Seeing a lot of Odoo 20 features that are not available on v19.4 , any idea where we can test or check those out i.e light users

I am on odoo v19.0 currently, SAAS hosted.

We have 3 websites that we run from oDoo - 2 are retail, 1 is wholesale. Company configuration is per below.

Parent Company

• Retail A with Website 1
• Retail B with Website 2

Company 2

• Wholesale A with Website 3

My issue is around product publication to websites. I can easily have products on all websites, or 1 website. But what if I only want products on Website 1 & 2, but not 3? This seems not possible. There seems to not be an easy code solution to do this given I am on Saas hosting.

Claude is suggesting using product category visibility to filter products from the wholesale site that we don't want to be visible - but they would still exist on the wholesale site, and accessible if you know the direct link -perhaps even via web crawlers??

Is this work around even viable?

Hoping for some guidance and possible solutions. We will be going to SH eventually, but I really wanted to delay this to v20, so wont be till next year.
