# Release 5.3.39

## What changed

- In **Telegram**, you can set **keyboard button styles** (for example primary, success, or danger) to highlight key steps in a scenario.
- **Telegram group reactions** are stored and shown more reliably in the operator experience, including when the update payload is non-standard.
- For the **web widget**, you can set a **custom channel icon** in the operator line so different entry points are easier to tell apart.
- **Quick replies** in the message editor safely insert text that contains characters like `<` and `>`, and **multi-line** content keeps its line breaks.
- **Operator workload reports** fix time-in-status calculations and the daily **timeline**, reducing stuck segments and incorrect totals.
- For **external integrations** that load large dialog lists, requests now have a **bounded wait time**; a **lighter field set** is available when you do not need the full record.

## How it changed

**Previously**, Telegram keyboard buttons could not be styled from the builder; group reactions sometimes failed to persist or display; every widget looked the same in the chat list; quick replies with special characters could break the editor HTML; operator status statistics could show timeline anomalies; very large dialog list queries could run too long or use excessive resources.

**Now**, button styles are configured in the constructor and reach Telegram clients; group reactions are handled more defensively; widget icons can be customised per setup; quick-reply insertion escapes risky characters and preserves line breaks; status timing aligns better with real state changes; large dialog lists can be fetched in a compact form with controlled response time.

**Why it matters:** clearer Telegram journeys, fewer surprises in conversations, more trustworthy supervisor metrics, and less load spikes from integrations.
