Most of the other packages like CMS and Commerce now have support for Newtonsoft.Json 12, but I can not use it because Find does not support it yet.
I am also very curious if an update to support at least < 13 is planned any time soon.
+1. While waiting for this, we are forced to use an old version of ReactJS.NET, which is not ideal.
Another relevant thread from 2018/2019: https://world.episerver.com/forum/developer-forum/Feature-requests/Thread-Container/2018/12/update-all-packages-to-support-newtonsoft-json-v12/
+1 Also waiting on this.
Episerver.Find.Commerce even supports 12:
Newtonsoft.Json (>= 10.0.3 && < 13.0.0)
But it cannot be installed because it needs Episerver.Find, which as stated above does not support 12.
Find version 13.2.6, released today, includes Find 6415, which provides support for Newtonsoft.Json 13.0.
I see that Epi Find is lacking support for Newtonsoft.Json 12.
Is that planned to be released soon?
