If you see errors about `getiter` and/or `iternext` then also see #8813.
In order to save space, the `getiter` and `iternext` slots were merged on `mp_obj_type_t`. The following changes need to be made to your object type definitions.
In order to save space, the `getiter` and `iternext` slots were merged on `mp_obj_type_t` into a single new slot `iter`. The following changes need to be made to your object type definitions.
- If you previously had just a `getiter`, then no change is required.
- If you had `getiter` as `mp_identity_getiter` and a custom `iternext`, then pass your iternext function to the `getiter` slot, and set the `MP_TYPE_FLAG_ITERNEXT` flag.
- If you had `getiter` as `mp_identity_getiter` and `mp_stream_unbuffered_iter` as `iternext`, then just set the `MP_TYPE_FLAG_ITERNEXT_STREAM` and do not set the `getiter` slot.
- If you had both a custom getiter and iternext, then you need to pass an instance of a `mp_getiter_iternext_custom_t` to the `getiter` slot and set the `MP_TYPE_FLAG_ITERNEXT_CUSTOM` flag. See [moduasyncio.c](https://github.com/micropython/micropython/blob/master/extmod/moduasyncio.c).
