[v1.7.3] - 2026-09-11
Why Upgrade
- Completes macOS 27 release readiness while keeping existing deployment targets and runtime availability checks for older systems.
- Makes macOS theme changes, settings updates, and document-tab activation more responsive by avoiding redundant preference and window-composition work.
- Restores a coherent system-glass appearance across visionOS themes and reading surfaces.
Highlights
- Enables the macOS 27 Agent Mode sources in Xcode 27 App Store and notarized builds while preserving runtime availability checks and older-OS compatibility.
- Validates the application with the macOS, iOS/iPadOS, and visionOS 27 SDKs accepted by App Store Connect.
Fixes
- Prevents a theme selection from publishing ten process-wide preference changes and removes unrelated full-window composition work from theme updates.
- Avoids unnecessary editor highlighting and window-chrome refreshes during macOS settings changes and tab activation.
- Keeps visionOS System Glass light in light mode and prevents mixed light and dark surfaces in Paper and other appearance themes.
Breaking changes
- None.
Migration
- None.
Maintenance
- Moves hosted platform, release-validation, and notarized-release jobs to GitHub's
xcode-27runner and verifies the macOS, iOS/iPadOS, and visionOS 27 SDK paths before compiling them in CI; production archives continue to reject beta Xcode builds. - Centralizes Xcode and SDK validation across CI and release workflows and correctly rejects both
Xcode-beta.appand underscored beta installation names from production archives.
