Bug Fixes

Safari Compatibility Fix

This release resolves an issue where the Ghost editor would fail to load in Safari browsers earlier than version 16.4. The problem was caused by the use of negative lookbehind assertions in regular expressions within the @tryghost/koenig-lexical dependency.

Negative lookbehind is a regex feature that wasn't supported in Safari until version 16.4, causing editor initialization errors for users on older Safari versions. The updated dependency now uses alternative regex patterns that are compatible with all supported browsers.

New Features

No new features were introduced in this patch release. This update focuses solely on fixing a browser compatibility issue with the Ghost editor in older Safari versions.

Security Updates

No security fixes were included in this patch release. The update addresses a browser compatibility issue only.

Performance Improvements

Impact Summary

This patch release has a moderate impact focused on browser compatibility. It resolves an issue that prevented content creators using older Safari browsers (pre-16.4) from accessing the Ghost editor due to unsupported regular expression syntax.

By updating the @tryghost/koenig-lexical dependency to use compatible regex patterns, Ghost now provides a more consistent editing experience across all supported browsers. This change is particularly important for organizations with users on older Safari versions who previously encountered errors when trying to create or edit content.

The fix is transparent to end users and requires no configuration changes, making it a straightforward but valuable update for maintaining broad browser compatibility.
