Do Dropbox Standard, Advanced, and Professional still exist?

Hello! Does Dropbox Standard, Advanced, and Professional still exist? 
Dropbox Business used to have:

• Business Standard for $18/month or $15/month for the yearly plan for 5TB.
• Business Professional for $19.99/month or $16.58/month for the yearly plan for 3TB.
• Business Advanced for $30/month or $24/month for the yearly plan for 3TB

But now, I can't find it in their website. I'm currently writing an article about Dropbox Business, so any information on when they renewed their plans would be extremely helpful.
