.863 should now be live. Went live somepoint in the last few days. I didn't know until someone on twitter said that 24H2 was being released again to Release Preview channel for client with new update. (https://blogs.windows.com/windows-insider/2024/05/22/releasing-windows-11-version-24h2-to-the-releas...) Client 24H2 has the same codebase as Server 2025 so Server has also received .863. Should be available now on Windows Update. Its showed up on my server and installed fine.
