Hihglights:

• Python 3.5 support has been dropped.

• The file_path method of media pipelines can now access the source item.

  This allows you to set a download file path based on item data.

• The new item_export_kwargs key of the FEEDS setting allows to define keyword parameters to pass to item exporter classes.

• You can now choose whether feed exports overwrite or append to the output file.

  For example, when using the crawl or runspider commands, you can use the -O option instead of -o to overwrite the output file.

• Zstd-compressed responses are now supported if zstandard is installed.

• In settings, where the import path of a class is required, it is now possible to pass a class object instead.
