New omni.client extension (all extensions using python/C++ client lib should set this as extension dependency).
omni.client python binding.
OmniClient.h C++ dynamic library interface.
OmniClient carbonite interface.
DataSource interface with carb.datasource-omniclient.plugin implementation.
Direct use of Connection Library, IConnectionHub, omni_usd_plugin, omni.connection, omni.connectionhub, omni.usd_plugin are now deprecated. Any new carbonite plugins, Kit extensions should develop with client library/omni.client directly. Any old extensions/scripts/plugins using these components will stop working and need to be updated.
URL format has changed. You do not need to make an explicit connection to a server to access the files, instead you specify the server name in the URL. For example if you want to load a file from localhost, previously you need to log into localhost first, then open omni:/Users/foo/bar.usd. Now you can open omniverse://localhost/Users/foo/bar.usd directly. Client library manages the connection internally.
With the new URL format, you can now reference USD layers across servers (experimental, material may not work properly).
Old omni: URL will still work in USD, but it’s recommended to update your files to use the full qualified omniverse:// URL.

Proper package name for extensions (using version and package.target)
Version removed from premake and moved into extension.toml.
Extension.toml reworked, added [package] section to avoid polluting root, added various info for UI here.

New way to process Kit experience configuration files, allowing configuration merging using –merge-config/-m command line arguments, with experimental support of configuration file imports (using “@import@” directive) and appending array values using “++” child field.
Kit data path now includes build number

omni.anim.jiggle extension to simulate the secondary jiggle bounce mesh deformation
Add options in the Preference window to select default xformOp when creating new prims
Add support of USD layer offset such that animations in different layers with different timeCodePerSecond can play together, a.k.a auto retiming.
Add Transform spline interpolation supported in omni.anim.timesample_editor , such that the key framed xForm value can be evaluated in Bezier curve interpolation method.
Moved the timeCodePerSecond editing feature from the timeline UI to the omni.anim.timesample_editor window
Switched the default animation time unit from seconds to frames in the timeline UI
Improved the robustness of omni.anim.player such that it can playback almost all kind of animation scene. The only exception is the none-OmniGraph skeleton mesh pipeline, it is a known issue and will be address in the next release.
Moved Omni::UI to a separate extension
New embeddable omni.kit.widget.filebrowser UI widget for exploring file systems, including nucleus servers.
New widget, ImageWithProvider and a set of helper ImageProviders, which serve as a source of image data for the widget. ByteImageProvider allows to display raw byte data, RasterImageProvider allows to load a raster image and display it, VectorImageProvider allows to load vector image, rasterize it and display.
TreeView: rewrote to avoid using ImGui table
TreeView: the ability to reorder items
Added new extension omni.graph.ui that allows inspect omni.graph and UsdShade networks as graph view

Kit control port extension is now part of Omniverse. It forms the base of the micro services framework that is being built around it. It
Kit-services is an application that makes it easy to get going with Kit and its micro services framework. Build, run and deploy kit microservices.
Basic facilities that make it easier to write stateless services using dependency injection.
Early preview of the new hydra viewport extension in kit, accessed by running kit-hydra.bat in Windows. This viewport renders the USD world using render delegate plugins like Pixar’s OpenGL based hdStorm and hdEmbree. This allows kit to run on machines with non-RTX GPUs and be embedded in lightweight, quick loading experiences. The hydra viewport is not yet feature complete, but picking and camera controls are implemented.
