[Compare
Source](https://redirect.github.com/BLAKE3-team/BLAKE3/compare/1.6.0...1.6.1)

version 1.6.1

Changes since 1.6.0:

-   Remove `mmap` from the default features list. It was added
    accidentally in v1.6.0, last week. This is technically a
backwards-incompatible change, but I would rather not tag v2.0.0 for a
    build-time bugfix with a simple workaround.
