Quake II 5.21 to 5.22:
- Provide a fallback if SDL2s relative mouse mode
  cannot be activated.

Quake II 5.20 to 5.21:
- Fix a bug regaring mouse key handling (reported 
  by phenixia2003)
- Correct MS Windows builds. Add official support
  for Win64. This still needs some testing.
- Allow to shutdown the client by pressing ctrl-c
  or sending SIGTERM. Unix / Linux only.

Quake II 5.11 to 5.20
- Integrate the refresher into the client and
  remove QGL. This means that ref_gl.so is gone
  and libGL is now linked like every other lib.
  (by Alejandro Ricoveri)
- Port the client to SDL 2.0. The newer SDL version
  solves some long standing problems, like broken
  keyboard layouts and non working SDL sound on
  Windows. While SDL 2.0 is enabled by default,
  one can switch back to SDL 1.2 by editing the
  Makefile.
- OS X support was put to hold. While OS X support
  is nice to have, non of the deveolpers has
  interest in maintaining it. Until someone steps
  up and takes responsibility, no OS X versions
  will be released.

Quake II 5.10 to 5.11
- A lot of bugfixes.
- Videos are scaled to 4:3 to prevent distortions.
- Another sound system cleanup.

Quake II 5.00 to 5.10
- Support for OS X. (by W. Beser)
- Correct field of view handling (by Ricardo Garci)
- Many improvements to the mouse release code (by svdijk)
- Scrolling save / load menus (by svdijk)

Quake II 4.21 to 5.00
- Backport to Microsoft Windows.
- Support for OpenBSD. (by Jonathan Gray)
- Aspect ration can be set via the video menu.
- A better random number generator.
- The SDL sound driver is now selectable by
  "s_sdldriver".

Quake II 4.20 to 4.21
- Fix several segfaults with OpenAL. (reported by 
  Joran and mxmvasilyev0)
- Add a file CONTRIBUTE.
- Some minor changes to the Makefile.

Quake II 4.10 to 4.20
- Add an options framework to allow disabling most
  option features (OGG/Vorbis, ZIP file loading,
  OpenAL, etc) at compile time.
- Integrate OpenAL support, enabling surround sound
  and better stereo sound calculations.
- Enforce the "C" locale to prevent libraries like
  broken LADSPA plugins to override it and break
  printf, scanf, etc.

Quake II 4.03 to 4.10
- Change the behavior of hotkey menus to fix some
  strange bugs and memory leaks in the menu system.
- Add the "gl_farsee" cvar. When set to "1" Quake II
  renders maps up to 4096x4096 units instead of being
  limited to 2300x2300. The default is "0". (by Richard
  Allen)
- Add support for the high resolution retexturing pack.
- Reenable support for gamma via SDL, since the upstream
  bug was fixed with SDL 1.2.15. Gamma via X11 can be
  forced by defining X11GAMMA at compile time.
- Add support for big endian architectures and enable
  the build on SPARC64 CPUs. (by Kieron Gillespie)

Quake II 4.02 to 4.03
- Fix wrong function call in the Quake II file system.
- Fix gl_ext_multitexture set to 1. (reported by Richard Allen

- ctf was moved into a separate download.
- All open bugs were fixed.
- Fix spawnpoint selection if single player maps are loaded via console.
- Rename ~/.quake2 to ~/.yq2 to ease parallel installation with other
  Quake II clients.
- The client does no longer crash if the menu is opened while connecting
  to remote server.
- The game code received a code audit and major rework.

Quake II 3.00RC2 to 3.00
- Improve compatiblity with pulseaudio (by Ozkan Sezer)

Quake II 3.00RC1 to 3.00RC2
- Many improvements to the OGG/Vorbis support. (by Ozkan Sezer)
- The map command now works even when a server is running.

Quake II 2.11 to 3.00RC1
- Complete refactoring and code audit of the client, leading
  to much cleaner and more maintainable code and improved
  stability.

  sudden crashes.
- Reworked the input system.
- Much improved console tab completion.
- Better TTY output of the startup and shutdown.

	This should fix the gamma for all setups.
  - Support for overbright bits.
- Changed the window title to "Yamagi Quake II".

- Fix a bug in the client. This fixes the strange crashes
  under Ubuntu. (Reported by many, special thanks to jhansonxi
  for his help)
- Add a null pointer check in cl_view.c. This fixes a rare
  case crash in Ground Zero when files are missing. (by Sascha K.)
- Add a script as possible work around for Ubuntu bug 32452 (by caedes)
