Lines 328 to 330 in 8adafa5

	self.clustering = AgglomerativeClustering(n_clusters=None, linkage="single", distance_threshold=delta, affinity="euclidean")
	else:
	self.clustering = AgglomerativeClustering(n_clusters=None, linkage="single", distance_threshold=delta, affinity="precomputed")

Attribute affinity was deprecated in version 1.2 and will be removed in 1.4. Use metric instead.
