* Isar/Pure: local results and corresponding term bindings are now subject to Hindley-Milner polymorphism (similar to ML); this accommodates incremental type-inference nicely; * Isar/Pure: new calculational elements 'moreover' and 'ultimately' support plain accumulation of results, without applying any rules yet;

 * Pure: scalable support for case-analysis type proofs: new 'case'
 language element refers to local contexts symbolically, as produced by
 certain proof methods; internally, case names are attached to theorems
 as "tags";

 * Provers: splitter support (via 'split' attribute and 'simp' method
 modifier); 'simp' method: 'only:' modifier removes loopers as well
 (including splits);
