Top browser updates for the week of Oct 26 – Nov 1
Chrome 156 ships native CSS random() and begins migrating IndexedDB to SQLite, while Safari 27.2 adds ::field-content for customizable selects.
👩💻 Chrome 156
In Chrome 156, native CSS gets the long-awaited random() function for generating random values within a given range without JavaScript, along with a new :navigation-source pseudo-class for tracking the element that initiated a page navigation. The browser also stopped caching failed JS modules—retrying import() loads after network errors—and began a gradual migration of IndexedDB from LevelDB to SQLite.
👩💻 Safari 27.2
In Safari 27.2 and Technology Preview 255, the headline update is an improvement to Customizable Select: the new ::field-content pseudo-element lets you style the selected option’s text directly in the DOM. In addition, the Grid Lanes specification renames flow-tolerance to fit-tolerance, fixes safe/unsafe alignment for fixed-position boxes in anchor positioning, and removes the 7-day cap on cookie lifetime when using CNAME cloaking.
