### Added
- Added a timed cache for the `IPluginView::canResize()` VST3 function, so value
will be remembered during an active resize. This makes resizing VST3 plugin
editor windows more responsive.
- Add a cache for VST3 function calls where the host asks the plugin whether it
can process 32-bit or 64-bit floating point audio. Some hosts will call this
function every processing cycle even though the value doesn't change. Caching
this can significantly reduce the overhead of bridging VST3 plugins under
those hosts.
- Added a timed cache for the `IPlugView::canResize()` VST3 function, so the
result will be remembered during an active resize. This makes resizing VST3
plugin editor windows more responsive.
- Added another cache for when the host asks a VST3 plugin whether it supports
processing 32-bit or 64-bit floating point audio. Some hosts, like **Bitwig
Studio**, call this function at the start of every processing cycle even
though the value won't ever change. Caching this can significantly reduce the
overhead of bridging VST3 plugins under those hosts.
- Added a [compatibility
option](https://github.com/robbert-vdh/yabridge#compatibility-options) to
redirect the Wine plugin host's output directly to a file. Enabling this
allows **ujam** plugins and other plugins made with the Gorilla Engine such as
the **LoopCloud** plugins to function correctly as those plugins will throw a
seemingly unrelated error when they output to a pipe.
- Added a small warning on initialization when `RLIMIT_RTTIME` is set to some
small value. This happens when using PipeWire, and it can cause crashes when
using loading plugins.

### Changed
- Redesigned the VST3 audio socket handling to be able to reuse the process data
objects on both sides. This greatly reduces the overhead of our VST3 bridging
by getting rid of all memory allocations during audio processing.
by getting rid of all potential memory allocations during audio processing.
- VST2 audio processing also received the same optimizations. In a few places
yabridge would still reallocate heap data during every audio processing cycle.
We now make sure to always reuse all buffers and heap data used in the audio
processing process.
- Considerably optimized both VST2 and VST3 audio processing by preventing
unnecessary memory operations. As it turns out, the underlying binary
serialization library used by yabridge would always reinitialize the type-safe
unions yabridge uses to differentiate between single and double precision
floating point audio buffers, undoing all of our efforts at reusing objects
and preventing memory allocations in the process.
- VST3 output audio buffers are no longer zeroed out for the plugin. We did this
for VST3 plugins, but not for VST2 plugins. Since not doing this never caused
any issues with VST2 plugins it should also be safe to do the same thing for
VST3 plugins. This further reduces the overhead of VST3 audio processing.
- Further optimized VST3 audio processing by preallocating small vectors for
event and parameter change queues.
- VST2 audio processing also received the same small vector optimization to get
rid of any last potential allocations during audio processing.
- The same small vector optimization has been applied across yabridge's entire
communication and event handling architecture, meaning that most function
calls should no longer produce any allocations for both VST2 and VST3 plugins.
- Considerably optimized parts of yabridge's communication infrastructure by
preventing unnecessary memory operations. As it turned out, the underlying
binary serialization library used by yabridge would always reinitialize the
type-safe unions yabridge uses to differentiate between single and double
precision floating point audio buffers in both VST2 and VST3 plugins, undoing
all of our efforts at reusing objects and preventing memory allocations in the
process. A fix for this issue has also been upstreamed to the library.
- VST3 output audio buffers are now no longer zeroed out at the start of every
audio processing cycle. We did this for VST3 plugins since the introduction of
VST3 bridging in yabridge 3.0.0, but we never did this for VST2 plugins. Since
not doing this has never caused any issues with VST2 plugins, it should also
be safe to also skip this for VST3 plugins. This further reduces the overhead
of VST3 audio processing.
- Optimized VST3 audio processing for instruments by preallocating small vectors
for event and parameter change queues.
- VST2 MIDI event handling also received the same small vector optimization to
get rid of any last potential allocations during audio processing.
- This small vector optimization has also been applied across yabridge's entire
communication and event handling architecture, meaning that most plugin
function calls and callbacks should no longer produce any allocations for both
VST2 and VST3 plugins.
- Changed the way mutual recursion in VST3 plugins on the plugin side works to
counter any potential GUI related timing issues with VST3 plugins when using
multiple instances of a plugin.
