Release notes

v26.2.4

Release date: 2026-06-01

Improved overall Chat UI stability.
Improved sender display names in message cells, quoted messages, and merged forwards by using friend remarks, aliases, and cached display names more consistently.
Improved group info cache APIs by separating Chat UI display caches from SDK group profile updates. Use refreshGroupInfoCache: to refresh local display data and clearGroupInfoCacheForGroupId: to clear one group cache.

Fixed short video preview issues where videos did not autoplay and the video file list could be empty after opening files from the preview page.
Fixed message editing issues where stale edit state could overwrite changes or editing could behave incorrectly after the original message was deleted or recalled.
Fixed conversation state synchronization issues that affected read status sync, draft ordering, and deletion of in-progress media or file messages.
Fixed long-press menu issues, including incorrect menu order and keyboard overlap.
