 * [#] 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
