v0.3.0 - minor API cleanups, as suggested by pedantic clippy lints - generation of manpages and shell completions has been rewritten in `xtask` style - improvements to the documentation - switched logging to the `tracing` crate but the `log` integration is present via `tracing` shim - the CLI uses different exit codes depending on the error - better manpages, mostly automatically generated from documentation and code - document signing and signatures
