 ## Unreleased
 
+- Added initial supported for Python objects [#31](https://github.com/metadsl/egglog-python/pull/31)
+
+  - Renamed `BaseExpr` to `Expr` for succinctness
+  - Add [slides for zoom presentation with Open Teams](explanation/2023_07_presentation)
+  - Started adding [tutorial for using with array API and sklearn](tutorials/array-api), using this to drive
+    the support for more Python integration
+  - Added a PyObject sort with the `save_object` and `load_object` egraphs methods and the `exec`
+  - Added more general mechanism to upcast Python arguments into egglog expressions, by registering `converter`s
+  - Added support for default arguments (this required refactoring declerations so that pretty printing can lookup expressions)
+  - Added support for properties
+  - Added support for passing args as keywords
+  - Add support for pure Python methods, using the `preserve` kwarg to implement functions like `__bool__` on expressions.
+  - Fix `__str__` method when pretty printing breaks.
+  - Added to/from i64 to i64 methods.
+  - Upgraded `egg-smol` dependency ([changes](https://github.com/saulshanabrook/egg-smol/compare/353c4387640019bd2066991ee0488dc6d5c54168...2ac80cb1162c61baef295d8e6d00351bfe84883f))

 - Fix bug calling methods on paramterized types (e.g. `Map[i64, i64].empty().insert(i64(0), i64(1))`)
 - Fix bug for Unit type (egg name is `Unit` not `unit`)

+- Use `@class_` decorator to force subclassing `Expr`
 - Workaround extracting definitions until [upstream is fixed](https://github.com/egraphs-good/egglog/pull/140)
 - Rename `Map.map_remove` to `Map.remove`.
 - Add lambda calculus example
