## 4.30. Client/Library changes

- The libraries have been updated to R6.3. The shared lib version numbers for libXext and libICE have been bumped to 6.3. The others remain the same.
- An Xlib problem with non-latin-1 encodings that shows up when using XKB is fixed.
- Some Xlib security vulnerabilities have been fixed.
- Xterm's emulation of DECUDK (DEC user-defined keys) now (correctly) interprets shifted keys only.
- VT52 emulation has been added to xterm.
- Xterm's VT100 emulation generates correct codes for PF1-PF4, as well as the keypad "+" and ",". These codes differ from the VT220 emulation.
- Some xterm bugs have been fixed, including coloured background exposure while selection is active, and missing state changes in the VT100 emulation.
- Xterm's memory requirements for colour have been reduced. The colour resource file is merged with the regular resource file to reduce installation problems.
- Emulation of VT220 soft-reset, and non-DEC REP (repeat) control sequence has been added to xterm.
- Xterm now recognizes control sequences for 16 colors (from aixterm).
- xset includes support for the DPMS extension.
- xset's "r rate" flag was broken on some OSs, and is now fixed.
