## Summary

As the web continues to evolve, standard bodies like the W3C Technical Architecture Group, TC39, and the IETF are actively reviewing proposals to ensure the platform remains robust and versatile for developers. Recent landmark additions address long-standing architectural pain points, such as the introduction of the `using` keyword in JavaScript for explicit resource management (`Symbol.dispose`), and the newly published HTTP `QUERY` method. Formally published as RFC 10008, this long-awaited method finally provides a safe, idempotent way to send request bodies for data fetching without artificially relying on POST.

Simultaneously, the browser is increasingly matching native application capabilities through deep structural and visual enhancements. Developers can anticipate native platform support for reactive state management via Signals, allowing frameworks to hook directly into the browser. Layout innovations are also expanding with CSS grid lanes to natively power masonry layouts, as well as new CSS gap decorations. Furthermore, Progressive Web Apps (PWAs) are growing with manifest localization and system-level dark color schemes, while the View Transitions API introduces element-scoped transitions that make complex single-page application animations effortlessly fluid with minimal code.

Looking forward, the web is charting radical new territory in user identity and artificial intelligence. The Digital Credentials API proposes bridging mobile wallets with websites for identity reporting—a feature the architecture board labeled as "satisfied with concerns" due to significant privacy debates surrounding age validation and region restrictions. In tandem, local AI execution is solidifying as a standard web primitive. Web applications will soon leverage hardware-accelerated machine learning via the WebNN API to process workloads on local NPUs, or utilize built-in browser LLMs to execute offline prompts. Most disruptively, the rise of "agentic browsing" powered by the WebMCP protocol will allow web applications to expose their toolsets directly to autonomous AI agents, fundamentally shifting how tasks are executed across the internet.
