# Upgrade guide for Scheduler v4.1.4

## `eventKeyDown` & `eventKeyUp` event signatures changed

Simple renaming of the event params fired by Scheduler when pressing a key with events selected. The event always
passes an array of `eventRecords` and `assignmentRecord`:

**Old code:**

```javascript
new Scheduler({
    listeners : {
        eventKeyDown : ({ eventRecord, assignmentRecord }) => { /*...*/ }
    }
})
```

**New code:**

```javascript
new Scheduler({
    listeners : {
        eventKeyDown : ({ eventRecords, assignmentRecords }) => { /*...*/ }
    }
})
```
