I've not got a D10 test bed yet, this issue was flagged to me by the upgrade_status module in my D9 build. This project is a complex multi-layer migration from D6, D7, D8 and Word documents into a single database and requiring a lot of data processing to resolve inter-database formatting issues, so I've been doing incremental builds from D8 on-wards, but got stumped trying to go D9-10. Applying the patch and re-running the upgrade_status report (with scanning enabled for this module) gives me a "compatible" result. This as far as I'm able to test in my current environment, sorry.
Has anyone tested this patch? I have a custom module which extends this module, but the upgrade status module is flagging this module, the patch would appear to be just adding D10 to the info file. Adding the patch locally seems to work, but I don't have the experience to make a code change to the repository.
