Meridian 1.54.0

August 7, 2026

Lock Meridian with Touch ID, find activities from Spotlight, preview attachments with Quick Look, and send replies that keep the conversation — plus more dependable AI enrichment.

New

• Touch ID app lock — Optionally require Touch ID (or your password) to open Meridian, keeping your mail, calendar, and contacts private on a shared desk.

• Activities in Spotlight — Opt in to Core Spotlight indexing and your tasks and events show up in macOS search, right next to everything else.

• Quick Look for attachments — Select an attachment and press Space for an instant full-size preview, no download or app switch needed.

• Notification filtering per source — Choose which accounts may notify you, so a noisy inbox can stay silent while the important one comes through.

• Snooze from Shortcuts — A new Snooze Task intent works with Shortcuts and Siri, and understands which task you mean.

• Smarter Quick Add — Type “2–3pm” and get a start and end time, mention people to add them as meeting guests, and paste a video-call link to attach it to the event.

• Deeper Microsoft integration — Contact edits and categories now sync back to Outlook, and you can flag message importance from Meridian.

Improved

• AI enrichment that keeps up — An on-device AI engine upgrade fixes a bug that left some converted tasks stuck “Preparing” forever — most noticeable with alert-style emails full of links and codes. Anything still waiting will finish enriching on its own after the update.

Fixed

• Replies keep the conversation — Replies sent from Meridian now include the earlier correspondence below your message, the way recipients expect — so nobody loses the context.

• Trash that sticks — Moving a message to Trash now syncs reliably to Gmail instead of silently failing in the background.
