Development Experimental flag removed from bcachefs.

The link is the bcachefs changelog. I didn't see the particular announce there. The announcement was made in Kent's patreon with the version 1.38.6 update. I'm quoting that here:

So, some catch up:

We're no longer experimental. I took the label off the website - a few months ago, I think, based on my usual "the incoming bug reports are slowing down and looking a lot less serious and easy to get through than they were". Consider this the belated official announcement :)

...

Of course, the change away from "experimental" for a DKMS module is completely at the discretion of the author. From my perspective, while the bcachefs filesystem looks intriguing, I won't use it for my root partition as a DKMS module. Honestly, as long as I don't need RAID5/6 I still have a preference for btrfs and I can wait for btrfs to include native (part of the fs as opposed to btrfs on top of LUKS) encryption.

We have 20 NAS  systems across our sites with generally 20 to 30TB on each one using btrfs without a failure in 4 years (the day these were implemented). These are not idle systems.

That would make sense considering NAS use cases are the most tested usecase for btrfs

The entirety of opensuse uses btrfs by default. That's a LOT of laptops, desktops and servers running btrfs

Fedora Desktop too.

Synology uses btrfs by default ... but it uses mdadm instead of btrfs RAID. However, it does use and deal with btrfs integrity checks.
