I wondered about this too. I didn't see any changes so I wondered if they updated the paid subscribers first? I paid for a while last year but didn't see the need so I cancelled.
You may want to count your blessings. The new version is awful, in my (and many others) opinions. I’m hanging on to my old version as long as I possibly can.
I strongly suggest yo do not upgrade. Most users here find the upgrade a (huge) step backwards. You will need to turn off auto-update in the Play Store or you will get the new version whether you want it or not.
