There is More Than RTL

This list does not include units outside of the core RTL. which include FireDAC, DataSnap, EMS, WebBroker, Indy, and DunitX.

The new version of Delphi is bringing to the Linux platform a lot of technology. True, there is no ready-to-use GUI support, but there are a lot of keep developers happy.

In the next blog, learn about the value of the added full GUI and X windows support to the Windows Subsystem Linux (WSL2).
