# 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.
|
|
|
|
## [2022-08-19]
|
|
|
|
- `Plugin::DEFAULT_NUM_INPUTS` and `Plugin::DEFAULT_NUM_OUTPUTS` have been
|
|
renamed to `Plugin::DEFAULT_INPUT_CHANNELS` and
|
|
`Plugin::DEFAULT_OUTPUT_CHANNELS` respectively to avoid confusion as these
|
|
constants only affect the main input and output.
|
|
- Standalones now use the plugin's default input and output channel counts
|
|
instead of always defaulting to two inputs and two outputs.
|
|
|
|
## [2022-07-18]
|
|
|
|
- `IntRange` and `FloatRange` no longer have min/max methods and instead have
|
|
next/previous step methods. This is for better compatibility with the new
|
|
reversed ranges.
|
|
|
|
## [2022-07-06]
|
|
|
|
- The block smoothing API has been reworked. Instead of `Smoother`s having their
|
|
own built-in block buffer, you now need to provide your own mutable slice for
|
|
the smoother to fill. This makes the API easier to understand, more flexible,
|
|
and it allows cloning smoothers without worrying about allocations.In
|
|
addition, the new implementation is much more efficient when the smoothing
|
|
period has ended before or during the block.
|
|
- There are new `NoteEvent::PolyModulation` and `NoteEvent::MonoAutomation`
|
|
events as part of polyphonic modulation support for CLAP plugins.
|
|
|
|
## [2022-07-05]
|
|
|
|
- The `ClapPlugin::CLAP_HARD_REALTIME` constant was moved to the general
|
|
`Plugin` trait as `Plugin::HARD_REALTIME_ONLY`, and best-effort support for
|
|
VST3 has been added.
|
|
|
|
## [2022-07-04]
|
|
|
|
- There is a new `NoteEvent::Choke` event the host can send to a plugin to let
|
|
it know that it should immediately terminate all sound associated with a voice
|
|
or a key.
|
|
- There is a new `NoteEvent::VoiceTerminated` event a plugin can send to let the
|
|
host know a voice has been terminated. This needs to be output by CLAP plugins
|
|
that support polyphonic modulation.
|
|
- Most `NoteEvent` variants now have an additional `voice_id` field.
|
|
- The `CLAP_DESCRIPTION`, `CLAP_MANUAL_URL`, and `CLAP_SUPPORT_URL` associated
|
|
constants from the `ClapPlugin` are now optional and have the type
|
|
`Option<&'static str>` instead of `&'static str`.
|
|
|
|
## [2022-07-02]
|
|
|
|
- The `Params::serialize_fields()` and `Params::deserialize_fields()` methods
|
|
and the `State` struct now use `BTreeMap`s instead of `HashMap`s so the order
|
|
is consistent the plugin's state to JSON multiple times. These things are part
|
|
of NIH-plug's internals, so unless you're implementing the `Params` trait by
|
|
hand you will not notice any changes.
|
|
|
|
## [2022-06-01]
|
|
|
|
- The `ClapPlugin::CLAP_FEATURES` field now uses an array of `ClapFeature`
|
|
values instead of `&'static str`s. CLAP 0.26 contains many new predefined
|
|
features, and the existing ones now use dashes instead of underscores. Custom
|
|
features are still possible using `ClapFeature::Custom`.
|
|
|
|
## [2022-05-27]
|
|
|
|
- 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.
