Quake II 6.00 to 7.00:
- Remove the broken multitexturing render path from the OpenGL 1.4
  renderer. It was switched off by default in 6.00.
- Reimplement the support for shared renderer libraries. Please note
  the this is an incompatible implementation with an custom API. The
  original renderer libraries will not work!
- Implement an OpenGL 3.2 renderer. This renderer has the same look
  and feel as the old OpenGL 1.4 renderer but makes heavy use of
  modern OpenGL and GPU features. An OpenGL 3.2 capable GPU (Intel
  starting with Ivy Bridge, Nvidia staring with G80 and AMD starting
  with R600 / HD2000) is required.
- Fix OpenAL compatibility with modern openal-soft versions.
- Several fixes and optimizations to OpenAL, implement support for
  doppler effects. (by xorw)

Quake II 5.34 to 6.00:
- Make the client asynchronous. The old behaviour can be forced by
  setting cl_async to 0. Please note that asynchronicity can lead to
  problems if the old SDL 1.2 backend is used and vsync is enabled.
- Implement gl_overbrightbits in the non multitexturing case.  A value
  of 1 just fixes lighting on water surfaces, higher values increase
  the brightness of everything.
- General renderer overhaul for better compatibility with modern GPUs.
  OpenGL 1.4 is now required, older versions are no longer supported.
  Multitexturing was deprecated and will be removed in a future release.
- Fix some longstanding AI problems.
- Several general gameplay fixes.

Quake II 5.33 to 5.34:
- Add support for stereo 3D (by Valery Guskov)
- Make gibt solid so they move with conveyor belts.
- Disable gl_ext_multitexturing by default.
- Switch from an arch whitelist to an "all archs are supported"
  approach.
- Add a new README.

- Provide gl_consolescale and gl_menuscale cvars to change the scale
  of the console and the menu.

  were fixed and the underwater effect is now supported in the SDL
backend. (by bibendovsky)

Quake II 5.22 to 5.23:
- Provide gl_hudscale cvar that can be changed to scale the HUD, for
  high resolutions etc. (by caedes)

Quake II 5.11 to 5.20
- Integrate the refresher into the client and remove QGL. This means

  (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.

  (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
