 * LUCENE-9929: Add NorwegianNormalizationFilter, which does the same as ScandinavianNormalizationFilter except
   it does not fold oo->ø and ao->å. (janhoy, Robert Muir, Adrien Grand)
 
-* LUCENE-9981: Operations.getCommonSuffix/Prefix(Automaton) is now much more
-  efficient, from a worst case exponential down to quadratic cost in the
-  number of states + transitions in the Automaton.  These methods no longer
-  use the costly determinize method, removing the risk of
-  TooComplexToDeterminizeException (Robert Muir, Mike McCandless)
-
-* LUCENE-9981: Operations.determinize now throws TooComplexToDeterminizeException
-  based on too much "effort" spent determinizing rather than a precise state
-  count on the resulting returned automaton, to better handle adversarial
-  cases like det(rev(regexp("(.*a){2000}"))) that spend lots of effort but
-  result in smallish eventual returned automata.  (Robert Muir, Mike McCandless)

 * LUCENE-9944: Allow DrillSideways users to provide their own CollectorManager without also requiring
   them to provide an ExecutorService. (Greg Miller)
