At first, I had a hard time figuring out, what exactly you meant with your question... until on YT I found a video by JavaJim mentioning the "new" water tank (as well as some other "improvements", like the new steam and hot water valves, which apparently were upgraded in April 2021).
Well, this may be true for the US and/or Canada; here in Europe, these upgrades have been there for a longer time; my Bianca, ordered January 2021 was already equipped with these "April 2021 updates".

Yes, I ordered in June 2021 and received the watertank with the logo on the front and the black rubber inserts. That‘s what u meant, right?
