In this document, Ctrl means Cmd on Mac.

### 2.2.3 (2023-01-25)
- Place module selection nearest to mouse position when pasted and nearest to the center of the rack viewport when imported.
- Allow custom menu items to be appended to port's context menu.
- Fix ignored MIDI input messages while using small audio block sizes.

	- Make CLAP adapter a Note Effect and Audio Effect as well as an Instrument.
- API
	- Make unarchiver handle zero-byte files as a special case by deleting destination files instead of overwriting them. This allows plugin packages to remove old presets by including a zero-byte file with its filename.
	- Add `ModuleWidget::getModule<TModule>()` convenience method.

### 2.2.2 (2022-12-27)
- Display Rack edition, version, OS, CPU, and plugin type in menu bar to help with troubleshooting.

- Rack Pro
	- Fix blank plugin window on certain Linux Nvidia graphics drivers.
- API
	- Don't include SIMDE headers on x64, fixing symbol conflicts when plugins include x64 intrinsic headers.
	- Don't export symbols from libarchive, zstd, rtaudio, and rtmidi to avoid conflicts with hosts that use these libraries. Rack plugins can no longer link to these libraries.

### 2.2.1 (2022-12-07)
- Add `CROSS_COMPILE` environment variable to specify target triplet for building plugins for non-native architectures.
- Accept `aarch64` in target triplet as alias for ARM64.

	- Fix VST3 not receiving MIDI CC input from DAWs.
	- Fix VST3 not sending MIDI output to some DAWs.
	- Fix VST3 in Bitwig resetting parameters when adding/removing modules.

	- Add `Module::SaveEvent`.
	- Add operator overloads for `Vec`.
	- Add `string::join()`, `split()`, `formatTime()`, and `formatTimeISO()`.
