## 0.28.0

### `handle_user_collection_request` returns `bool`

```admonish tldr
`memory_manager::handle_user_collection_request` now returns a boolean value to indicate whether a GC
is triggered by the method or not. Bindings may use the return value to do some post-gc cleanup, or
simply ignore the return value.
```

API changes:

- module `memory_manager`
+ `handle_user_collection_request` now returns `bool` to indicate if a GC is triggered by the method.
Bindings may use the value, or simply ignore it.
