 Plain conditionalization only covers the case when new evidence acquires the maximum degree of certainty. Spohn (1988) also defines a ranking-theoretic analogue to Jeffrey conditionalization. In this case, new evidence does not acquire maximum certainty, but merely changes your ranks for various propositions. For more on ranking-theoretic notions of belief update see Huber (2014, 2019). For a comparison of probability theory and ranking theory see Spohn (2009, Section 3)
