Released July 20, 2022 — Version 15.6 (17613.3.9)

## Overview

Safari 15.6 ships with the iOS & iPadOS 15.6 and macOS 12.5.

### CSS

#### New Features

- Added support for `:modal` CSS pseudo-class.

#### Resolved Issues

- Fixed `object-fit` causing iframe contents to shift.
- Fixed inert behavior to apply to `::after`, `::before`, and `::marker` pseudo-elements.
- Fixed `:focus-visible` matching a mouse click after a second `element.focus()` call.
- Fixed logical inline and logical block viewport units to be based on the current element’s `writing-mode`.

### Editing

#### Resolved Issues

- Fixed resetting writing direction when inserting a new paragraph breaks out of a quoted reply block.
- Fixed managed pasteboard on iOS to work for all managed locations including managed Safari domains.

### Fonts

#### Resolved Issues

- Fixed automatically updating page layout when new fonts are installed.

### HTML

#### Resolved Issues

- Fixed `<link rel=preconnect>` to respect `crossorigin=anonymous` and prevent sending credentials to different-origin links.

### Media

#### Resolved Issues

- Fixed blank video playback with only audio.
- Fixed replaceTrack with different constraints preventing sending packets.
- Fixed WebAudio playback rate speeding up for a few seconds when using `createMediaElementSource`.
- Fixed stalled playback when seeking in a xHE-AAC track backed by a SourceBuffer.
- Fixed starting audio playback in Safari when the device is locked.
- Fixed playback for video when the timeline sometimes goes backward at the start of playback.
- Fixed capturing and rendering audio simultaneously.

### Rendering

#### Resolved Issues

- Fixed flickering when rendering overlapping negative `z-index` layers.
- Fixed disappearing multi-column content inside a fixed position container when scrolling.
- Fixed images displayed in Reader not appearing in a print job or PDF export.

### WebAuthn

#### Resolved Issues

- Fixed missing text in a sign-in sheet when registering a passkey with syncing platform authenticator disabled, if Touch ID isn’t configured.

### Web Animations

#### Resolved Issues

- Fixed computing implicit keyframes when either a 0 percent or 100 percent keyframe (or both) define only a timing function.

### Web API

#### Resolved Issues

- Fixed communication between BroadcastChannel instances in distinct opaque origins.

### Web Inspector

#### Resolved Issues

- Fixed resources from memory cache showing empty content in Network, Sources, and Search tabs.
