Subject: [bug#47768] ocaml - how can we get more recent version of core-kernel and common ppx'es
Date: Sat, 29 May 2021 22:01:19 +0000

I have now applied the patches locally and tested a handful of the 
updated packages, and things appear to be working fine for me. Thanks a 
lot for doing this!

What is the process for getting these patches commited to master? Do we 
need someone to test that the patches didn't break any existing package?
