Letterboxx 1.0.5

1.0.5 (10)Previous: 1.0.4 (9)Updated May 31, 2026 at 12:29 AM CDT

This update adds subscription access for Letterboxx, polishes first-run onboarding, and improves background delivery stability.

Added a polished App Store subscription screen with monthly and annual options.
Added Restore Purchases support.
New users now see a brief welcome flow first, then choose subscription access before connecting a mail account.
Improved the subscription step with StoreKit-backed pricing, Letterboxx plan cards, and clearer "What you get" value copy.
Improved onboarding window sizing so welcome, subscription, and account setup steps each get the right amount of space.
Eligible App Store accounts can start the trial through Apple's purchase sheet.
Sync and import now require active subscription access.
Improved automatic background delivery so new-newsletter sounds only play when Letterboxx is active and visible, reducing a rare wake/background crash risk.

Release

1.0.4 (9)Previous: 1.0.3 (8)Updated May 26, 2026 at 11:33 PM CDT

This update makes Letterboxx easier to understand and easier to learn from inside the app.

Added Help menu entries for the Letterboxx User Guide, What's New, and Keyboard Shortcuts.
Added a native searchable Keyboard Shortcuts window.
Improved account setup and onboarding language to explain that Letterboxx imports newsletter copies from selected IMAP folders into a local reading library.
Clarified that original messages stay in the connected mail account unless you delete them and then remove them from Letterboxx's Trash.
Improved wording around IMAP INBOX and Letterboxx Inbox so server folders and local app organization are easier to tell apart.

Release

1.0.3 (8)Previous: 1.0.2 (7)Updated May 26, 2026 at 9:37 PM CDT

This update improves read and unread handling for connected mail accounts, while keeping Letterboxx fast and local-first.

Added per-account Read status controls in Settings > Accounts.
Choose whether each account keeps read/unread changes local, sends them to the mail server, or also refreshes recent read/unread status from the mail server during checks.
Account setup and onboarding now clarify that Letterboxx imports newsletter copies from selected IMAP folders, that your original messages stay in your connected mail account unless you delete them and then remove them from Letterboxx's Trash, and that downloading newsletters does not mark messages read on the server.
Local reading stays immediate; optional mail-server updates run quietly in the background, with lighter read-status refresh work during sync.
Existing accounts can now save Read status changes without retesting the connection when connection details have not changed.
Menu commands now stay disabled until the needed account setup or newsletter selection is available.
Fixed a rare crash path in the newsletter list's native Mac swipe-action support.
