+- Additional changes to ExpressionTransformer ([#4614](https://github.com/dotnet/machinelearning/pull/4614))
+
+## **Test updates**
+- **Code analysis updates**


We don't ship code analyzer to our nuget users, why is this relevant to release notes?

+## **Test updates**
+- **Code analysis updates**
+  - Update analyzer test library ([#4740](https://github.com/dotnet/machinelearning/pull/4740))


We don't ship to users either.

+## **Test updates**
+- **Code analysis updates**
+  - Update analyzer test library ([#4740](https://github.com/dotnet/machinelearning/pull/4740))
+  - Enable the internal code analyzer for test projects ([#4731](https://github.com/dotnet/machinelearning/pull/4731))

docs/release-notes/1.5.0-preview2/release-1.5.0-preview2.md

+- **Better logging from tests**
+  - Ensure tests capture the full log ([#4710](https://github.com/dotnet/machinelearning/pull/4710))

+  - Collect crash dump upload dump and pdb to artifact ([#4666](https://github.com/dotnet/machinelearning/pull/4666))


How is collect crash dump relevant to nuget users? It will almost make them feel their data is being collected.

+- Added in support for System.DateTime type for the DateTimeTransformer ([#4661](https://github.com/dotnet/machinelearning/pull/4661))
+- Additional changes to ExpressionTransformer ([#4614](https://github.com/dotnet/machinelearning/pull/4614))
+
+## **Test updates**


This whole section is not shipped to the users, why is this included in release notes? Who is your target audience and why would they care about stuff that is not shipped part of nuget?

+
+## **CLI and AutoML API**
+  - CodeGen For AzureAttach ([#4498](https://github.com/dotnet/machinelearning/pull/4498))


We don't want user aware of this change because this is only for ModelBuilder Azure Attach story

plase add

Using invariance culture when converting to string ( #4635 )
and

Fix NullReferenceException when it comes to Recommendation in AutoML and CodeGenerator ( #4774 )

Thanks

+- TextLoader, BinaryLoader and SvmLightLoader now check the existence of the input file before training ([#4665](https://github.com/dotnet/machinelearning/pull/4665))
+- Changed onnx export to append a .onnx string to column names to support better mapping to ML.NET output column names ([#4734](https://github.com/dotnet/machinelearning/pull/4734))
+-	TextLoader, BinaryLoader and SvmLightLoader now check the existence of the input file before training ([#4665](https://github.com/dotnet/machinelearning/pull/4665))
+- ImageClassificationTrainer now checks the existence of input folder before training ([#4691]( https://github.com/dotnet/machinelearning/pull/4691))


this is ImagLoading transform not ImageClassification trainer, two very different things, one is a transformer and other is a trainer. #Resolved
