 Another API change between v2 and v3 is that the notion of a default feature set has gone away: you must now specify explicitly which crate-supported keystores you want included (other than the `mock` keystore, which is always present). So all keyring client developers will need to update their `Cargo.toml` file to use the new features correctly.

+All v2 data is fully forward-compatible with v3 data; there have been no changes at all in that respect. _However_, unlike v2, the v3 implementation of the secret service credential store will _not_ read credentials that were written by the v1 keyring. (For details about why this decision was made, see [this issue](https://github.com/hwchen/keyring-rs/issues/204)). Keyring clients who use the secret service and are still using old v1 credentials should replace those credentials with v2/v3 credentials. The CLI has been extended to allow reading and deleting v1 credentials (and thus provides sample code for how to do this).
 
 The MSRV has been moved to 1.75, and all direct dependencies are at their latest stable versions.
