15021	btrfs-progs-5.12	pierre	Bruce Dubbs	"btrfs-progs version 5.12 have been released.

Notable things:

* libbtrfsutil has been relicensed to LGPL v2.1+

* zoned mode support has been added
  * a host-managed device is needed, there are several options how to emulate
    such device (null_blk, TCMU runner, file-backed ZBC device)
  * kernel 5.12+ is needed, during my testing I've hit a lot of bugs or corner
    cases so we're entering the stabilization period
  * https://btrfs.wiki.kernel.org/index.php/Zoned intro, will be updated as
    things get discovered

* travis-ci integration has been disabled, I'd like to find another hosted CI
  but so far none provides a recent kernel so more tests won't pass, last option
  is to self-host some VMs and monitor git, getting just build tests works but
  we need to run the testsuite
