1.8.1 (2026-08-07)

A GitHub Actions incident left the 1.8.0 release build queued indefinitely, so no Docker image was ever published for that tag. 1.8.1 re-runs the release with the same code, plus one plugin slot that merged in the meantime.

Features

• Mail: Nest tags in a tree by picking a parent when you create one
• Mail: Per-tag visibility — always, only when unread, or always hidden
• Mail: Assign and clear several tags at once, with a reworked tag display
• Mail: Recover tags from the server by scanning mail for JMAP keywords no local tag explains (#658)
• Mail: "Forward as attachment" in the viewer and the message-list context menu
• Mail: Refresh button in the mail-list toolbar
• Composer: Confirm sending without a subject instead of blocking the send, with "Don't ask again" (#684)
• Contacts: Contact cards for organizations (#701)
• Security: Manage S/MIME and PGP public keys and configure Stalwart encryption at rest from account security settings
• Notifications: Background notification onboarding, sequenced after the PWA install prompt
• Navigation: Deep links for mail, calendar, contacts, files, and settings, with screen-reader improvements
• Settings: Always show the Unified Mailbox switch in Layout settings
• i18n: Catalan translation
• i18n: Localized editor toolbar across every locale
• Plugins: Contact API — contact.get, contact.create, contact.update, contact.search
• Plugins: contact-cryptokeys UI slot, behind the ui:contact-cryptokeys permission, so a plugin can render a contact's crypto keys in place of the built-in list
• Plugins: user.getAccounts and user.getIdentities
• Plugins: user.logout method and logout hook
• Plugins: Crypto API — public-key management and encryption-at-rest control on the privileged tier
• Plugins: onBeforeBlobUpload can offload an attachment to external storage
• Plugins: Binary Blob/File bodies for api.http.post
• Plugins: upfiles.get moved behind email:blob-read, off the privileged tier
• Dev: Mock JMAP defaults now include nested tags

Changes

• Mail: The "Reset to defaults" button is gone from tag settings — one stray click wiped a carefully built tag list, with no confirmation and no undo

Fixes

• Send: Send through the identity's own account client so DKIM matches the From domain (#461)
• Send: Split Name <addr> recipients into the JMAP name and email fields (#672)
• Send: Time out stalled JMAP requests so a send can't hang forever (#702)
• Mail: Keep inline images when replying to application/octet-stream cid parts (#543)
• Mail: Reply on your own thread message no longer re-addresses the original recipients (#703)
• Mail: Empty folder no longer stops after 500 emails (#711)
• Mail: Move messages across accounts from the "Move to" context menu, preserving read state and deferring source removal to Stalwart
• Mail: Stop resurrecting deleted rows in the mailbox refresh merge
• Mail: Keep the message/rfc822 attachment visible after inline unwrapping
• Mail: Strip sender and recipient names from forward-as-attachment filenames
• Mail: Open mailto: links in the built-in composer
• Mail: Spell out the full tag path in drag-and-drop toasts, so Personal/Receipts and Work/Receipts no longer read as the same tag
• Mail: Act on current email state in the context menu's mark-as-read instead of a stale copy
• Mail: Match the selected-row tint between dark and light mode
• Mail: Restore lost animations after the Tailwind config move
• Drafts: Restore the sender identity when reopening a draft
• Calendar: Stop re-adding the organizer to the attendee list on every save (#731)
• Calendar: Stop re-probing shared accounts that have no calendar access
• Calendar: Route the parse dump through the debug logger
• Contacts: Stop minting duplicate "Trusted Senders" address books (#730)
• Contacts: Hide Contacts and Calendars when the account lacks the JMAP capability
• Contacts: Require an explicit shared-account fallback for contacts and calendars
• Files: Show the modification date instead of the creation date (#700)
• PWA: Honor the configured theme color in the desktop title bar and keep it in step with the active theme (#671)
• Accounts: Reconcile the stale persisted account chip after an impersonation handoff
• Auth: Only request a credential cookie when the server has a SESSION_SECRET
• JMAP: Split requests to stay inside the server's advertised limits — maxCallsInRequest, maxObjectsInGet/InSet, maxSizeRequest, and concurrency
• JMAP: Treat an aborted SSE connect as a close, not a failure
• JMAP: Surface the underlying network error cause in passthrough failures
• Settings: Avoid leaving TZ="undefined" when restoring an unset timezone
• Plugins: Stop a privileged plugin from reading another privileged plugin's PRF secret
• Plugins: Correct the method names for message errors and crypto.getPublicKeys
• i18n: Restore key parity across locales and the English send_timeout string
• Docs: Document the remaining env vars in the env templates, and correct the facts and headings in README and FEATURES
