# Release 5.6.6

> Mass broadcasts run in an updated mode: you see audience build progress, and delivery logs are separated from service notes about audience build. After a send, an open customer chat can show a service row with text and an image. In WhatsApp, when the 24-hour reply window is closed, you can send an approved message template. In **Add to chat**, long operator lists load in chunks as you scroll; copying field values works when the browser blocks normal clipboard copying.

## Broadcast

**Improved**

- **New runs** use the updated flow: large audiences show a recipient-build phase and progress, with recovery after temporary failures.

- **Very large filtered lists** are handled in chunks so the send does not fail on a single oversized list.

- **Business hours** are re-checked during long sends so messages do not continue after the window closes when that is configured.

- **Logs.** Delivery events are separated from service entries for audience-build issues; channels and logs appear as distinct sections within the broadcast window.

- **Autobroadcasts.** Time-of-day windows match the values saved in settings; creating or removing an autobroadcast from a scenario finishes predictably—you see a clear success state or an understandable error message.

## Clients (Broadcast module)

**Improved**

- **Contact counts by channel** in **Clients** while preparing a broadcast: see counts per channel to estimate reach before you launch.

## Operator Line — WhatsApp

**New**

- **Template sending** after the 24-hour session expires: instead of the usual composer, you step through an approved template with preview and placeholders.

**Fixed**

- **Flickering “template required” state** while message history is still loading.

## Operator Line — add chat user

**Improved**

- **Operator list** loads long lists in chunks as you scroll; search waits briefly after you type. Search can use email and phone when stored on the profile.

## Operator Line — fields and system messages

**Improved**

- **Copy on click** for field values works when the browser restricts copying; you get confirmation or a clear error.

- **Rows after a broadcast.** The dialog can show a dedicated block with formatted text and an optional image.

- **Line breaks** stay visible for light formatting (such as links or emphasis); large layout blocks still use the structured layout.

## Widget and scenarios — slider

**Improved**

- **Buttons on the slider step** in the web widget: show buttons under the message or a classic keyboard, depending on step settings.

- **Slider step** in the widget and Constructor keeps keyboard type, buttons, and “by state” routing with its parameter when the scenario is converted between builder views.

## Scenario Builder

**Improved**

- **Step properties panel** no longer pulls drafts and statistics from the previously selected step when you switch—fewer accidental edits.

## Please note

- Features your administrator turns on (including extended ticket analytics options) appear only after they are enabled in your environment.

- After Constructor screen updates, review the **Clients** area in the Broadcast module if you have a non-standard rollout.
