Write Indexing Pipeline Extensions Using Python 3
Since Python 2 is about to be deprecated, you must start using Python 3 when writing indexing pipeline extensions. A Python Version dropdown menu is therefore available in the extension creation panel to allow you to indicate that your new extension is written using Python 3.
Conditions Now Support Date Ranges
When creating a query pipeline condition, you can now enter a date range for the Query Time UTC object. This allows you to use a specific pipeline or apply pipeline rules only when queries are performed between two dates. You can use this object to show certain products at the top of the results list during promotions and sales.
