# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic
Versioning](https://semver.org/spec/v2.0.0.html).
Since there is no stable release yet, the changes are organized per day in
reverse chronological order. The main purpose of this document in its current
state is to list breaking changes.
## [2023-02-28]
### Breaking changes
- `ViziaState::from_size()` now takes a third boolean argument to control
whether the window's size is persisted or not. This avoids a potential bug
where an old window size is recalled after the plugin's GUI's size has changed
in an update to the plugin.
## [2023-02-20]
### Breaking changes
- The way audio IO layouts are configured has changed completely to align better
with NIH-plug's current and future supported plugin API backends. Rather than
defining a default layout and allowing the host/backend to change the channel
counts by polling the `Plugin::accepts_bus_config()` function, the plugin now
explicitly enumerates all supported audio IO layouts in a declarative fashion.
This change gives the plugin more options for defining alternative audio port
layouts including layouts with variable numbers of channels and ports, while
simultaneously removing ambiguities and behavior that was previously governed
by heuristics.
All types surrounding bus layouts and port names have changed slightly to
accommodate this change. Take a look at the updated examples for more details
on how this works. The `Plugin::AUDIO_IO_LAYOUTS` field's documentation also
contains an example for how to initialize the layouts slice.
- As a result of the above change, NIH-plug's standalones no longer have
`--input` and `--output` command line arguments to change the number of input
and output channels. Instead, they now have an `--audio-layout` option that
lets the user select an audio layout from the list of available layouts by
index. `--audio-layout=help` can be used to list those layouts.
## [2023-02-01]
### Breaking changes
- The `Vst3Plugin::VST3_CATEGORIES` string constant has been replaced by a
`Vst3Plugin::VST3_SUBCATEGORIES` constant of type `&[Vst3SubCategory]`.
`Vst3SubCategory` is an enum containing all of VST3's predefined categories,
and it behaves similarly to the `ClapFeature` enum used for CLAP plugins. This
makes defining subcategories for VST3 plugins easier and less error prone.
## [2023-01-31]
### Breaking changes
- NIH-plug has gained support MIDI SysEx in a simple, type-safe, and
realtime-safe way. This sadly does mean that every `Plugin` instance now needs
to define a `SysExMessage` type definition and constructor function as Rust
does not yet support defaults for associated types (Rust issue
[#29661](https://github.com/rust-lang/rust/issues/29661)):
```rust
type SysExMessage = ();
```
- As the result of the above change, `NoteEvent` is now parameterized by a
`SysExMessage` type. There is a new `PluginNoteEvent<P>` type synonym that can
be parameterized by a `Plugin` to make using this slightly less verbose.
## [2023-01-12]
### Breaking changes
- The Vizia dependency has been updated. This updated version uses a new text
rendering engine, so there are a couple breaking changes:
- The names for some of Vizia's fonts have changed. The constants and font
registration functions in `nih_plug_vizia::assets` and
`nih_plug_vizia::vizia_assets` still have the same name, but all uses of the
`font` CSS property and `.font()` view modifier will have to be changed.
- Metrics for rendered text have change slightly. Most notably the height and
vertical positioning of text is slightly different, so you may have to
adjust your layout slightly accordingly.
## [2023-01-11]
### Breaking changes
- `Editor::param_values_changes()` is no longer called from the audio thread and
thus no longer needs to be realtime safe.
- A new `Editor::param_value_changed(id, normalized_value)` method has been
added. This is used to notify the plugin of changes to individual parameters.
- A similar new `Editor::param_modulation_changed(id, modulation_offset)` is
used to inform the plugin of a parameter's new monophonic modulation offset.
## [2023-01-06]
### Breaking changes
- The threads used for the `.schedule_gui()` and `.schedule_background()`
methods are now shared between all instances of a plugin. This makes
`.schedule_gui()` on Linux behave more like it does on Windows and macOS, and
there is now only a single background thread instead of each instance spawning
their own thread.
## [2023-01-05]
### Breaking changes
- `Buffer::len()` has been renamed to `Buffer::samples()` to make this less
ambiguous.
- `Block::len()` has been renamed to `Block::samples()`.
## [2022-11-17]
### Breaking changes
- The `Params` derive macro now also properly supports persistent fields in
`#[nested]` parameter structs. This takes `#[nested(id_prefix = "...")]` and
`#[nested(array)]` into account to allow multiple copies of a persistent
field. This may break existing usages as serialized field data without a
matching preffix or suffix is no longer passed to the child object.
## [2022-11-17]
### Breaking changes
- The order of `#[nested]` parameters in the parameter list now always follows
the declaration order instead of nested parameters being ordered below regular
parameters.
## [2022-11-08]
### Breaking changes
- The `Param::{next_previous}{_step,_normalized_step}()` functions now take an
additional boolean argument to indicate that the range must be finer. This is
used for floating point parameters to chop the range up into smaller segments
when using Shift+scroll.
## [2022-11-07]
### Breaking changes
- `Param::plain_value()` and `Param::normalized_value()` have been renamed to
`Param::modulated_plain_value()` and `Param::modulated_normalized_value()`.
These functions are only used when creating GUIs, so this shouldn't break any
other plugin code. This change was made to make it extra clear that these
values do include monophonic modulation, as it's very easy to mistakenly use
the wrong value when handling user input in GUI widgets.
## [2022-11-06]
### Breaking changes
- `nih_plug_vizia::create_vizia_editor_without_theme()` has been removed, and
`nih_plug_vizia::create_vizia_editor()` has gained a new argument to specify
what amount of theming to apply. This can now also be used to completely
disable all theming include Vizia's built-in theme.
