Hihglights:
π Python 3.5 support has been dropped.
π 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.
π You can now choose whether feed exports overwrite or append to the output file.
π For example, when using the crawl or runspider commands, you can use the -O option instead of -o to overwrite the output file.
π 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.
