Hi @bers,
Thank you for bringing my attention to this, you are right. The product roadmaps are accessible publicly only through our Productboard portals. This is where you can subscribe to future updates, vote, and provide feedback to help us improve the product. The C++23 support card can be seen here.
Also, since our move to Atlassian cloud, we, unfortunately, are no longer able to allow community users to watch or subscribe to issues.
Best regards,
Michael
