RELEASE NOTES
Private Press 1.2.1
March 26, 2026
Auto-Update
- Fixed update failing on macOS 26 when running from the Applications folder
- Updates now stream directly to disk with real download progress instead of buffering in memory
- Version comparison uses marketing version only — no more build number mismatches between releases
Update Security
- The update helper now verifies bundle identity, team ID, and designated requirements before installing
- Target path restricted to the running app — prevents overwriting arbitrary locations
- Ed25519 signing keys no longer passed as command-line arguments in the release pipeline
Performance
- Signature verification uses memory-mapped I/O instead of loading the full DMG into memory
- Update helper uses instant rename for backup instead of copying the full app bundle
Reliability
- All update helper operations now have timeout watchdogs to prevent hangs
- Helper writes diagnostics to ~/Library/Logs for easier troubleshooting
- Backup restored automatically if install fails after moving the original app
