+### 🌻 Features
+
+- Godot 4.5 API level ([#1339](https://github.com/godot-rust/gdext/pull/1339))
+- Allow to use `#[func(gd_self)]` with Interface methods ([#1282](https://github.com/godot-rust/gdext/pull/1282))

+- 🌊 Numeric `#[export]` limits and type checks ([#1320](https://github.com/godot-rust/gdext/pull/1320))
+- 🌊 Argument passing: new `ToGodot::Pass` is either `ByValue`/`ByRef` ([#1285](https://github.com/godot-rust/gdext/pull/1285))
+- 🌊 More type-safe engine APIs (mostly int -> enum) ([#1315](https://github.com/godot-rust/gdext/pull/1315))

+- Migrate inherent `singleton()` fn to new `Singleton` trait ([#1325](https://github.com/godot-rust/gdext/pull/1325))
+
+### 📈 Performance
+
+- `base()` + `base_mut()` no longer clone `Gd` pointer ([#1302](https://github.com/godot-rust/gdext/pull/1302))
+- Restore `ToGodot` pass-by-ref for objects ([#1310](https://github.com/godot-rust/gdext/pull/1310))
+- Remove static lifetime in `StringName::from(&CStr)` ([#1307](https://github.com/godot-rust/gdext/pull/1307))
+- `AsArg` for objects now consistently passes by reference ([#1314](https://github.com/godot-rust/gdext/pull/1314))
+- 🌊 Argument passing: new `ToGodot::Pass` is either `ByValue`/`ByRef` ([#1285](https://github.com/godot-rust/gdext/pull/1285))
+- 🌊 Remove by-value `From` conversions between strings ([#1286](https://github.com/godot-rust/gdext/pull/1286))
+
+### 🧹 Quality of life
+
+- 🌊 Remove support for Godot 4.1 ([#1292](https://github.com/godot-rust/gdext/pull/1292))
+- `MultiplayerApi`: getters now use `&self` receiver rather than `&mut self` ([#1274](https://github.com/godot-rust/gdext/pull/1274))
+- `ClassName` construction from dynamic values ([#1298](https://github.com/godot-rust/gdext/pull/1298))
+- Implement Send and Sync for PhantomVar ([#1305](https://github.com/godot-rust/gdext/pull/1305))
+- Add `ClassCodegenLevel::Core` ([#1289](https://github.com/godot-rust/gdext/pull/1289))
+- 🌊 Merge `AsObjectArg<T>` into `AsArg<Gd<T>>` ([#1308](https://github.com/godot-rust/gdext/pull/1308))
+- 🌊 Add `SignedRange` for negative indices in range ops ([#1300](https://github.com/godot-rust/gdext/pull/1300))
+- 🌊 Require that classes starting with "Editor" be marked internal ([#1272](https://github.com/godot-rust/gdext/pull/1272))
+- Address `clippy::nursery` lint errors in macros ([#1317](https://github.com/godot-rust/gdext/pull/1317))
+- FFI: make `AsArg` internals safer to use ([#1321](https://github.com/godot-rust/gdext/pull/1321))
+- `AsArg` now supports `Option<DynGd>` ([#1323](https://github.com/godot-rust/gdext/pull/1323))

+- 🌊 Split `apply_deferred()` -> `run_deferred()` + `run_deferred_gd()` ([#1327](https://github.com/godot-rust/gdext/pull/1327))
+- 🌊 `StringName`: remove `From` impl for `&'static CStr` ([#1316](https://github.com/godot-rust/gdext/pull/1316))
+- 🌊 `Callable::from_local_fn()` now returns `R: ToGodot` ([#1332](https://github.com/godot-rust/gdext/pull/1332))
+- 🌊 Add higher-level `CallErrorType` for script instance APIs ([#1333](https://github.com/godot-rust/gdext/pull/1333))
+- 🌊 Remove deprecated symbols, other small cleanups ([#1340](https://github.com/godot-rust/gdext/pull/1340))
+- 🌊 `Callable::from_linked_fn` now returns `R: ToGodot` instead of Variant ([#1344](https://github.com/godot-rust/gdext/pull/1344))
+- `Callable`: rename `from_local_fn` -> `from_fn`, keep deprecated `from_local_fn` with old signature ([#1346](https://github.com/godot-rust/gdext/pull/1346))
+
