Hello!

As part of our ongoing Equo Chromium improvement cycle, this month’s update is led by Equo Chromium v144.0.1 (Beta), a major step forward for teams embedding modern web UIs into Java desktop applications. It brings meaningful upgrades across CSS/layout capabilities, platform APIs, built-in AI primitives, and security/privacy defaults. We’ll also include a brief roundup of the latest maintenance updates for versions 138 and 128.

Introducing Equo Chromium v144.0.1

UI & Rendering Upgrades (CSS & Layout)

This release expands what you can build on the web side with more powerful native CSS and layout capabilities:

More expressive styling primitives: advanced corner shaping (superellipse / “squircle”), improved typed CSS arithmetic for richer calc() usage, and new capabilities for parameterized styling via custom CSS functions.

Smoother UI transitions: View Transitions enhancements that make complex UI motion and state changes easier to implement cleanly.

Typography improvements: stronger @font-face controls for modern font features and variation settings.

Platform APIs that Improve Real Applications Workflows

A few additions stand out as particularly useful in desktop-embedded contexts:

Temporal API for modern, safer date/time handling (a long-awaited upgrade over legacy patterns).

Better data access in IndexedDB with getAllRecords() for efficient bulk reads.

On-device speech recognition through the Web Speech API, enabling voice-driven workflows without depending on external services by default (depending on platform support).

WebGPU compatibility mode, improving support on older hardware, and expanding the range of environments where GPU-powered features can run reliably.

Built-in AI APIs (new primitives)

v144 introduces built-in APIs intended to make AI features easier to ship and standardize:

Prompt API for AI-powered experiences.

Writer / Rewriter / Proofreader APIs for assisted text generation and correction.

Plus additional language tools (summarization/translation/language detection) available in stable.

Security & Privacy Improvements

v144 strengthens defaults and reduces common privacy exposure:

Local Network Access restrictions with explicit permission prompts.

Post-quantum cryptography for WebRTC connections.

Reduced Accept-Language header to mitigate fingerprinting.

window.name isolation across browsing context groups for stronger cross-context safety.

Important Changes to Note

This release also includes changes that may affect upgrade planning:

Manifest V2 extensions are no longer supported.

Support for legacy operating systems/platforms has been removed.

Updated minimum platform requirements.

Ongoing updates on Supported Branches (v138 & v128)

Alongside the v144 Beta, we’ve continued delivering stability improvements and API enhancements on the 138 and 128 lines.

Across both branches, recent updates include:

Expanded Subscribe API coverage, adding new browser events (console, navigation, title, file, clipboard, and load lifecycle events).

Download workflow improvements, including before-download and download-update events, plus Drag & Drop support.

Client-side decoration support and related JS API methods (v128).

Improved proxy and authentication handling, including runtime proxy updates and optional authentication dialog suppression.

Multi-instance stability fixes, preventing crashes when sharing cache_path.

Better SWT/Eclipse compatibility, including restart stability improvements and scaling fixes on Windows.

GTK4 support and Wayland rendering fixes on Linux.

These updates continue to refine the integration's reliability for production deployments on long-term supported branches.
