Release v0.17.0

What's New

Features

• Window-level focus — focus: true on a window selects it after session creation (#366)

Improvements

• Session/pane validation refactored — cleaner SRP-based validation with count_matching_panes and validate_exclusive_pane_property (#368)
• Migrated from serde_yaml to noyalib — serde_yaml is archived/unmaintained; noyalib is YAML 1.2 compliant, actively maintained, zero unsafe code (#369)
• Removed serde_valid — was dead weight (no validation attributes used) (#369)

Maintenance

• Deduplicated flake-parts inputs in rustnix (#367)
• Updated all cargo dependencies
• Flake lock updates

Breaking

• YAML 1.2 strict booleans: bare YES/NO/on/off are now parsed as strings, not booleans. Use true/false instead.
