v1.6.0

Release v1.6.0

This release adds jump host configuration support in config.yaml and improves SSH config integration.

New Features

• Jump Host Configuration Support in YAML (Issue #115, PR #120)
  • Global defaults level: defaults.jump_host for all clusters
  • Cluster level: clusters.<name>.jump_host for cluster-specific settings
  • Node level: Per-node jump_host in detailed node configuration
  • Environment variable expansion supported (${VAR} or $VAR syntax)
  • Empty string ("") explicitly disables jump host inheritance
  • CLI -J option always takes precedence over configuration

Improvements

• SSH Config ProxyJump Directive (Issue #117, PR #119)
  • ProxyJump directive from SSH config now properly applied when -J option not specified
  • Priority order: CLI -J > config.yaml jump_host > SSH config ProxyJump
• Documentation Improvements
  • Added comprehensive jump_host configuration documentation to README.md
  • Updated docs/architecture/ssh-jump-hosts.md with detailed architecture
  • Updated example-config.yaml with all jump_host configuration patterns

Bug Fixes

• Jump Host Authentication (Issue #116, PR #118)
  • Properly handle empty SSH agent when authenticating through jump hosts
  • Fall back to key-based authentication when agent has no identities
• Config Fallback (PR #120)
  • Environment variables now properly expanded in jump_host values via expand_env_vars
  • Configuration jump_host properly used in exec and interactive modes
• Jump Host Error Messages - Improved authentication error messages and documentation

CI/CD Improvements

• Updated GitHub workflows

Technical Details

• Added ConfigResolver::resolve_jump_host() method for centralized jump host resolution
• Jump host priority: CLI > Node > Cluster > Global defaults
• Comprehensive test coverage: 424 lines of tests for jump_host configuration
• Integration tests for all priority levels and edge cases
