# Release 5.4.0

## What changed

- **Saved filters in Operator Line:** **customer rating (CSAT)** conditions save and apply reliably together with other conversation search criteria.
- **Instagram (Meta):** broader **scenario automation** in the channel — easier responses and actions after events in **Meta**.
- **Merged tickets:** clearer limits and hints when a ticket was **merged** into another — less confusion about connecting and participants.
- **Ticket status in Operator Line:** you can **pick the ticket status** in the conversation context and open new rooms linked to the ticket more reliably.
- **Mailgun email:** after **soft-deleting** an email account you can **connect again** without the old state blocking you.
- **Constructor UI theme:** switch between **light and dark** theme in the constructor and related screens.

## How it changed

**Previously**, CSAT in saved filters could behave inconsistently, Instagram scenarios did not cover every case, merged tickets sometimes looked like normal tickets for connection, ticket status was less convenient from the line, reconnecting Mailgun after deletion could get stuck, and only the light look was effectively standard.

**Now**, filters with ratings are more stable, **Meta** automation is more flexible, **merged** ticket UX is clearer, ticket status in **Operator Line** is easier to manage, **Mailgun** can be brought back after soft delete, and the constructor UI can match comfort preferences.

**Why it matters:** faster searches by service quality, fewer manual workarounds for Instagram support, fewer mistakes with merged tickets, smoother email operations, and more comfortable long sessions.
