---

• mkfs:
  • use GET_CSUMS ioctl (if provided by kernel, 7.2) to reuse existing checksums for --rootdir, works with --reflink to avoid reading file data
  • fix last block handling for reflink
  • fix handling of incompressible data extents
  • fix --rootdir size estimation when using hardlinks
• fix mkswapfile: add option to specify page size, useful on ARM64
• check: add option to skip qgroup verification to speed up check
• in experimental build, use V2 of tree search ioctl, this can use larger buffer
• preliminary fscrypt support
• enhance filesystem opening modes with more fine-grained support of partially damaged trees and allow to skip non-essential trees
• other:
  • stability and error handling fixes
  • CI updates
  • updated tests
  • documentation updates
