

The three security advisories do bother me a little. The notes give the advisory numbers and not their reach. I don't know that part yet.
