Tauri v3.0.0-alpha.6 fixes window event race conditions and updates runtime

The Tauri project has released version 3.0.0-alpha.6, an incremental update to its Rust-based desktop and mobile application framework. This release focuses on stabilizing the event loop and fixing race conditions related to window and webview lifecycle management.

Developers using the Tauri framework will benefit from improved reliability when handling window creation and destruction. The update also includes a dependency bump to tauri-runtime version 3.0.0-alpha.5 to maintain compatibility within the v3 alpha development cycle.

Lifecycle and Event Loop Improvements

• Event Listener Management: Tauri now manages per-window and per-webview event listeners internally, feeding them directly from the run event loop to prevent missed events during the registration phase.
• Webview Lifecycle Fix: Resolved a bug where calling Webview::close on a handle to an already closed webview could inadvertently tear down the state and listeners of a new webview sharing the same label.
• Window Recreation Stability: Fixed an issue where recreating a window with an existing label while the previous instance was still being destroyed resulted in the loss of registered event listeners.
• Dependency Update: The release upgrades the core dependency to tauri-runtime@3.0.0-alpha.5.

Why it matters

These fixes are critical for software engineers building complex multi-window desktop applications where rapid window creation and destruction occur. By ensuring event listeners are correctly attached and not leaked or overwritten, Tauri improves the overall stability of the cross-platform runtime.
