No ReFS option in 29641
When install OS using the ISO image of this new build, there is no ReFS filesystem selection as in build 29621, is there any change in Windows setup?
This is a known issue and will be fixed in an upcoming Insider preview build. I will share the build number as soon as it's confirmed. In the meantime as a workaround, you may also use setup unattend to configure ReFS boot on your systems: ReFS Boot Volume Setup for Windows Server (preview) | Microsoft Learn

You can still format the system volume with REFS using DISKPART. Hit Create Partition to have Windows create the three GPT partitions. Press <SHIFT><F10> to enter Command Prompt. Enter DISKPART. Select disk 0 (assuming that is your disk), select part 3, format fs=refs quick.

I wondered the same several builds ago. I don't know if something has indeed changed, but the installer is so good at hiding "at which point can I select the filesystem?", and I failed once because I deleted the Recovery partition (WinRE), thinking I don't need specific recovery features – realising only after a couple of installations that yeah I had to let Windows create that 2 GB partition and I had to leave it alone for ReFS to be an option. Now to try to remember at which point that partition got created... only after clearing the whole medium? I wish there just a separate "Create recovery partition (mandatory for ReFS)" button.
Did you check the prerequisites/Limitations?
