The Edge 2025 web platform top developer needs dashboard

[TWF Bot]

For the fifth year in a row, together with our partners at Igalia, Google, Mozilla, and Apple, we're working hard on improving the consistency of some of the major features which web developers need the most. Indeed, the Interop 2025 project is now operating at full speed and already bearing fruit: the overall interop score has now reached 50%, up from its starting 28% score at the beginning of the year. Interop is the most effective way we have to collectively catch up on implementation differences and bugs. The project has a good track record of bringing implementations into alignment for the areas that are selected. However, there's more that web developers need. On the Microsoft Edge team, we're always listening to developers, whether through surveys, bug reports, or direct collaborations. Through this listening, we know that developers have been asking for more than what the Interop project's consensus process selects. We want to help raise the visibility of these needs and track progress from browser vendors to implement them. To that end, we're announcing our updated Edge 2025 web platform top developer needs dashboard. Like last year, our dashboard tracks compatibility and test success (as measured by the WPT project) of important features like:

• Scroll-driven animations, which enable smooth, multithreaded animations in response to user scrolling.
• Cross-document view transitions, which smoothly animates between multiple pages of a site.
• Render blocking, which delays rendering until certain scripts or stylesheets have loaded; an important improvement for delivering smooth page transitions.
• Container queries (including style queries), which apply styles to elements based on the dimensions, or styles, of a container element.
• Fetch upload streaming, which sends ReadableStream objects to the server without punishing device memory.
• The ::marker pseudo-element, which styles list item bullets or numbers.
• Speculation rules, which hint the browser to proactively download pages in the background, providing near-instant page loads for a large fraction of sessions.
• And more on the dashboard.

If you have feedback or think there are items we've missed, please let us know by leaving a comment about the dashboard. The Edge web platform team is committed to transparency and openness. We hope that by providing a fuller picture of what we're hearing we can play a positive role in improving the platform for everyone.
