Version 2.56.1
==============

- The minimum supported Rust version (MSRV) is 1.65.  Unfortunately
  the assert_cmd crate, used in the test suite, bumped its MSRV and is
  forcing us to do the same.

- #965 - Shrink the shared library by telling the linker to omit
  unused code (Sebastian Dröge).

- Updates to dependencies (Lukáš Tyrychtr, Kalev Lember).
