---------------------

(no changes yet)

.. _0.3.1: https://github.com/trezor/python-shamir-mnemonic/compare/v0.3.0...HEAD

---------------------

Incompatible
~~~~~~~~~~~~

- The `shamir` command no longer works out of the box. It is necessary to install the
`cli` extra while installing the package. See README for instructions.

Added
~~~~~

- Added BIP32 master extended private key to test vectors.
- Added support for extendable backup flag.

Changed
~~~~~~~

- The `shamir_mnemonic` package now has zero extra dependencies on Python 3.7 and up,
making it more suitable as a dependency of other projects.
- The `shamir` CLI still requires `click`. A new extra `cli` was introduced to handle
this dependency. Use the command `pip install shamir-mnemonic[cli]` to install the CLI
dependencies along with the package.

Removed
~~~~~~~

- Removed dependency on `attrs`.