- `nih_plug_vizia::create_vizia_editor()` no longer registers any fonts by
default. Even when those fonts are not used, they will still be embedded in
the binary, increasing its size by several megabytes. Instead, you can now
register individual fonts by calling the
`nih_plug_vizia::assets::register_*()` functions. This means that you _must_
call `nih_plug_vizia::assets::register_noto_sans_light()` for the default
theming to work. All of the plugins in this repo also use
`nih_plug_vizia::assets::register_noto_sans_thin()` as a title font.
- Additionally, the Vizia fork has been updated to not register _any_ default
fonts for the same reason. If you previously relied on Vizia's default Roboto
font, then you must now call `nih_plug_vizia::vizia_assets::register_roboto()`
at the start of your process function.
## [2022-10-23]
### Breaking changes
- `nih_plug_vizia` has been updated. Widgets with custom drawing code will need
to be updated because of changes in Vizia itself.
## [2022-10-22]
### Breaking changes
- The `Editor` trait and the `ParentWindowHandle` struct have been moved from
`nih_plug::plugin` to a new `nih_plug::editor` module. If you only use the
prelude module then you won't need to change anything.
- The `nih_plug::context` module has been split up into
`nih_plug::context::init`, `nih_plug::context::process`, and
`nih_plug::context::gui` to make it clearer which structs go with which
context. You again don't have to change anything if you use the prelude.
- NIH-plug has gained support for asynchronously running background tasks in a
simple, type-safe, and realtime-safe way. This sadly does mean that every
`Plugin` instance now needs to define a `BackgroundTask` type definition and
constructor function as Rust does not yet support defaults for associated
types (Rust issue [#29661](https://github.com/rust-lang/rust/issues/29661)):
```rust
type BackgroundTask = ();
```
- The `&mut impl InitContext` argument to `Plugin::initialize()` needs to be
changed to `&mut impl InitContext<Self>`.
- The `&mut impl ProcessContext` argument to `Plugin::process()` needs to be
changed to `&mut impl ProcessContext<Self>`.
- The `Plugin::editor()` method now also takes a
`_async_executor: AsyncExecutor<Self>` parameter.
## [2022-10-20]
### Breaking changes
- Some items have been moved out of `nih_plug::param::internals`. The main
`Params` trait is now located under `nih_plug::param`, and the
`PersistentTrait` trait, implementations, and helper functions are now part of
a new `nih_plug::param::persist` module. Code importing the `Params` trait
through the prelude module doesn't need to be changed.
- The `nih_plug::param` module has been renamed to `nih_plug::params`. Code that
only uses the prelude module doesn't need to be changed.
- The `create_egui_editor()` function from `nih_plug_egui` now also takes a
build closure to apply initialization logic to the egui context.
- `Editor` and the editor handle returned by `Editor::spawn` now only require
`Send` and no longer need `Sync`. This is not a breaking change, but it might
be worth being aware of.
- Similar to the above change, `Plugin` also no longer requires `Sync`.
## [2022-10-13]
### Breaking changes
- The `#[nested]` parameter attribute has gained super powers and has its syntax
changed. It can now automatically handle many situations that previously
required custom `Params` implementations to have multiple almost identical
copies of a parameter struct. The current version supports both fields with
unique parameter ID prefixes, and arrays of parameter objects. See the
[`Params`](https://nih-plug.robbertvanderhelm.nl/nih_plug/param/internals/trait.Params.html)
trait for more information on the new syntax.
## [2022-09-22]
### Breaking changes
- `nih_plug_vizia` has been updated. Custom widgets will need to be updated
because of changes Vizia itself.
- `nih_plug_egui` has been updated from egui 0.17 to egui 0.19.
## [2022-09-06]
### Breaking changes
- Parameter values are now accessed using `param.value()` instead of
`param.value`, with `param.value()` being an alias for the existing
`param.plain_value()` function. The old approach, while perfectly safe in
practice, was technically unsound because it used mutable pointers to
parameters that may also be simultaneously read from in an editor GUI. With
this change the parameters now use actual relaxed atomic stores and loads to
avoid mutable aliasing, which means the value fields are now no longer
directly accessible.
## [2022-09-04]
### Breaking changes
- `Smoother::next_block_mapped()` and `Smoother::next_block_exact_mapped()` have
been redesigned. They now take an index of the element being generated and the
float representation of the smoothed value. This makes it easier to use them
for modulation, and it makes it possible to smoothly modulate integers and
other stepped parameters. Additionally, the mapping functions are now also
called for every produced value, even if the smoother has already finished
smoothing and is always producing the same value.
## [2022-08-19]
### Breaking changes
- Standalones now use the plugin's default input and output channel counts
instead of always defaulting to two inputs and two outputs.
- `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.
## [2022-07-18]
### Breaking changes
- `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]
### Breaking changes
- There are new `NoteEvent::PolyModulation` and `NoteEvent::MonoAutomation`
events as part of polyphonic modulation support for CLAP plugins.
- 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.
## [2022-07-05]
### Breaking changes
- 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]
### Breaking changes
- 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`.
- Most `NoteEvent` variants now have an additional `voice_id` field.
- 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.
- 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.
## [2022-07-02]
### Breaking changes
- 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]
### Breaking changes
- 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]
### Breaking changes
- `Plugin::process()` now takes a new `aux: &mut AuxiliaryBuffers` parameter.
This was needed to allow auxiliary (sidechain) inputs and outputs.
- The `Plugin::initialize()` method now takes a `&mut impl InitContext` instead
of a `&mut impl ProcessContext`.
## [2022-05-22]
### Breaking changes
- 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.
- 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.

Who knows what happened at this point!
