This does not yet work for VST3. You'll always get empty slices there.

# Breaking changes
Since there is no stable release yet, there is also no proper changelog yet. But
since not everyone might want to dive through commit messages to find out what's
new and what's changed, this document lists all breaking changes in reverse
chronological order. If a new feature did not require any changes to existing
code then it will not be listed here.
## [2022-05-2y]
- The `Plugin::initialize()` method now takes a `&mut impl InitContext` instead
of a `&mut impl ProcessContext`.
- `Plugin::process()` now takes a new `aux: &mut AuxiliaryBuffers` parameter.
This was needed to allow auxiliary (sidechain) inputs and outputs.
## [2022-05-22]
- Previously calling `param.non_automatable()` when constructing a parameter
also made the parameter hidden. Hiding a parameter is now done through
`param.hide()`, while `param.non_automatable()` simply makes it so that the
parameter can only be changed manually and not through automation or
modulation.
- The current processing mode is now stored in `BufferConfig`. Previously this
could be fetched through a function on the `ProcessContext`, but this makes
more sense as it remains constant until a plugin is deactivated. The
`BufferConfig` now contains a field for the minimum buffer size that may or
may not be set depending on the plugin API.
