- ActiveRecord querying & preloading — refactored the preloader for performance, fixed duplicate record handling, implemented
pluck, and improved#lastto leverage SQL-level ordering. - Association handling — fixed counter cache calculation bugs, foreign key replacement in inverse associations, and collection association creation methods.
- ActiveSupport callbacks — extensively refactored the callback system, removing dead code, deprecating legacy options, and simplifying/optimizing logic.
Overall focus: code quality, performance, and bug fixes rather than new feature work.
