v0.3.0

0.3.0 - 2025-11-11

💥 BREAKING CHANGES

• (optim, tree_utils) revamp Objective and flatten mechanics - 24ce7ee by @liblaf
• (core) The internal structure and inheritance of Objective and LinearOperator have changed. Classes that directly subclassed Objective or LinearOperator, or accessed their internal _flatten, unflatten, _jit, _timer, _args, _kwargs attributes directly, may need to be updated. The public API for assigning and calling function attributes (e.g., obj.fun) should largely remain compatible through FunctionDescriptor's __get__ and __set__ magic methods, but direct property access or internal introspection will be affected. - 91c77e0 by @liblaf
