Embarcadero have just announced the availability of RAD Studio Rio 10.3.1. This follows (fairly) hot on the heals of Rio 10.3 which was released in Nov 2019
This release has some minor new additions but is basically a bug fix release. You have to uninstall 10.3 and then install 10.3.1 using the same type of installer (either ISO or www) that you originally used for the 10.3 install.
