Hello 🙂

I was wondering if it’s possible to show a notification for new updates in a swf file.

Like what if I upload a .txt file somewhere and inside it there’s a variable, something like;

```auto
newupdate="Version 2.0 is ready for download at domainname.com."

```

And this will show up in a text field somewhere in my swf file. Is this possible? Are there any pros and cons about using this method of notification?
