• Sign in with SSO: GitLab, OpenID Connect, SAML, Google or Microsoft 365, whatever your server offers. Sign-in errors are also clearer now. • Attachments show inline: image previews, PDF cards with the first page and page count, a peek into text and code files, and an audio player with playback speed. Files you opened before open instantly. • Channel Settings > Files lists every file shared in the channel. • New widgets: open a conversation from the Home Screen, or start a message or voice note in a channel with Quick Compose. • iPhone Duo: Threads, Saved and Jump fit in the sidebar toolbar, and thread rows have a cleaner layout. • Reply suggestions appear only when the next reply is clear. A custom suggestion prompt can be reset to the default in Settings. • Faster channel switching, especially with the unread filter, and less background activity. • Fixed server draft sync on Mattermost servers older than version 11. • Fixed a Threads badge that could count threads you had already read. Thanks to Norbert and Yassin for testing and feedback.
