33Breaking Changes:
4- * Replaced ` .search_space ` and ` .search_spaces ` with the ` .gene ` macro-style method for defining genetic attributes.
4+ * Replaced legacy .search_space and .search_spaces definitions with the new .gene macro-style for defining genetic attributes.
55* Renamed ` #value ` to ` #fitness ` throughout the codebase for clarity.
66* Removed deprecated ` Gene.crossover ` in favor of ` Gene.combine ` .
77* Removed deprecated ` Evolution#crossover ` in favor of ` Evolution#combination ` .
88* Renamed ` Evolvable#after_initialize ` to ` Evolvable#after_initialize_evolvable ` .
99* Changed population initialization and evolvable creation workflow for more consistency.
10- * Simplified error handling in favor of more single ` Evolvable::Error ` type with more informative messages.
10+ * Simplified error handling by unifying all exceptions under a single Evolvable::Error type
1111* Changed ` Population#new_evolvables ` to only accept a ` count ` parameter, removing the ` evolvables ` parameter.
1212* Changed default ` size ` parameter in ` Population#initialize ` from 40 to 0.
1313* Changed ` Population#evolve ` default ` count ` parameter from ` Float::INFINITY ` to ` 1 ` .

1717* Introduced the ` Evolvable::GeneCluster ` module for complex gene grouping.
1818* Added ` Evolvable::Community ` for managing multiple populations and their interactions.
1919* Added genome merging capabilities with ` merge_genome! ` and ` load_and_merge_genome! ` .
20- * Improved inheritance support for evolvable classes, preserving gene configurations.
2120* Added ` evolve_selected ` method to Population for evolving a specific subset of evolvables.
22- * Added direct access to genes and gene clusters through automatically generated methods .
23- * Added new evolution API methods: ` evolve_to_goal ` and ` evolve_forever ` for more intuitive control over the evolution process .
21+ * Added automatic method generation for accessing genes and gene clusters by name .
22+ * Added new evolution control methods: evolve_to_goal and evolve_forever for more intuitive lifecycle control .
2423* Comprehensive YARD documentation and README overhaul.
