v1.4.0

v1.4.0 was released on XXXX, 2026.

New Features

• Supported sending and receiving GIF image messages. The GIF image message is a subtype of the image message and will not be compressed.
• Supported setting, updating, and retrieving group avatars.
• Enabled users to receive the following information upon joining a chat room:
  • Current chat room member count: Retrieved via the Room#MemberCount attribute. This count updates when users join or leave the chat room.
  • Chat room-wide mute status: Retrieved via the Room#IsAllMemberMuted attribute. This status updates upon receiving mute/unmute status change events.
  • Chat room creation timestamp: Retrieved via the newly added Room#CreateTimeStamp attribute.
  • Whether the current user is on the chat room allowlist: Retrieved via the newly added Room#IsInAllowList attribute to check if the user is on the chat room allowlist.
  • Mute expiration timestamp of the current user: Retrieved via the Room#MuteUntilTimeStamp attribute.
• Added the new chat room mute event IRoomManagerDelegate#OnMuteListAddedFromRoom(string roomId, Dictionary<string, long> mutes) to provide muted user IDs and their mute expiration timestamps via the Dictionary<string, long> parameter, deprecating the old event IRoomManagerDelegate#OnMuteListAddedFromRoom(string roomId, List<string> mutes, long expireTime).
• Supported retrieving roaming messages sent by specific group members: Added the FetchServerMessagesOption#FromIds attribute to replace the original FetchServerMessagesOption#From attribute.
• Supported retrieving messages sent by specific members within a local group conversation.
• Supported searching for messages across all local conversations by keyword, returning the list of conversation IDs and their matching message IDs.
• Supported retrieving one (via ChatManager#LoadMessage) or more (ChatManager#LoadMessages) local messages by message ID.
• Supported batch notifications via group member join/leave events. Previously, the SDK triggered a separate event for each individual member. The new events IGroupManagerDelegate#OnMembersJoinedFromGroup and IGroupManagerDelegate#OnMembersExitedFromGroup are introduced to replace the deprecated IGroupManagerDelegate#OnMemberJoinedFromGroup and IGroupManagerDelegate#OnMemberExitedFromGroup events.

Improvements

• Changed the unique app identifier from the app key to app ID.
• Supported modifying various message types via the message modification API ChatManager#ModifyMessage:
  • Text and custom messages: Modifying both the message body and extensions (attributes).
  • File, video, voice, image, location, and combined messages: Modifying extensions (attributes) only.
  • Command messages: Not supported.
• Allowed group owners, chat room owners, and administrators to recall messages sent by other users.
• Adjusted the trigger threshold for the IConnectionDelegate#OnTokenWillExpire event; the notification is now triggered when 80% of the token's validity period has elapsed (previously 50%).
• Improved the loading performance of the local conversation list when the latest message is an attachment by eliminating redundant file length checks.
• Optimized specific database operations.
• Optimized the reconnection logic to automatically switch reconnection addresses by default.
• Added the device timezone offset to log files to facilitate troubleshooting.

Issues Fixed

• Messages in memory were not deleted when their corresponding local conversation was removed.
• The TYPE field was empty in the IChatThreadManagerDelegate#OnUserKickOutOfChatThread event.
• IChatManagerDelegate#OnMessageContentChanged failed to return modification details when editing messages other than text and custom messages.
• After a group or chat room was disbanded, the SDK would still fetch group or chat room details from the server after members received the disbandment event.
• The database was mistakenly rebuilt upon encountering a SQLITE_BUSY error.
• The latest message in a conversation retrieved from the server via ChatManager#GetConversationsFromServerWithCursor or ChatManager#GetConversationsFromServerWithPage did not contain translations or message Reactions.
• A crash caused by extreme network conditions.
