# Release 5.7.4

## What Changed

- **Operator Line — new email (Write to client):** **From** stays empty until you select a process in **Select process (direction)**; after selection it fills with that process mailbox (not the instance default); changing the process updates **From**; you can pick another mailbox from the list manually.
- **Auto-distribution and dialog limits:** rooms for **resolved tickets** where the operator was still marked connected **no longer consume** a `max_dialogs` slot — distribution and queue monitoring count only active dialogs.
- **Email — OAuth binding:** the system **does not create** mailbox records without an address; existing empty entries are removed on the next bind or unbind — more reliable send/receive after OAuth.
- **Telephony:** the channel form adds **Action on enrich error** — what to do when the webhook enrich action fails (do not assign / skip auto-transcription, or assign a default administrator).

## How It Changed

**Before:** **From** in a new email could show the global default immediately or fail to update after you picked a process. Resolved tickets could still occupy an operator’s quota slot, so the queue filled slowly even when they were no longer working that case. A bad OAuth bind could leave an invalid mailbox entry and break the email channel. When webhook enrich failed on a call, auto-transcription could start with no assigned operator.

**Now:** **From** waits for a process and uses its mailbox. Dialog quota and auto-distribution ignore resolved ticket rooms without active work. Only valid mailbox addresses remain in `accounts`. Administrators choose behavior on enrich failure; if an operator is already assigned during call processing, auto-transcription uses them.

## Why It Matters

Fewer emails sent from the wrong department, faster queue fill without false “over limit” states, more stable email after connecting mailboxes, and predictable call handling when external webhook enrich is unavailable.
