Tauri 2.12 is here! This is the biggest update so far in the 2.x releases.

Dropping official Windows 7 support

With the latest WebView2 installer no longer running on Windows 7 (crashes with no entry point for GetPackagesByPackageFamily), we finally decided it’s time to drop Windows 7 support.

This will allow us to raise the MSRV to unblock many dependency updates which has been stalled to stay on 1.77 (the last rust version with built-in Windows 7 support - released March 2024!¹) as was planned when Tauri v2 was initially released.

We know many people will be sad about this news and we apologize for that, but at some point we simply have to accept defeat.

More on this, see https://github.com/tauri-apps/tauri/issues/12550

Minimum Supported Rust Version (MSRV) policy

We have raised the MSRV to 1.90.

As discussed in https://github.com/tauri-apps/tauri/issues/15579, we settled our policy on

(stable - 3)

stable is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.

We only update the MSRV in minor or major releases.

New features

Permission request handler

You can now use on_permission_request to allow/deny webview permission requests:

use tauri::{
  webview::{PermissionKind, PermissionResponse, WebviewWindowBuilder},
  WebviewUrl,
};
tauri::Builder::default()
  .setup(|app| {
    WebviewWindowBuilder::new(app, "main", WebviewUrl::App("index.html".into()))
      .on_permission_request(|_, kind| match kind {
        PermissionKind::Geolocation => PermissionResponse::Allow,
        PermissionKind::Notifications => PermissionResponse::Allow,
        _ => PermissionResponse::Default,
      })
      .build()?;
    Ok(())
  });

Notable changes

• On mobile, loading the page through dev web servers should be much faster.

Explicit Resource Management for Resource

We have added Explicit Resource Management to Resource. You can now use the using syntax in supported browsers or with polyfills:

import { create, BaseDirectory } from "@tauri-apps/plugin-fs"
...
{
  await using file = await create("foo/bar.txt", { baseDir: BaseDirectory.AppConfig });
  await file.write(new TextEncoder().encode("Hello world"));
  // Before `file` goes out of scope, it is disposed by calling `file[Symbol.asyncDispose]()` and awaited.
}

To support older browsers, add the following to the globals (e.g. adding to the HTML file):

Symbol.asyncDispose ??= Symbol('Symbol.asyncDispose');

And for the compiler, for example tsc, rollup, vite, add the following to tsconfig.json:

{
  "compilerOptions": {
    "target": "es2022",
    "lib": ["es2022", "esnext.disposable", "dom"]
  }
}

Android

• $VIDEO and video_dir() were broken before resolving to external cache storage. It’s now fixed to resolve to the app-specific Movies directory instead.

  IMPORTANT: Files previously written to the old location (.../cache) will not be discovered at the new location (.../files/Movies). Migrate existing files or update path assumptions accordingly.

• Updated tauri android init template to use Gradle v9 and Kotlin v2, this will allow you to use the latest Java (v25) that is now shipped with Android Studio by default.

• Updated tauri android init template targetSdk from 36 to 37 (Android 17).

• Migrated the Gradle scripts from the deprecated kotlinOptions DSL to compilerOptions, which is accepted by both Kotlin Gradle Plugin 1.9.x and 2.x. This lets projects move to Kotlin 2.x without hitting the hard error that 2.3+ raises on the old DSL. This increased the minimum supported Gradle version to 8.13, if your gradle is on an earlier version, delete src-tauri/gen/android/gradle/wrapper/gradle-wrapper.properties and re-run tauri android init to update it.

• Fixed missing consumer-rules.pro file in the template.

  IMPORTANT: For plugin authors, update your build.gradle.kts file to remove the

      buildTypes {
          release {
              isMinifyEnabled = false
              proguardFiles(
                  getDefaultProguardFile("proguard-android-optimize.txt"),
                  "proguard-rules.pro"
              )
          }
      }

  section and rename your proguard-rules.pro to consumer-rules.pro to match the consumerProguardFiles("consumer-rules.pro") in the template.
