Apple has launched a "Switch to Safari" campaign urging Mac users to drop Chrome, with a web page listing more than 10 reasons. Its speed and battery figures are Apple's own "up to" claims, and the coverage shows no change in Mac browser share.

buildOne report1 publisher Safari leaves 382 points of layout on the iPhone Duo's 466-point outer screen, one studio found
Web teams should test layouts at 382, 466, 626 and 890 points before the iPhone Duo goes on sale October 23, a dev.to checklist says. Three of those widths are Apple's pixel counts divided by 3; 382 is one studio's simulator reading.

buildOne report1 publisher CSS text-box-trim crops headline space using the font's own metrics
CSS text-box-trim crops a headline's box to the font's cap height and baseline, replacing negative margins like -0.18em tuned by eye in devtools. The browser takes the numbers from the font file, so swapping the typeface or raising line-height no longer means retuning a margin.

Mermaid 12.0 redraws the flowcharts and class diagrams teams have already published
Mermaid 12.0 re-lays out and recolours existing flowcharts, state and class diagrams by default, and requires ES2024 and Safari 17.4 or later. Three config settings restore the old look, but older browsers need a polyfill or transpile step.

Fake iPhone Duo preorder page fires the DarkSword exploit chain the moment it loads
Scammers wrapped the leaked DarkSword exploit chain in a fake iPhone Duo preorder page that attacks the moment it opens, before any form, tap, or download. Apple has already patched the flaws it uses, so a current iOS build is what protects a phone here.

buildOne report1 publisher Staying lazy until the sort cuts a chain's 80,000-object peak to about 2,000
TC39's iterator helpers are Baseline as of September 2026, so lazy chains run without a polyfill from Chrome 122 and Node 22 upward, while the teams reporting the 40-60% memory saving attached to them are unnamed.

The new WebKit preview matches style-originated scroll timelines globally, so a declaration no longer has to sit in the animated element's tree. Four of the seven animation entries in the notes settle which timeline a target resolves to.

buildOne report1 publisher The screen eyedropper you write in canvas stops at the edge of your own page
getImageData can only ever read pixels your own code painted, and the screen-capture workaround reaches the rest of the display only with a permission prompt and a recording banner. Chromium has shipped window.EyeDropper since late 2021.

Apple deprecated WKProcessPool in macOS 12 and it no longer affects process sharing, so the data store object you hand a web view is what now determines whether two tabs share WebKit's network and content processes.

buildOne report1 publisher On iPhone Safari, a finger over the speaker cut the avatar's own turn five milliseconds later
When the acoustic path changes mid-playback, the browser's echo canceller stops cancelling and the leftover sound reaches the voice detector as speech. The fix was 300 extra milliseconds, applied only during playback.
