# Release 5.3.13

## What Changed

- **Topic change dialog.** Fixed topic selection and display of the topic in the chat header.
- **Operator replies across channels.** Fixed a bug where the operator reply could attach to the wrong message when multiple channels exist. The system now correctly identifies the message by chat room.

## How It Changed

### Topics and chat header

**Before:** Topic selection and path in the topic change dialog could display incorrectly; the header topic for nested topics could be unclear.  
**Now:** Topic selection and path expansion work correctly; the topic in the chat header is shown clearly.  
**Why it matters:** Operators can navigate topics and dialog context more easily.

### Replies across chat rooms

**Before:** With multiple channels/chat rooms, an operator reply could attach to the wrong message.  
**Now:** The system uniquely identifies the message by chat room, so replies go to the correct dialog.  
**Why it matters:** No confusion between dialogs and channels.
