Added

• Added independent local account labels, visible alongside mailbox addresses, with v3 backup support and imports from v1/v2 backups (#79).
• Added OAuth mailbox verification and an in-place repair preview that preserves existing messages, user names, labels and account IDs (#78, #79).
• Added a one-time sender-name notice with a preview and a shortcut to account settings (#77).
• Added a local address book with searchable contacts, multiple labeled email addresses, favorites, notes, and quick create/edit actions from message participants (#81).
• Added recipient suggestions that prioritize saved contacts while retaining recent correspondents, with controls to suppress unwanted recent addresses (#81).
• Added standards-compatible vCard import and export with duplicate merging, partial-error reporting, UTF-8/folded-line support, and safe file/card limits (#81).
• Added contacts to local file and WebDAV settings backups, with backward-compatible imports (#81). Fixed
• Fixed partial Outlook sync updates clearing message subjects, bodies, metadata, and attachments after read or flag changes (#90).
• Fixed SMTP and Gmail dropping configured sender names. Structured From headers now support Unicode and punctuation, and outgoing retries preserve the stored sender identity (#77).
• Outlook now clearly shows its provider-managed sender name; changing a local label does not change the external identity. New OAuth accounts bind to a verified provider identity, and OAuth addresses cannot be changed through ordinary account editing (#77, #79).
• Settings restore preserves existing OAuth mailbox addresses and connected credentials instead of silently replacing them with another mailbox from a backup.
• Fixed copied-text feedback leaving a timer running after its popover was closed.
• Fixed vCard export/import losing whitespace at folded boundaries and treating carriage returns inside notes as new contact properties.
• Fixed participant actions associating a newly saved contact with an email address removed in the editor; recent-suggestion removal is now reachable by keyboard.
• Blocked queued SMTP sends after the account mailbox address changes, while retaining frozen names when only a name changes.
• OAuth remote drafts now use the same verified identity and connection as sending. Failed identity checks preserve encrypted local drafts without uploading them.
• Corrected backup restore feedback to explain that existing OAuth connections and mailboxes with local data are preserved. Upgrade notes
• Review existing sender names before sending: the old “Display name” setting is now included in SMTP/Gmail outgoing mail. Use the separate “Account label” for internal descriptions. Previously delivered messages are unchanged.
• Queued messages retain their original identity. Messages with missing or incompatible identities stop automatic retries and remain visible for review; unknown send outcomes are never automatically resent.
• Outlook sender names remain controlled by the mailbox service. This change does not enable aliases or delegated sending, and recipient address books may affect how names appear.
• New backups use schema v3. Upgrade other clients before importing them. Existing OAuth connections are preserved during restore; a new account can still restore its saved credentials. Settings backups do not include message bodies or attachments.
• Automated tests and package builds cover client behavior. Live SMTP/Gmail/Outlook recipient-side delivery has not been exercised for this release; provider rewriting and recipient address-book display remain outside the client guarantees. Verify your sender name with a test message before formal use.
