Installed Fedora-31. The big difference I feel is, previously when I typed in Bengali in console, some of the unicode characters hanged the terminal. Therefore I had to gedit the file and then edit it in GUI for adding Bangla.
This problem seems to have been fixed. Now I can type in as much Bangla in console mode as I with without any problem.
This isn't a OS level change, rather a package level update, but whatever. It's fixed from this release.
