New UI Releases: Slint 1.3, Flutter 3.16, Rust 1.74, Notion AI, Linux Kernel

Slint 1.3 released

Slint 1.3 adds Android support, offering a Rust‑based UI for experimentation (not production‑ready). Slint is a GUI toolkit for Rust, C++ or JavaScript, now using a default style that mimics Windows Fluent and macOS Cupertino, both implemented in pure Slint code.

It also integrates Node.js via the napi‑rs crate, making the UI compatible with the latest Node.js versions and allowing integration into the Node.js event loop. Developers looking for a lightweight Electron alternative can consider Slint.

Flutter 3.16 stable released

Flutter 3.16 introduces an Android preview of the Impeller rendering engine, built on Vulkan, and includes Dart 3.2. Impeller aims for high‑performance, cross‑platform UI but may perform poorly on devices without Vulkan support; an OpenGL backend is planned.

The Material 3 component library is now the default, with Material 2 slated for removal. Some widgets have not yet been updated, so developers may need to manually migrate UI components.

Flutter’s casual‑game toolkit also received a major update, providing templates and resources to boost game development efficiency.

Rust 1.74 released

Rust 1.74.0 brings stable features such as Cargo lint configuration and registry authentication, including credential providers for OS‑specific secret stores and custom token handling. The release can be installed via: rustup update stable Notion adds AI‑driven Q&A

Notion launched a beta Q&A feature that uses AI to answer queries in a wiki‑style knowledge base. It is not a chatbot; answers are generated by AI and linked to relevant Notion pages. The feature is included for all Notion AI subscribers, with early access via a waitlist.

Linux kernel series 6.6, 6.5, 6.1, 5.15, 5.10, 5.4, 4.19, 4.14 released

The new kernels fix multiple bugs, including a vulnerability that could allow unauthorized privilege escalation. Users can download the sources from the official Git repository or kernel.org.
