Mattermost: iPhone vs Android

Devices with iOS 18.0+ are required. Server version v11.7.0 or later is required. - Improved the Direct Message call experience to behave more like a native phone call. - Added tappable tel: links for phone numbers in posts, which open the device calling app. - Added support for the automatic cache cleanup setting provided by the server, performing rolling cleanups of cached content to prevent it from accumulating. - Added collapse and expand all checklists, and task filtering by state and assignee, to playbook runs. - Updated onboarding and server connection welcome messaging. - Updated timezone data so mobile timestamps reflect 2026 changes in Alberta, Northwest Territories, Morocco, and Western Sahara. - Fixed an issue where channel links ending in a channel ID failed to open. - Fixed an issue where urgent mention badges used normal mention colors in the channel list. - Fixed an issue where pasting a full server URL containing a path, such as a channel link, into Add Server showed a confusing error instead of connecting. - Fixed an intermittent issue where answering an incoming call from the iOS lock screen immediately disconnected. - Fixed an issue where the tool approval user interface briefly offered Accept/Reject for AI tool calls configured to run automatically, which could race with server-side auto-execution. Interrupted auto-run tool rounds now show a Run tools option instead of approval buttons. - Fixed an issue where session attributes always reported a VPN as active and sent an incorrect client IP address. - Fixed agent tool approvals that could fail to submit or lose their buttons after an error. Added support for agent questions (AskUserQuestion).
