EternoMail

CHANGELOG

Eterno Mail — v0.3.6

• Improved expanded and compact sidebar sizing, icon alignment, tooltips and the Compose button for clearer navigation.
• Fixed unstable message-list scrolling and scrollbar behavior on Linux/WebKitGTK.
• Made message moves and Trash actions update the local view promptly, with safer IMAP reconciliation.
• Improved Undo reliability when restoring moved messages.
• Fixed Gmail Trash and Spam actions targeting incorrect destination mailboxes.
• Refined conversation-viewer interactions and action feedback.
• Added release notes for the installed version directly to the What’s New dialog, using the project’s changelog.
• Fixed HTML and JavaScript injection through OAuth callback error codes and descriptions.
• Fixed concurrent OAuth session access during login and cancellation, and prevented an older callback from clearing a newer session.
• Required SMTP STARTTLS connections now close with an error when the server does not offer encryption, preventing plaintext fallback.
• Hardened attachment saving against unsafe filenames, parent-directory traversal and symlinks escaping the destination; Save All sanitizes filenames before building paths.
• Fixed attachment downloads with empty or short message IDs and prevented simultaneous downloads from overwriting the same default filename.
• Added S/MIME verification against system trust roots and stopped caching certificates classified as unknown signers. Existing self-signed and expired-certificate exceptions now require a valid cryptographic signature.

Security

• internal/crypto: device key now uses a versioned format (v2). Existing installations with the legacy format (v1) are automatically migrated on first startup: all database credentials are transparently re-encrypted with the new key derivation — no user action required. Legacy v1 support will be removed in Aerion 0.5.0.

Eterno Mail — v0.3.5

• Fixed first-launch interaction becoming blocked after dismissing the startup dialogs.
• Fixed Enter and Space activation for focused interface buttons.
• Improved startup dialog sequencing and cleanup to prevent stale modal input locks.
• Improved external-link handling in the Terms and OAuth dialogs.
• Updated the What’s New dialog to use the actual runtime version.
• Improved Flatpak development builds inside container environments.

Eterno Mail — v0.3.4

• Added unified Drafts, Sent, Trash, Starred, Archived, Spam/Blocked and All Mail views across enabled accounts.
• Added account-specific special-folder drill-down and Gmail-compatible virtual Archived views.
• Improved draft safety with canonical draft references, sender identity persistence and attachment-safe Save & Close.
• Improved detached composer persistence so quick closes no longer lose or duplicate pending drafts.
• Added automatic background and manual GitHub release update checks.
• Added Priority, Categories and Chronological inbox display selection.
• Added localized tooltips to conversation viewer actions.
• Improved KDE Wayland/X11 titlebar compatibility.
• Updated public project documentation and interface refinements.

Eterno Mail — v0.3.3 development
