Changes marked * [#] View shifts are radically simplified to just internalize frame-preserving updates. Weakestpre is defined inside the logic, and invariants and view - shifts with masks are also coded up inside Iris. + shifts with masks are also coded up inside Iris. Adequacy of weakestpre + is proven in the logic. * [#] The language can now fork off multiple threads at once. ## Iris 2.0 -This version accompanies the final ICFP paper. - -* [algebra] Make the core of an RA or CMRA a partial function. * [heap_lang] No longer use dependent types for expressions. Instead, values carry a proof of closedness. Substitution, closedness and value-ness proofs are performed by computation after reflecting into a term langauge that knows about values and closed expressions. * [program_logic/language] The language does not define its own "atomic" predicate. Instead, atomicity is defined as reducing in one step to a value. +* [program_logic] Due to a lack of maintenance and usefulness, lifting lemmas + for Hoare triples are removed. + +## Iris 2.0-rc2 + +This version matches the final ICFP paper. + +* [algebra] Make the core of an RA or CMRA a partial function. * [program_logic/lifting] Lifting lemmas no longer round-trip through a user-chosen predicate to define the configurations we can reduce to; they directly relate to the operational semantics. This is equivalent and much simpler to read. - Due to a lack of maintenance and usefulness, lifting lemmas for Hoare triples - are removed. ## Iris 2.0-rc1
