Today i updated a 0.20 version to the newest.  
All went well until i started testing my script.  
I stored data with a point in the name "msg.client" in the past this was working but now it doesnt.  
is that a setting thing or new way of working?  
Just a little scared now to update another 45 pi's

Hi @RogierQ

can you be a little more specific? How are you storing the data?

Sure!  
What i did was  
global.set(“msg.client”,client);  
Were client was an object  
In the new version it was in the context saved as “msg” and returned as object of object client if i say it correct. Still learning objects and array and things

I thought we always treated keys like `msg.client` as the `client` property of the object `msg`... so I'm slightly surprised it appears to have changed for you.

But yes, keys with `.` in them are treated as being multi-level objects.

Can you tell me a little more about multi level objects?  
When i google it i do not understand what it exactly means  
O do you have a link to a good explanation?  
Thanks!

When it sees a key with the value `"msg.client"`, rather than treat that as a single identifier, it splits it up to be the `client` property of the `msg` object. In exactly the same way as it would when you use something like `msg.client` in regular JavaScript code.

For example, if you did:

```auto
global.set("msg.client", "123");

```

You end up with an object called `msg` with a property called `client` and a value of `"123"`:

```auto
{
   msg: {
      client: "123"
   }
}

```
