In this changelog, we document "large-ish" changes to Iris that affect even the
way the logic is used on paper. We also mention some significant changes in the
Coq development, but not every API-breaking change is listed. Changes marked
[#] still need to be ported to the Iris Documentation LaTeX file.
## 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.
## Iris 2.0-rc1
This is the Coq development and Iris Documentation as submitted to ICFP.
