A new major release, with these significant changes:
- 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.
