# PathOptions
This release introduces PathOptions, a powerful new feature that enables precise control over how different parts of your JSON/YAML data are compared. PathOptions allow you to apply different comparison semantics to specific paths within your data structures, giving you fine-grained control over diff behavior.

Key Features:
- Targeted comparison options: Apply SET, MULTISET, precision, or setkeys options to specific paths using the syntax `{"@":["path","to","target"],"^":[options]}`
- Path isolation: Options only affect their specified paths and don't leak globally, allowing you to mix different comparison semantics in the same diff
- Enhanced array dispatch: Fixed critical bug where PathOptions with empty paths (root level) weren't being applied correctly for array dispatch
- Comprehensive documentation: Complete v2 Diff Language guide with new EBNF grammar, PathOption integration examples, and updated CLI help showing flag equivalents
- Extensive test coverage: Added 24 test cases demonstrating PathOption functionality across various data structures and edge cases

Examples:
### Apply SET semantics to specific array while others remain lists:

jd -opts='[{"@":["tags"],"^":["SET"]}]' a.json b.json

### Multiple PathOptions with different semantics

jd -opts='[{"@":["items"],"^":["SET"]}, {"@":["price"],"^":[{"precision":0.01}]}]' a.json b.json

This release maintains full backward compatibility while adding powerful new capabilities for sophisticated diff control scenarios.
