What's New in MattCha for Mattermost

1.1.17

September 30, 2026

• New: code blocks are syntax-highlighted, with automatic language detection. • Checklists, quotes and bullet lists render cleanly, and thread, search and saved-message titles no longer show Markdown symbols. • Opening a channel is calmer: no brief flash of the previous channel and no rows jumping while messages are marked read. • More reliable unread counts: fixed a badge that kept flipping between two numbers and a badge that never cleared after your own posts. • Channels set to mark unread for mentions only no longer show every message as unread. • "Load older messages" only appears when there really are older messages. • Long messages expand reliably with Show More, and a long press anywhere on a message shows its actions. • Attachment previews show the real file name. • iPad: the voice recorder fits its sheet, the sidebar closes after you pick a channel on smaller iPads, and file previews show a single Share button. • VoiceOver reads message text instead of Markdown symbols.
