 - Added `reactpy.reactjs.component_from_string` to import ReactJS components from a string.
 - Added `reactpy.reactjs.component_from_npm` to import ReactJS components from NPM.
 - Added `reactpy.h` as a shorthand alias for `reactpy.html`.
+- Added `reactpy.config.REACTPY_MAX_QUEUE_SIZE` to configure the maximum size of all ReactPy asyncio queues (e.g. receive buffer, send buffer, event buffer) before ReactPy begins waiting until a slot frees up. This can be used to constraint memory usage.

 - `reactpy.types.VdomDictConstructor` has been renamed to `reactpy.types.VdomConstructor`.
 - `REACTPY_ASYNC_RENDERING` can now de-duplicate and cascade renders where necessary.
 - `REACTPY_ASYNC_RENDERING` is now defaulted to `True` for up to 40x performance improvements in environments with high concurrency.
+- Events now support debounce, which can now be configured per event with `event.debounce = <milliseconds>`. Note that `input`, `select`, and `textarea` elements default to 200ms debounce.

 - Fixed a bug where script elements would not render to the DOM as plain text.
 - Fixed a bug where the `key` property provided within server-side ReactPy code was failing to propagate to the front-end JavaScript components.
 - Fixed a bug where `RuntimeError("Hook stack is in an invalid state")` errors could be generated when using a webserver that reuses threads.
+- Fixed a bug where events on controlled inputs (e.g. `html.input({"onChange": ...})`) could be lost during rapid actions.
 - Allow for ReactPy and ReactJS components to be arbitrarily inserted onto the page with any possible hierarchy.
