Parameter naming in POST data changed

Looks like some parameters in in post data have received new names.

The birthday field now comes with fieldnameday, fieldnamemonth and fieldnameyear, before it was fieldname[1],fieldname[2] or something like that.

Looks like the same happend to name and address fields. I receive now ...street.., ...city...

We received more than 5000 form submissions until last week, now the parameter's names have changed and I don't know why.

How can I get back to the previous naming convention? Do I have to change the web hook?

Yes, you might need to change the parameters in the webhook,  probably these changed if you updated the form or performed a majot change

I didn't change anything. The parameter names changed without any interaction from my side.

The parameter naming has been restored. I tested and everything works like before. No need to change my webhook. I could re-submit all yesterday's form submissions sucessfully now.

Thanks for whatever you've done.
