[Compare Source](https://github.com/jaraco/keyring/compare/v23.7.0...v23.8.0)

-   [#&#8203;448](https://github.com/jaraco/keyring/issues/448): `SecretService` and `libsecret` backends now support a
    new `SelectableScheme`, allowing the keys for "username" and
    "service" to be overridden for compatibility with other schemes
    such as KeePassXC.

-   Introduced a new `.with_properties` method on backends to
    produce a new keyring with different properties. Use for example
    to get a keyring with a different `keychain` (macOS) or
    `scheme` (SecretService/libsecret). e.g.::

    keypass = keyring.get_keyring().with_properties(scheme='KeePassXC')

-   `.with_keychain` method on macOS is superseded by `.with_properties`
    and so is now deprecated.
