# Safari 16.6 Release Notes Released July 24, 2023 — Version 16.6 (18615.3.12) ## Overview Safari 16.6 is available for macOS Big Sur, macOS Monterey, macOS Ventura, iPadOS 16.6, and iOS 16.6. ### CSS #### Resolved Issues - Fixed using `currentcolor` with `color-mix()`. - Fixed content at `block-start` edge to have their trimmed margins reflected in the computed style. - Fixed trimmed `block-end` margins for block containers to be reflected in the computed style in a horizontal writing mode. - Fixed compression streams to handle large outputs during the flush stage. - Fixed trimming nested self-collapsing children at `block-end`. - Fixed the CSS `hypot()` function sometimes returning the result squared. - Fixed container query length units to use the content box instead of the border box. - Fixed serializing properties directly in the parent group rule only for the first nested style rule. ### Forms #### Resolved Issues - Fixed the value not updating on `` and `` elements. ### Web API #### Resolved Issues - Fixed `putImageData` to draw on the correct canvas. --- Copyright © 2026 Apple Inc.
