# Release 5.7.3

## What Changed

- **Operator Line:** the **Last Response At** filter now selects conversations by the time of the client’s last message, including saved filters.
- **Settings — Users:** fixed an error when opening the list or searching by email — the page no longer fails with an unknown column message.

## How It Changed

**Before:** The Last Response At filter could return the wrong set of conversations or ignore the date range — the system used record update time instead of the client’s last message time. In Users settings, email search sometimes blocked the list from loading.

**Now:** The date range in the filter is aligned between the interface and conversation search; saved filters with older settings still work. The user list and email search open without error.

## Why It Matters

Operators and supervisors find conversations where the client is waiting for a reply. Administrators manage accounts through Settings search without interruption.
