There are two new extension commands for SPSS Statistics posted on the Extension Hub.
STATS CONVERT PYTHON converts Python 2 code in .py or .sps files to Python 3. Statistics version 27 does not support Python 2 out of the box. There is an article about it in the Files section of this site.
STATS RESIDUAL BOXPLOTS produces a set of linked boxplots for residuals against predicted values from regression or similar procedures. The plot can help identify heteroscedasticity and functional form problems in the model. The installation of this extension includes an article on its usage.
