# Release 5.6.9

## What's changed

- **Operator settings:** fields validate in real time with clear error messages; user table sorts by role, manager, and schedule; duplicate file extensions are blocked; hot key conflicts are visible on the settings page.
- **Broadcasts:** filters work more reliably; the system doesn't skip criteria; the old broadcast interface now recommends switching to the new constructor.
- **Stability:** fixed a memory consumption issue that caused system instability.
- **OperatorLine:** chat and contact details adapt to window size without horizontal scrolling; system messages are labeled correctly; long text is truncated with a tooltip on hover.

## How it's changed

**Before:** Settings errors were not obvious; broadcasts could fail with filters; the system experienced instability under load; OperatorLine layout broke in narrow windows; system messages displayed incorrectly.

**Now:** Validation happens in real time; broadcasts process reliably; the system is more stable; layout adapts to window size; system messages are labeled correctly.

## Why it matters

Operators find it more comfortable to configure their screens; broadcasts become a more reliable communication channel; the system runs without interruptions; operators are more comfortable working on screens of any size.

## Details by product section

### Settings — operator screens

**Improved**

- **Hot keys:** conflicts appear on the settings page in real time; the error is visible when the first block is also open.

- **Session timeouts:** the "Save" button is disabled if timeout is enabled but minutes are not set; validation happens live.

- **File management:** the system warns when trying to add an extension that already exists; saving is blocked until extensions are normalized.

- **Users and roles:** the user table sorts by displayed text (role name, manager name, schedule name); required fields are visually distinguished; user form shows `*` next to password in create mode; custom field types `SELECT` and `SELECTAPI` work; schedule remains visible even if the operator doesn't have access to calendars.

### Broadcasts

**Fixed**

- **Contact filtering:** the system no longer accepts invalid filter parameters; filters work correctly when selecting contacts by channel.

- **Temporal fail-fast:** the system doesn't retry requests that contain SQL errors; deterministic errors (bad column name, syntax) are immediately treated as non-retryable.

- **Recommendation to switch to new constructor:** the old broadcast interface shows a message about the more powerful new constructor with a link (if configured).

### OperatorLine — chat and details

**Improved**

- **Layout in narrow windows:** chat list, contact details panel, and request details adapt to window size without horizontal scrolling; long text is truncated with ellipsis.

- **Tooltips on hover:** if text is truncated, the full text appears on hover (in contact details, requests, but not system messages).

- **System messages:** chat list correctly displays system messages (for example, chat status changes) even when the payload doesn't contain explicit labels; instead of the sender's name, a "System message" label is shown.

### Stability

**Fixed**

- Fixed a critical issue that caused excessive memory consumption during intensive constructor and operator use.

## Please note

- The recommendation to use the new broadcast constructor is available if `url_to_new_design` is set in instance settings.

- Tooltips in contact details can be selectively disabled for specific fields.

- System messages in the older API might not have had explicit labels; the recognition algorithm is based on type, sender, and content.
