What’s New in Safari Technology Preview 196?
This latest release of Safari Technology Preview brings a plethora of improvements and bug fixes across various areas, including Canvas, CSS, JavaScript, Web API, Web Inspector, WebGL, and WebRTC. Let’s delve into some of the notable changes:
Canvas Enhancements
- Visibility Toggling Fix: A longstanding issue where toggling the visibility of a canvas parent would undo the effect of clearRect has been resolved, ensuring consistent rendering behavior.
- Image Exception Handling: The drawImage API now properly throws an exception when the image being drawn is in a broken state. Improving error handling and providing developers with better feedback.
Web API Advancements
- Blob and PushMessageData Support: The introduction of bytes() support for Blob and PushMessageData objects empowers developers to work more efficiently with binary data. Enabling advanced use cases such as file transfers and real-time communication.
CSS and Web Inspector Improvements
- Fuzzy Search Code Completion: The CSS source editor now supports fuzzy search code completion. Enhancing developer productivity by providing intelligent and intuitive suggestions as they write CSS code.
- Underscore Array Variable Handling: A bug that prevented the compilation of shaders containing array variables starting with an underscore has been fixed. Ensuring compatibility with a wider range of WebGL applications.
Real-Time Communication Enhancements
- Reduced getUserMedia Delay: Safari Technology Preview 196 addresses a delay in the resolution of the getUserMedia promise. Improving the performance and responsiveness of real-time communication applications that rely on access to camera and microphone data.
Embrace the Future of Web Development
Apple’s commitment to pushing the boundaries of web technologies is evident in the continuous improvements and additions made to Safari Technology Preview. By providing a platform for experimentation and feedback. The company ensures that developers have a voice in shaping the future of Safari and the web on macOS.
As web applications continue to evolve and become more sophisticated, the need for powerful and efficient web technologies becomes paramount.

Divine Deeper: A Comprehensive Overview
To better understand the impact of the changes introduced in Safari Technology Preview 196. Llet’s explore each area in more detail:
Canvas Improvements
The Canvas API is a powerful tool for creating dynamic and interactive graphics on the web. With the fixes implemented in this release. Developers can expect improved rendering consistency and better error handling when working with canvas elements.
- Visibility Toggling Fix: Previously, toggling the visibility of a canvas parent element would undo the effect of clearRect, leading to unwanted artifacts or rendering issues. This fix ensures that the canvas is properly cleared, regardless of visibility changes. Providing a more reliable and predictable rendering experience.
- Image Exception Handling: When attempting to draw an image that is in a broken state. The drawImage API now throws an exception, allowing developers to handle errors gracefully and provide appropriate fallback mechanisms or error messaging.
Web API Advancements: Enhancing Binary Data Handling
The introduction of bytes support for Blob and PushMessageData objects opens up new possibilities for working with binary data in web applications. This enhancement enables more efficient file transfers, real-time communication, and other use cases that require handling binary data.
Developers can now leverage the bytes() method to access the raw binary data of a Blob or PushMessageData object. Streamlining the process of manipulating and transferring data between the client and server or between different web workers.
CSS and Web Inspector Improvements: Boosting Developer Productivity
The CSS source editor within Safari Technology Preview 196 receives a significant boost with the addition of fuzzy search code completion. This feature intelligently suggests CSS properties, values, and selectors as developers type, saving time and reducing the potential for errors.
Additionally, the fix for the shader compilation issue involving underscore array variables ensures compatibility with a wider range of WebGL applications. Preventing potential rendering issues or errors.
Real-Time Communication Enhancements: Smoother Experiences
Real-time communication applications, such as video conferencing and live streaming, rely heavily on efficient access to camera and microphone data. The reduced delay in the resolution of the getUserMedia promise ensures that these applications can retrieve media data more promptly, leading to smoother and more responsive experiences for users.
