Safari Technology Preview 247 brings a range of bug fixes and new features across CSS, SVG, accessibility, media, networking, and rendering. Notable additions include support for `calc-mix()` in CSS, color space overriding for hardware video decoders in WebCodecs, MathML embellished operator detection, and a Safari MCP server for WebDriver agent connections. Numerous SVG rendering bugs are fixed, including issues with `getBoundingClientRect()` on `<tspan>`, `clip-path` zoom handling, and animated GIF freezing. Networking improvements address multiple HTTP cache-control directive handling issues. Accessibility fixes resolve VoiceOver navigation and ARIA exposure problems.
