End of life for version 6.3

What long hibernate 6.3 will be actively supported along with end of commercial support.

There is no commercial support for Hibernate ORM 6.3, only for Hibernate ORM 6.2 through subscriptions of JBoss EAP 8 or RHBQ (Red Hat build of Quarkus) version 3.2.
Community support will be stopped for ORM 6.3 as soon as 6.4.0.Final is released.

Thanks, Any idea when 6.4.0 will be available?

We just released 6.4.0.CR1 a few hours ago. The final release will be available in the coming weeks.
