2.2.0 - Universal & Modern macOS Compatibility

What's New in 2.2.0

This release modernizes Brooklyn for modern macOS (Sonoma, Sequoia, and later), introducing native Apple Silicon (arm64) support alongside Intel (x86_64) in a Universal 2 binary, while resolving major issues with screensaver termination, video player resource deallocation, and multi-instance memory leaks.

Highlights & Fixes:

• Universal 2 Binary: Full native execution on Apple Silicon (arm64) Macs without needing Rosetta 2, while retaining full compatibility with Intel (x86_64) Macs.
• macOS Sonoma+ Exit Lifecycle: Listens to com.apple.screensaver.willstop to cleanly terminate the out-of-process legacyScreenSaver.appex extension when the screensaver stops, eliminating zombie processes and high background CPU usage.
• Hardware Decoder & Player Resource Release: Fixed an issue where stopAnimation() failed to release AVPlayerItems and videoLayer.player, allowing the system's VTDecoderXPCService hardware decoder to terminate cleanly on exit.
• Prevent Unbounded Loop Queue Growth: Scoped AVPlayerItemDidPlayToEndTime notifications to prevent cross-insertion of duplicated queue items between multiple display/preview instances.
• Reduced Overhead: Removed the unused 30fps empty timer loop (video playback is fully handled by AVFoundation).
• Swift 6 & Modern Build Settings: Fixed Swift 6 syntax warnings and unbundled obsolete 2020 Swift runtime dylibs, linking against macOS built-in /usr/lib/swift.
