Title: A new major release, with these significant changes:<p><pre><code>  - cp has changed how it handles data
    - enables CoW by default (through FICLONE ioctl),
    - uses copy offload where available (through copy_file_range),
    - detects holes differently (though SEEK_HOLE)
    - This also applies to mv and install.

  - utilities are more tuned to the hardware available
    - wc uses avx2 instructions to count lines
    - cksum uses pclmul instructions for --algorithm=crc
      - Other digest tunings remain delegated to libcrypto

  - More amalgamation of utilities
    - cksum now supports the -a option to select any digest.
    - This is the preferred interface, rather than sha*sum etc.
    - This is similar to the amalgamation of encoding utilities
      introduced in the basenc command in v8.31.
