As you have probably seen, Embarcadero has released a few patches for 10.2.3. I wrote about them at http://blog.marcocantu.com/blog/2018-april-10-2-3-patches-recap.html and there was a new one for iOS covered by Sarina at https://community.embarcadero.com/blogs/entry/rad-studio-10-2-3-ios-11-3-patch-available.
Yesterday, the compony released a patch that addresses a few critical issues when deploying RAD Server modules to Apache on Linux. The reported bug mentioned is not the key one, as the main issue was found and reported internally and not on Quality Portal. If you have any interest in deploying a RAD Server solution to Linux, this patch is a must have.
The download is at https://cc.embarcadero.com/item/30836 .
Just in case you missed is, remember that part of a RAD Studio. Delphi, or C++Builder Enterprise or Architect product, you now have the license to deploy a single RAD server instance without any further cost.
