Hi Prasad;
As far as compiling - the process has not changed IDE wise. In 2021 there is also an optional external compiler called PBAutoBuuld for batch compiling (ie for CB/CI work).
The only difference when deploying an EXE is to now note that the compilers create a new <app name>.XML file. This XML file needs to be deployed with your App EXE.
Optionally, you can also check out the new web server deployment feature called PowerClient. This allows you to deploy your App directly to a web server & then have your app users install & run the app via a standard URL. Updates as well will follow this new architecture.
All of the above is well documented in the PB help.
HTH. Regards... Chris
