Moving forward, we are going to be aligning more with the overall .NET release schedule. As such, this is a smaller release since we had a larger one just about 3 months ago but it aligns us with the release of .NET 6.
New Features
ML.NET
Switched to getting version from assembly custom attributes- (#4512) Remove reliance on getting product version for model.zip/version.txt from FileVersionInfo and replace with using assembly custom attributes. This will help in supporting single file applications. (Thanks @r0ss88)
Can now optionally not dispose of the underlying model when you dispose a prediction engine. (#5964) A new prediction engine options class has been added that lets you determine if the underlying model should be disposed of or not when the prediction engine itself is disposed of.
Can now set the number of threads that onnx runtime uses (#5962) This lets you specify the number of parallel threads ONNX runtime will use to execute the graph and run the model. (Thanks @yaeldekel)
The PFI API has been completely reworked and is now much more user friendly (#5934) You can now get the output from PFI as a dictionary mapping the column name (or the slot name) to its PFI result.
DataFrame
Can now merge using multiple columns in a JOIN condition (#5838) (Thanks @asmirnov82)
Enhancements
ML.NET
Run formatting on all src projects (#5937) (Thanks @jwood803)
Added BufferedStream for reading from DeflateStream - reduces loading time for .NET core (#5924) (Thanks @martintomasek)
Update editor config to match Roslyn and format samples (#5893) (Thanks @jwood803)
