 ### Minor changes to the library {#minor_library_changes}
 
+#### go/types
 
+The `Var.Kind` method returns an enumeration of type `VarKind` that
+classifies the variable (package-level, local, receiver, parameter,
+result, or struct field). See issue #70250.
+
+Callers of `NewVar` or `NewParam` are encouraged to call `Var.SetKind`
+to ensure that this attribute is set correctly in all cases.

 ### Go command {#go-command}
 
+The `go build` `-asan` option now defaults to doing leak detection at
+program exit.
+This will report an error if memory allocated by C is not freed and is
+not referenced by any other memory allocated by either C or Go.
+These new error reports may be disabled by setting
+`ASAN_OPTIONS=detect_leaks=0` in the environment when running the
+program.
