 ## UNRELEASED
 
-- Add WIP `egglog.exp.any_expr` code for tracing arbitrary expressions with Python fallback.
-- BREAKING: Remove suport for Python 3.11 now that pyo3 has dropped support.
-- Allow mutating methods to update their underlying expression via `Expr.__replace_expr__`, and ensure default rewrites return the mutated receiver when using `mutates_self` or `mutates_first_arg`.
-- BREAKING: Store `PyObject` values as `cloudpickle` bytes instead of live references so duplicates merge by value; `.value` now returns a fresh copy and the sort accepts objects like `None` that previously failed.
-- Adds a `__call__` method (and `call_extended` for kwargs) to `PyObject` to replace `py_eval_fn`, which is now deprecated.
-- Improve doctest support, teaching expressions about their `__module__`, `__dir__`, and special methods.
-- Surface original Python exceptions from the runtime and tighten pretty-printing of values that cannot be re-parsed to make debugging e-graph executions easier.
-- Update the bundled Egglog crate, visualizer, and related dev dependencies (including `ipykernel`) to pick up the latest backend fixes.
