# Release 5.3.38

## What changed

This release strengthens **Scenario Builder** (connectors, large imports, keyboard edits, publish flow), refreshes **Block Search** in the constructor, adds **clickable links in file messages** in the operator experience, and improves **system behaviour under load**. Together with earlier 5.3.x changes in the same line, operators get a more predictable editor and dialog experience.

- Safer handling of scenario connectors so graphs stay valid after save and conversion.
- Faster, more reliable import of **large** scenarios.
- When you remove **keyboard** buttons, linked transitions stay consistent more often.
- **Block Search:** history of searches, clearer results, movable search window, and translated UI strings.
- **File messages:** links in related message text become clickable where applicable.
- **Broadcast / entry flows:** routing after certain alias and entry steps is more predictable — worth a quick retest of important campaigns.
- **Stability:** better handling of busy periods (queues and retries).

## How it changed

**Previously**, very large scenario imports or complex connector/keyboard edits could occasionally leave broken links, timeouts, or unclear publish errors; file messages did not always expose URLs as clickable links; heavy load could surface retries without backoff.

**Now**, imports remap nodes more efficiently, connector conversion follows stricter safety rules, keyboard edits remap edges, Block Search is easier to use repeatedly, URLs in file-message context are easier to open, and the system limits repeat attempts and spaces them with short delays during busy periods.

**Why it matters:** teams that maintain large bots spend less time recovering broken scenarios and get clearer feedback when something fails; operators work faster in dialogs and editors.
