summarization removed from pipeline

In the "transformers, what can they do?" section of the course, the following code no longer compiles:

from transformers import pipeline

summarizer = pipeline("summarization")
summarizer(
"""
America has changed ......
"""
)

The following error is produced:
KeyError: "Unknown task summarization, available tasks are ['any-to-any', ......]

It appears that the summarization task has been removed from the pipeline.
