1.3.0

What's Changed

New Features

• target_account_ids: Target specific AWS account IDs (must be 12 digits)
• account_filter_type: Control filtering behavior when both OUs and accounts are specified (INTERSECTION, UNION, DIFFERENCE, NONE)
• tags: Apply custom tags to StackSet and StackSet Instance resources
• stack_set_name: Customize the StackSet name to avoid naming conflicts

Account Targeting Modes

• Default: Deploy to all accounts in the organization (unchanged behavior)
• OU-only: Deploy to specific organizational units
• Combined: Use account_filter_type to control intersection, union, or difference logic

Implementation Details

• All new variables have safe defaults that preserve existing behavior
• account_filter_type is only set when both OUs and accounts are specified (prevents forced replacement)
• Enhanced README with comprehensive examples and use cases
• Input validation for account IDs (12-digit format) and filter types (enum)

Backwards Compatibility

• Fully backwards compatible - existing customers can upgrade without any changes to their configuration or infrastructure. All new variables are optional with defaults matching previous hardcoded behavior.
