These are the release notes for our upcoming release. Welcome to the "insider club"!

Known Issues

The following operators have not been ported yet
- Audio Render CHOP
Leap Motion CHOP / Leap Motion TOP - The Leap Motion SDK has not been updated for Apple Silicon by Ultraleap, so it is not an option to add to these builds.
Movie File In TOP / Movie File Out TOP - The Cineform codec SDK does not look like it will be updated for Apple Silicon, so it is not an option to add to these builds.

Video Device In TOP - Added support for 'Sync Groups'.
Audio Binaural CHOP - A new CHOP for converting from a variety of audio formats to binaural.
Parameter CHOP / Parameter DAT - Added a new parameter 'ParGroups' to make selections by ParGroup.
WebRTC DAT - Added support for stereo audio output.

App Class.experimental (True/False) flag exposed.
DAT Class.scroll - Scroll by row/col works again for text DATs.
geotextCOMP Class - Class is now derived from geometryCOMP Class.
geometryCOMP Class.computeBounds - Updated to include boundaries of nested Geo Text COMPs.
Movie File In TOP.isOpen - Now dependable / can be used in parameter expressions.
WebrtcDAT Class.setLocalDescription - Added stereo keyword which specifies whether the local peer can receive stereo audio (default=False).
Fixed expressions involving OP to work the same in scripts as optimized expressions

For example:
op('geo1') + '_123'
op('geo1') * 3

Palette:particlesGPU - Added workaround for extra forces not removing emmitters due to samplerBuffer never decreasing in size.
Palette:pointField - v2.1.0 - Streamlined, performance improvements.
Palette:quadReproject - Hotfix, removing some leftover file paths to .py.
Palette:splitter - Hotfix, removing some leftover file paths to .py.
Palette:webBrowser - Added support for outputting audio via the Audio Web Render CHOP.
Palette:camSchnappr - Project also contains table for raw intrinsic values to be used with 3rd party applications.
Palette:camSchnappr - Updated blendregion calculation to follow this paper: https://www.researchgate.net/publication/236942993_Automatic_blending_for_arbitrary-shaped_projection_surfaces
WebRTC Toolkit improvements
- Palette:signalingServer / Palette:signalingClient - v1.0.1 - Fixing an issue where some internal tools were referencing development files.
- Palette:webRTC - v1.0.2 - Fixing an issue where some internal tools were referencing development files.
- Palette:webRTC - v1.0.2 - Adding support for stereo audio.

Widgets - Fixed default path loss. Also BasicWidgets component now has display flag off.

Actor COMP - Fixed diagonal drifting of particles while using velocity feedback in Flex.

Engine COMP - Fixed issue which could cause outputs not to update sometimes if they cooked only in the first frame.
Engine COMP - Fixed delayed memory release if a DAT output was removed.

Environment Light COMP - Fixed shader not working for Prefilter = Off setting.

Geometry COMP - Instance Texturing now works on macOS (although with much fewer textures possible than on Windows).

Geo Text COMP - Fixed horizontal alignment when using appended lines in the 'Specification DAT'.
Geo Text COMP - Local transforms using the 'Specification CHOP' or 'Specification DAT' now pivot around the center of the text rather than the bottom left.
Light COMP - Fixed crashes that can occur when disabling cook flag on Light COMPs or the TOPs they reference.
Text COMP - Increased the height of the cursor and selection highlight.

Movie File In TOP - Handle loading .bmp files that have negative height in their header.
Notch TOP - Fixed reported block_render_time not updating unless MMB info is active.
Render TOP - Fixed hang that can occur when doing Depth Peeling.
Render Select TOP - Fixed 'Image Output' not returning the correct texture.
Syphon Spout In TOP - Fixed texture not working when used in a MAT that has mipmapping on.

Video Device In TOP - Fixed deinterlace feature not working.
Video Device In TOP - Fixed crashes that can occur with some camera inputs, virtual cameras in particular.
Video Device In TOP - Fixed some hangs that can occur when using Media Foundation library.
Video Device In TOP - Fixed some errors when converting YUV To RGB that were introduced in the 2022.20000 series.
Video Device In TOP - Improved playback smoothness when input framerate is higher than the TouchDesigner framerate.
Video Device Out TOP - Fixed large cook times when using pinned memory with Blackmagic devices.
Vioso TOP - Fixed issue with loading warp texture.

Blend CHOP - Fixed undercooking when using Quaternions.
Info CHOP - Scope parameter now works for other Info Types.
Leap Motion CHOP / Leap Motion TOP - Re-enabled on Intel Macs. Ultraleap has not made the Leap Motion SDK available for Apple Silicon so at this time we do not have a timeline for Leap Motion on macOS Apple Silicon builds.
Script CHOP - Callback DAT now defaults to Python syntax highlighting.
Timer CHOP - general improvements.
- 'External Start Offset' / 'External Init Offset' parameters to control how the external CHOP channel input is applied for timing.
- Limit onInitialize callbacks to one per frame, not one per timeslice sample.
- Fixed crash when tied to timeline and changing column output values.
- Segment objects now compare against non-numbers properly.

For Example: if (segment != None) ...

Text DAT - Fixed a crash when hitting Ctrl+Delete or Ctrl+Backspace to delete the node while editing.
UDP In DAT - Fixed memory leak when using onReceive callback.
WebRTC DAT - Enable on Apple Silicon (arm64 builds).

WebSocket DAT - Fixed 'Bytes' column, receiving of fragmented messages, and the triggering of onConnect/onDisconnect callbacks when pulsing 'Reset' parameter.
Web Server DAT/WebSocket DAT - Fixed a crash when sending a frame at the same time as the connection is reset on the remote end.

MAT - MAT nodes can no longer be bypassed by doing a bypass while they are group selected with another node type.
Constant MAT - Fixed crash when a TOP it was referencing is bypassed.

Performance monitor now includes unaccounted time *before* total time.
Exposed all installer options as command line parameters.
Fixed slow memory leak that can occur in some cases.
Fixed connecting non-components to multi-input components.
Fixed a bug setting the focus on popMenus.
Stopping the timeline in Execute DAT onStart() will now keep it stopped after launch.
Export Movie Dialog - Fixed file browser selection for the recorded movie's filename.
Fixed crash when using normalized TOP view on 3D textures.
