Upgrading?
AI Summary
The v3 alpha of Tauri utilities introduces a significant performance improvement to the ACL (Access Control List) system and changes how resources are resolved at runtime, eliminating the need to copy them to the target directory during build.
Key Highlights
- Resources now resolved from source paths at runtime instead of copying to the cargo target directory.
- Reduced ACL size by storing autogenerated command permissions as a `commands` list.
- Autogenerated permissions now written to `OUT_DIR` instead of the crate's folder.
- MSRV updated to Rust 1.95.
Breaking Changes
- `tauri-build` no longer copies configured resources to the cargo target directory.
- Plugin and app build scripts now write autogenerated permissions to `OUT_DIR` instead of the crate's `permissions/autogenerated` folder.
New Features
- Added `tauri_utils::acl::build::collect_permission_files` and `define_permissions_from_files` for merging permission files.
- Application manifest gains implicit `allow-*` and `deny-*` permissions.

## [3.0.0-alpha.0]
### New Features
- [`364a0e711`](https://www.github.com/tauri-apps/tauri/commit/364a0e711d8c1e5f2ad9439feff498055f5065c7) ([#15882](https://www.github.com/tauri-apps/tauri/pull/15882)) `tauri-build` no longer copies the configured resources to the cargo target directory; on desktop, unbundled apps (`tauri dev` / `cargo run`) now resolve resources at runtime from their source paths instead. This means editing a resource file no longer triggers a full application rebuild, and changes to plain relative resources are picked up live by the running app.
- When all configured resources are plain relative paths (e.g. `"assets/*"`), the resource directory resolves to the directory containing `tauri.conf.json` and files are read directly from the sources.
- When resources are remapped (map notation, `../` or absolute paths), the bundle layout is mirrored next to the executable on the first resource directory access of each run.
The `bundle > resources` configuration is now part of the config embedded by `generate_context!`, where it was previously stripped.
### Enhancements
- [`65792f536`](https://www.github.com/tauri-apps/tauri/commit/65792f5364e34daaaf8cd612452f6dc0bc63a2bd) Plugin and app build scripts now write the autogenerated command permissions to `OUT_DIR` instead of the crate's `permissions/autogenerated` folder, so they no longer need to be committed at the crate level. This applies to plugin crates (`tauri-plugin`) and the application manifest (`tauri_build::AppManifest`); inlined plugins (`tauri_build::InlinedPlugin`) already wrote them to `OUT_DIR`. For plugin crates, the human-readable permission documentation (`reference.md`) is still generated in `permissions/autogenerated` so it stays recoverable.
Added `tauri_utils::acl::build::collect_permission_files` and `tauri_utils::acl::build::define_permissions_from_files` to allow merging permission files from multiple directories into a single permission file list.
### Performance Improvements
- [`fb7bdd95b`](https://www.github.com/tauri-apps/tauri/commit/fb7bdd95be319d70a1097d285bb7b170562339f2) Reduce the size of the resolved ACL embedded in the app by storing the autogenerated command permissions as a `commands` list on the plugin/app manifest instead of two explicit permissions (`allow-$command` and `deny-$command`) per command. The `allow-$command`/`deny-$command` permissions are now materialized on demand when resolving the ACL.
The application manifest also gains implicit `allow-*` and `deny-*` permissions that allow or deny **all** of its commands through a single resolved entry, so capabilities no longer need to list every command individually.
### What's Changed
- [`c9277f3c0`](https://www.github.com/tauri-apps/tauri/commit/c9277f3c0c24518a7ab7d7d1f2489e004b1597f7) Set MSRV to 1.95.
- [`19929799f`](https://www.github.com/tauri-apps/tauri/commit/19929799f42398a6e85adb00ae02f2e7fe46d214) First v3 alpha release!
