> [PR 35243|https://github.com/apache/spark/pull/35243] introduced a new parameter to class `Invoke` with a default value (`isDeterministic: Boolean = true`). Existing Spark libraries (such as [frameless|https://github.com/typelevel/frameless]) that invoke [Invoke|https://github.com/typelevel/frameless/blob/29961d549e332dddf5cd711ef699dde7460cc48a/dataset/src/main/scala/frameless/RecordEncoder.scala#L154] directly expect a method with 7 parameters, and the new version expects 8. If Frameless would recompile with Spark 3.2.1, the updated library will NOT be binary compatible with Spark 3.2.0. Adding default parameters to existing methods [should be avoided|https://github.com/jatcwang/binary-compatibility-guide#dont-adding-parameters-with-default-values-to-methods].
> One way forward would be to revert the change in the constructor and introduce a second constructor or a companion method that takes all the 8 parameters.
