-commit fd604b269398aebdb0c5fa5511d9f3c38b6ecb45 (HEAD, origin/upgrade-ppxlib-0.18.0)
-Author: Nathan Rebours <nathan.p.rebours@gmail.com>
-Date:   Mon Oct 5 18:04:41 2020 +0200

-    Make ppx_sexp_message compatible with ppxlib.0.18.0
-    
-    ppxlib.0.18.0 upgrades to the 4.11 AST which results in a change
-    in string constants representation. This PR makes ppx_sexp_message
-    compatible with the latest ppxlib.
-    
-    You might want for the actual release of ppxlib.0.18.0 before merging
-    this!
