The email I got said this:

>What is important after the changeover? • We want to be able to offer you even better customer service in the future. For that reason, we want to change the date of your invoice. This will make it easier for us to quickly answer questions about your invoices. Starting in April, your new permanent billing day will be the 12. of the month.

I think they have just spread the billing day out across the month for all customers
