Noteworthy security fix:

- On Windows, if a server sent control sequences at high speed to reconfigure the terminal window title repeatedly, PuTTY would pass on all those title changes to Windows itself at high enough speed to make the window system unresponsive, resulting in a denial of service to other local applications.

Noteworthy UI fix:

- The terminal was unable to display Unicode characters in the range U+F000 to U+F1FF (part of the private-use area).

This latest one is amazing for the ones of us who like to pimp our terminal using nerdfonts, fancy icons in the terminal and such. This now finally works well!
