readded changelog
- Removed legacy `ImGuiDragDropFlags` from `legacy.rs`, which were accidentally not cleared when they were remade in `drag_drop.rs` in v0.7.0.
+- Most tokens through the repository (eg. `WindowToken`, `TabBarToken`, `FontStackToken`, etc) now allow for permissive dropping -- i.e, you don't need to actually call the `.end()` method on them anymore. In exchange, these tokens have taken on a lifetime, which allows them to be safe. This could make some patterns impossible. Please file an issue if this causes a problem.
+- `end()` no longer takes `Ui`. This is a breaking change, but hopefully should be trivial (and perhaps nice) for users to fix. Simply delete the argument, or add a `_` before the token's binding name and allow it to be dropped on its own.
+
+- `PopupModal`'s `new` was reworked so that it didn't take `Ui` until `build` was called. This is a breaking change if you were invoking it directly. Simply move your `ui` call to `build` or `begin`.
