1.3.0

Added

• Automatic retry mechanism for failed downloads (3 attempts, 5s delay)
• Atomic operations - all lists fetched before applying any nftables changes
• Centralized error handling and validation via fetch_all_lists()
• Enhanced logging and error messages

Fixed

• Inconsistent firewall state after network failures during reload (#13, thanks @chenbihao)

Changed

• Refactored blacklist_sets() and country_sets() to accept pre-fetched data
• Operations abort with exit code 1 on download failures (prevents inconsistent state)
