Original release notes

Renamed Group to Lane
Group already represented a lane in practice, so renaming the module to Lane greatly simplifies the core concepts. A top-level lane is now simply a Lane submodule of the root Stack. For consistency, MIDI Group was also renamed to MIDI Lane. Note that the patch migrator will not rename modules with "Group" in their title, although the module type will change to Lane.

Other Changes
- Added support for 16-voice polyphony.
- Voice Activity: Updated the module to support 16 voices.
- Collapsed lanes now remain in place, so their visual layout reflects the signal-flow order, with consecutive collapsed lanes displayed side by side.
- Arpeggiator: Improved the Manual and Free modes by keeping the active note indicator visible alongside the Position slider.
- Patches: Patches with a Lane as the root now open with it as a top-level Lane instead of wrapping it in another Lane.
- Factory Patches: Added "Arp Improvisor" to MIDI FX and "Free Arpeggiator" to Subpatches to demonstrate Arpeggiator Free mode.
- Fixed a rare crash when the Pitch Ratio module was displayed before the host started rendering audio.
- Fixed a rare crash caused by hosts rendering larger audio buffers than the plug-in was configured for.
